Acr_cloud_sdk: ACR Cloud SDK for Flutter

ACR Cloud SDK

** This is an unofficial SDK for flutter

Automatic content recognition (ACR) is an identification technology to recognise content played on a media device or present in a media file. This enables users quickly obtain detailed information about the content they have just experienced without any text based input or search efforts.

🤔 How ACR works

ACR can help users deal with multimedia more effective and make applications more intelligent. More info.

📸 Screen Shots

🚀 Initialize SDK

  final AcrCloudSdk arc = AcrCloudSdk();
  
      arc..init(
          host: '', // obtain from https://www.acrcloud.com/ 
          accessKey: '', // obtain from https://www.acrcloud.com/ 
          accessSecret: '', // obtain from https://www.acrcloud.com/ 
          setLog: false,
        )..songModelStream.listen(searchSong);
  
  void searchSong(SongModel song) async {
      print(song); // Recognized song data
  }

Initialize sdk and listen for song recognition events.

️🎶 Start Recognition

 bool started = await arc.start();
  • This function will automatic start the recording and recognizing process.
  • When there’s a result, songModelStream & resultStream will return the data as events.
  • The whole recognition time is controlled by ACRCloud’s Server.
  • You can call the stop function to terminate this process.

⛔ Stop Recognition

 bool started = await arc.stop();
  • This function will cancel the recognition immediately.

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add acr_cloud_sdk

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  acr_cloud_sdk: ^2.0.1

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:acr_cloud_sdk/acr_cloud_sdk.dart';

example/lib/main.dart

import 'package:acr_cloud_sdk_example/utils/log.dart';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';

import 'package:hooks_riverpod/hooks_riverpod.dart';

import 'utils/theme.dart';
import 'views/home_page.dart';

void main() {
  Log.init(kReleaseMode);
  runApp(ProviderScope(child: MyApp()));
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    overrideDeviceColors();
    return MaterialApp(
      title: 'SoundCheck',
      debugShowCheckedModeBanner: false,
      theme: themeData(context),
      home: HomePage(),
    );
  }
}

Acr_cloud_sdk: ACR Cloud SDK for Flutter

A User-space File System for interacting with Google Cloud Storage

gcsfuse is a user-space file system for interacting with Google Cloud Storage.

Current status

Please treat gcsfuse as beta-quality software. Use it for whatever you like, but be aware that bugs may lurk, and that we reserve the right to make small backwards-incompatible changes.

The careful user should be sure to read semantics.md for information on how gcsfuse maps file system operations to GCS operations, and especially on surprising behaviors. The list of open issues may also be of interest.

Installing

See installing.md for full installation instructions for Linux and macOS.

Mounting

Prerequisites

GCS credentials are automatically loaded using Google application default credentials, or a JSON key file can be specified explicitly using --key-file. If you haven't already done so, the easiest way to set up your credentials for testing is to run the gcloud tool:

gcloud auth login

See mounting.md for more information on credentials.

Invoking gcsfuse

To mount a bucket using gcsfuse over an existing directory /path/to/mount, invoke it like this:

gcsfuse my-bucket /path/to/mount

Important: You should run gcsfuse as the user who will be using the file system, not as root. Do not use sudo.

The gcsfuse tool will exit successfully after mounting the file system. Unmount in the usual way for a fuse file system on your operating system:

umount /path/to/mount         # macOS
fusermount -u /path/to/mount  # Linux

If you are mounting a bucket that was populated with objects by some other means besides gcsfuse, you may be interested in the --implicit-dirs flag. See the notes in semantics.md for more information.

See mounting.md for more detail, including notes on running in the foreground and fstab compatibility.

Performance

Latency and rsync

Writing files to and reading files from GCS has a much higher latency than using a local file system. If you are reading or writing one small file at a time, this may cause you to achieve a low throughput to or from GCS. If you want high throughput, you will need to either use larger files to smooth across latency hiccups or read/write multiple files at a time.

Note in particular that this heavily affects rsync, which reads and writes only one file at a time. You might try using gsutil -m rsync to transfer multiple files to or from your bucket in parallel instead of plain rsync with gcsfuse.

Rate limiting

If you would like to rate limit traffic to/from GCS in order to set limits on your GCS spending on behalf of gcsfuse, you can do so:

  • The flag --limit-ops-per-sec controls the rate at which gcsfuse will send requests to GCS.
  • The flag --limit-bytes-per-sec controls the egress bandwidth from gcsfuse to GCS.

All rate limiting is approximate, and is performed over an 8-hour window. By default, there are no limits applied.

Upload procedure control

An upload procedure is implemented as a retry loop with exponential backoff for failed requests to the GCS backend. Once the backoff duration exceeds this limit, the retry stops. Flag --max-retry-sleep controls such behavior. The default is 1 minute. A value of 0 disables retries.

GCS round trips

By default, gcsfuse uses two forms of caching to save round trips to GCS, at the cost of consistency guarantees. These caching behaviors can be controlled with the flags --stat-cache-capacity, --stat-cache-ttl and --type-cache-ttl. See semantics.md for more information.

Timeouts

If you are using FUSE for macOS, be aware that by default it will give gcsfuse only 60 seconds to respond to each file system operation. This means that if you write and then flush a large file and your upstream bandwidth is insufficient to write it all to GCS within 60 seconds, your gcsfuse file system may become unresponsive. This behavior can be tuned using the daemon_timeout mount option. See issue #196 for details.

Downloading object contents

Behind the scenes, when a newly-opened file is first modified, gcsfuse downloads the entire backing object's contents from GCS. The contents are stored in a local temporary file whose location is controlled by the flag --temp-dir. Later, when the file is closed or fsync'd, gcsfuse writes the contents of the local file back to GCS as a new object generation.

Files that have not been modified are read portion by portion on demand. gcsfuse uses a heuristic to detect when a file is being read sequentially, and will issue fewer, larger read requests to GCS in this case.

The consequence of this is that gcsfuse is relatively efficient when reading or writing entire large files, but will not be particularly fast for small numbers of random writes within larger files, and to a lesser extent the same is true of small random reads. Performance when copying large files into GCS is comparable to gsutil (see issue #22 for testing notes). There is some overhead due to the staging of data in a local temporary file, as discussed above.

Note that new and modified files are also fully staged in the local temporary directory until they are written out to GCS due to being closed or fsync'd. Therefore the user must ensure that there is enough free space available to handle staged content when writing large files.

Other performance issues

If you notice otherwise unreasonable performance, please file an issue.

Support

gcsfuse is open source software, released under the Apache license. It is distributed as-is, without warranties or conditions of any kind.

For support, visit Server Fault. Tag your questions with gcsfuse and google-cloud-platform, and make sure to look at previous questions and answers before asking a new one. For bugs and feature requests, please file an issue.

Versioning

gcsfuse version numbers are assigned according to Semantic Versioning. Note that the current major version is 0, which means that we reserve the right to make backwards-incompatible changes.

Minio: Multi-Cloud Object Storage

MinIO Quickstart Guide

MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. It is API compatible with Amazon S3 cloud storage service. Use MinIO to build high performance infrastructure for machine learning, analytics and application data workloads.

This README provides quickstart instructions on running MinIO on bare metal hardware, including container-based installations. For Kubernetes environments, use the MinIO Kubernetes Operator.

Container Installation

Use the following commands to run a standalone MinIO server as a container.

Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication require distributed deploying MinIO with Erasure Coding. For extended development and production, deploy MinIO with Erasure Coding enabled - specifically, with a minimum of 4 drives per MinIO server. See MinIO Erasure Code Quickstart Guide for more complete documentation.

Stable

Run the following command to run the latest stable image of MinIO as a container using an ephemeral data volume:

podman run -p 9000:9000 -p 9001:9001 \
  quay.io/minio/minio server /data --console-address ":9001"

The MinIO deployment starts using default root credentials minioadmin:minioadmin. You can test the deployment using the MinIO Console, an embedded object browser built into MinIO Server. Point a web browser running on the host machine to http://127.0.0.1:9000 and log in with the root credentials. You can use the Browser to create buckets, upload objects, and browse the contents of the MinIO server.

You can also connect using any S3-compatible tool, such as the MinIO Client mc commandline tool. See Test using MinIO Client mc for more information on using the mc commandline tool. For application developers, see https://docs.min.io/docs/ and click MinIO SDKs in the navigation to view MinIO SDKs for supported languages.

NOTE: To deploy MinIO on with persistent storage, you must map local persistent directories from the host OS to the container using the podman -v option. For example, -v /mnt/data:/data maps the host OS drive at /mnt/data to /data on the container.

macOS

Use the following commands to run a standalone MinIO server on macOS.

Standalone MinIO servers are best suited for early development and evaluation. Certain features such as versioning, object locking, and bucket replication require distributed deploying MinIO with Erasure Coding.

MinIO strongly recommends against using compiled-from-source MinIO servers for production environments.

Deployment Recommendations

Allow port access for Firewalls

By default MinIO uses the port 9000 to listen for incoming connections. If your platform blocks the port by default, you may need to enable access to the port.

ufw

For hosts with ufw enabled (Debian based distros), you can use ufw command to allow traffic to specific ports. Use below command to allow access to port 9000

ufw allow 9000

Below command enables all incoming traffic to ports ranging from 9000 to 9010.

ufw allow 9000:9010/tcp

firewall-cmd

For hosts with firewall-cmd enabled (CentOS), you can use firewall-cmd command to allow traffic to specific ports. Use below commands to allow access to port 9000

firewall-cmd --get-active-zones

This command gets the active zone(s). Now, apply port rules to the relevant zones returned above. For example if the zone is public, use

firewall-cmd --zone=public --add-port=9000/tcp --permanent

Note that permanent makes sure the rules are persistent across firewall start, restart or reload. Finally reload the firewall for changes to take effect.

firewall-cmd --reload

iptables

For hosts with iptables enabled (RHEL, CentOS, etc), you can use iptables command to enable all traffic coming to specific ports. Use below command to allow access to port 9000

iptables -A INPUT -p tcp --dport 9000 -j ACCEPT
service iptables restart

Below command enables all incoming traffic to ports ranging from 9000 to 9010.

iptables -A INPUT -p tcp --dport 9000:9010 -j ACCEPT
service iptables restart

Test MinIO Connectivity

Test using MinIO Console

MinIO Server comes with an embedded web based object browser. Point your web browser to http://127.0.0.1:9000 to ensure your server has started successfully.

NOTE: MinIO runs console on random port by default if you wish choose a specific port use --console-address to pick a specific interface and port.

Things to consider

MinIO redirects browser access requests to the configured server port (i.e. 127.0.0.1:9000) to the configured Console port. MinIO uses the hostname or IP address specified in the request when building the redirect URL. The URL and port must be accessible by the client for the redirection to work.

For deployments behind a load balancer, proxy, or ingress rule where the MinIO host IP address or port is not public, use the MINIO_BROWSER_REDIRECT_URL environment variable to specify the external hostname for the redirect. The LB/Proxy must have rules for directing traffic to the Console port specifically.

For example, consider a MinIO deployment behind a proxy https://minio.example.net, https://console.minio.example.net with rules for forwarding traffic on port :9000 and :9001 to MinIO and the MinIO Console respectively on the internal network. Set MINIO_BROWSER_REDIRECT_URL to https://console.minio.example.net to ensure the browser receives a valid reachable URL.

Similarly, if your TLS certificates do not have the IP SAN for the MinIO server host, the MinIO Console may fail to validate the connection to the server. Use the MINIO_SERVER_URL environment variable and specify the proxy-accessible hostname of the MinIO server to allow the Console to use the MinIO server API using the TLS certificate.

For example: export MINIO_SERVER_URL="https://minio.example.net"

DashboardCreating a bucket
DashboardDashboard

Test using MinIO Client mc

mc provides a modern alternative to UNIX commands like ls, cat, cp, mirror, diff etc. It supports filesystems and Amazon S3 compatible cloud storage services. Follow the MinIO Client Quickstart Guide for further instructions.

Upgrading MinIO

Upgrades require zero downtime in MinIO, all upgrades are non-disruptive, all transactions on MinIO are atomic. So upgrading all the servers simultaneously is the recommended way to upgrade MinIO.

NOTE: requires internet access to update directly from https://dl.min.io, optionally you can host any mirrors at https://my-artifactory.example.com/minio/

  • For deployments that installed the MinIO server binary by hand, use mc admin update
mc admin update <minio alias, e.g., myminio>

For deployments without external internet access (e.g. airgapped environments), download the binary from https://dl.min.io and replace the existing MinIO binary let's say for example /opt/bin/minio, apply executable permissions chmod +x /opt/bin/minio and proceed to perform mc admin service restart alias/.

For installations using Systemd MinIO service, upgrade via RPM/DEB packages parallelly on all servers or replace the binary lets say /opt/bin/minio on all nodes, apply executable permissions chmod +x /opt/bin/minio and process to perform mc admin service restart alias/.

Upgrade Checklist

  • Test all upgrades in a lower environment (DEV, QA, UAT) before applying to production. Performing blind upgrades in production environments carries significant risk.
  • Read the release notes for MinIO before performing any upgrade, there is no forced requirement to upgrade to latest releases upon every releases. Some releases may not be relevant to your setup, avoid upgrading production environments unnecessarily.
  • If you plan to use mc admin update, MinIO process must have write access to the parent directory where the binary is present on the host system.
  • mc admin update is not supported and should be avoided in kubernetes/container environments, please upgrade containers by upgrading relevant container images.
  • We do not recommend upgrading one MinIO server at a time, the product is designed to support parallel upgrades please follow our recommended guidelines.

Google-cloud-ruby: Google Cloud Client Library for Ruby

Google Cloud Ruby Clients

Idiomatic Ruby client libraries for Google Cloud Platform APIs.

This repository includes client libraries for Google Cloud Platform services, along with a selected set of Google services unrelated to the cloud platform.

What's here

Client library gems

Most directories each correspond to a client library RubyGem, including its code, tests, gemspec, and documentation. Some client libraries also include handwritten samples in the samples directory, and/or autogenerated samples in the snippets directory.

Most client libraries in this repository are automatically generated by the GAPIC Generator. A small number are written and maintained by hand. You can identify a generated client library by the presence of .OwlBot.yaml in the library directory. For the most part, do not try to edit generated libraries by hand, because changes will be overwritten by the code generator.

Other directories

A few directories include support files, including:

  • .github includes configuration for GitHub Actions and bots that help to maintain this repository.
  • .kokoro includes configuration for internal Google processes that help to maintain this repository.
  • .toys includes scripts for running CI, releases, and maintenance tasks.
  • acceptance and integration include shared fixtures for acceptance tests.
  • obsolete contains older libraries that are obsolete and no longer maintained.

GitHub facilities

Issues for client libraries hosted here can be filed in the issues tab. However, this is not an official support channel. If you have support questions, file a support request through the normal Google support channels, or post questions on a forum such as StackOverflow.

Pull requests are welcome. Please see the section below on contributing.

Some maintenance tasks can be run in the actions tab by authorized personnel.

Using the client libraries

These client library RubyGems each include classes and methods that can be used to make authenticated calls to specific Google APIs. Some libraries also include additional convenience code implementing common client-side workflows or best practices.

In general, you can expect to:

Activate access to the API by creating a project on the Google Cloud Console, enabling billing if necessary, and enabling the API.

Choose a library and install it, typically by adding it to your bundle. For example, here is how you might add a the Translation service client to your Gemfile:

# Gemfile

# ... previous libraries ...
gem "google-cloud-translate", "~> 3.2"

Instantiate a client object. This object represents an authenticated connection to the service. For example, here is how you might create a client for the translation service:

require "google/cloud/translate"

translation_client = Google::Cloud::Translate.translation_service

Depending on your environment and authentication needs, you might need to provide credentials to the client object.

Make API calls by invoking methods on the client. For example, here is how you might translate a phrase:

result = translation_client.translate_text contents: ["Hello, world!"],
                                           mime_type: "text/plain",
                                           source_language_code: "en-US",
                                           target_language_code: "ja-JP",
                                           parent: "projects/my-project-name"
puts result.translations.first.translated_text
# => "こんにちは世界!"

Activating the API

To access a Google Cloud API, you will generally need to activate it in the cloud console. This typically involves three steps:

If you have not created a Google Cloud Project, do so. Point your browser to the Google Cloud Console, sign up if needed, and create or choose a project. Make note of the project number (which is numeric) or project ID (which is usually three or more words separated by hyphens). Many services will require you to pass that information in when calling an API.

For most services, you will need to provide billing information. If this is your first time using Google Cloud Platform, you may be eligible for a free trial.

Enable the API you want to use. Click the "APIs & Services" tab in the left navigation, then click the "Enable APIs and Services" button near the top. Search for the API you want by name, and click "Enable". A few APIs may be enabled automatically for you, but most APIs need to be enabled explicitly.

Once you have a project set up and have enabled an API, you are ready to begin using a client library to call the API.

Choosing a client library

This repository contains two types of API client RubyGems: the main library for the API (e.g. the google-cloud-translate gem for the Translation service), and one ore more versioned libraries for different versions of the service (e.g. google-cloud-translate-v2 and google-cloud-translate-v3 for versions 2 and 3 of the service, respectively). Note that we're referring to different versions of the backend service, not of the client library gem.

In most cases, you should install the main library (the one without a service version in the name). This library will provide all the required code for making calls to the API. It may also provide additional convenience code implementing common client-side workflows or best practices. Often the main library will bring in one or more versioned libraries as dependencies, and the client and data type classes you will use may actually be defined in a versioned library, but installing the main library will ensure you have access to the best tools and interfaces for interacting with the service.

The versioned libraries are lower-level libraries that target a specific version of the service. You may choose to intall a versioned library directly, instead of or in addition to the main library, to handle advanced use cases that require lower level access.

Note: Many services may also provide client libraries with names beginning with google-apis-. Those clients are developed in a different repository, and utilize an older client technology that lacks some of the performance and ease of use benefits of the clients in the google-cloud-ruby repository. The older clients may cover some services for which a google-cloud-ruby client is not yet available, but for services that are covered, we generally recommend the clients in the google-cloud-ruby repository over the older ones.

Most client libraries have directories in this repository, or you can look up the name of the client library to use in the documentation for the service you are using. Install this library as a RubyGem, or add it to your Gemfile.

Authentication

Most API calls must be accompanied by authentication information proving that the caller has sufficient permissions to make the call. For an overview of authentication with Google, see https://cloud.google.com/docs/authentication.

These API client libraries provide several mechanisms for attaching credentials to API calls.

If your application runs on an Google Cloud Platform hosting environment such as Google Compute Engine, Google Container Engine, Google App Engine, Google Cloud Run, or Google Cloud Functions, the environment will provide "ambient" credentials which client libraries will recognize and use automatically. You can generally configure these credentials in the hosting environment, for example per-VM in Google Compute Engine.

You can also provide your own service account credentials by including a service account key file in your application's file system and setting the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path to that file. Client libraries will read this environment variable if it is set.

Finally, you can override credentials in code by setting the credentials field in the client configuration. This can be set globally on the client class or provided when you construct a client object.

See https://cloud.google.com/docs/authentication/production for more information on these and other methods of providing credentials.

Supported Ruby Versions

These libraries are currently supported on Ruby 2.6 through Ruby 3.1. Older versions of Ruby may still work, but are unsupported and not recommended.

In general, Google provides official support for Ruby versions that are actively supported by Ruby Core--that is, Ruby versions that are either in normal maintenance or in security maintenance, and not end of life. See https://www.ruby-lang.org/en/downloads/branches/ for details about the Ruby support schedule.

Library Versioning

The libraries in this repository follow Semantic Versioning.

Libraries are released at one of two different support quality levels:

GA: Libraries defined at the GA (general availability) quality level, indicated by a gem version number greater than or equal to 1.0, are stable. The code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues), or unless accompanying a semver-major version update (such as version 1.x to 2.x.) Issues and requests against GA libraries are addressed with the highest priority.

Preview: Libraries defined at a Preview quality level, indicated by a gem version number less than 1.0, are expected to be mostly stable and we're working towards their release candidate. However, these libraries may get backwards-incompatible updates from time to time. We will still address issues and requests with a high priority.

Note that the gem version is distinct from the service version. Some backend services have mulitple versions, for example versions v2 and v3 of the translation service. These are treated as separate services and will have separate versioned clients, e.g. the google-cloud-translate-v2 and google-cloud-translate-v3 gems. These gems will in turn have their own gem versions, tracking the development of the two services.

Contributing

Contributions to this repository are welcome. However, please note that many of the clients in this repository are automatically generated. The Ruby files in those clients will have a comment to that effect near the top; changes to those files will not be accepted as they will simply be overwritten by the code generator. If in doubt, please open an issue and ask the maintainers. See the CONTRIBUTING document for more information on how to get started.

Please note that this project is released with a Contributor Code of Conduct. By participating in this project you agree to abide by its terms. See Code of Conduct for more information.

Support

Please report bugs at the project on Github.

If you have questions about how to use the clients or APIs, ask on Stack Overflow.

Google-cloud-language: Ruby Client for The Cloud Natural Language API

Ruby Client for the Cloud Natural Language API

API Client library for the Cloud Natural Language API

Provides natural language understanding technologies, such as sentiment analysis, entity recognition, entity sentiment analysis, and other text annotations.

Actual client classes for the various versions of this API are defined in versioned client gems, with names of the form google-cloud-language-v*. The gem google-cloud-language is the main client library that brings the verisoned gems in as dependencies, and provides high-level methods for constructing clients. More information on versioned clients can be found below in the section titled Which client should I use?.

View the Client Library Documentation for this library, google-cloud-language, to see the convenience methods for constructing client objects. Reference documentation for the client objects themselves can be found in the client library documentation for the versioned client gems: google-cloud-language-v1, google-cloud-language-v1beta2.

See also the Product Documentation for more usage information.

Quick Start

$ gem install google-cloud-language

In order to use this library, you first need to go through the following steps:

  1. Select or create a Cloud Platform project.
  2. Enable billing for your project.
  3. Enable the API.
  4. {file:AUTHENTICATION.md Set up authentication.}

Migrating from 0.x versions

The 1.0 release of the google-cloud-language client is a significant upgrade based on a next-gen code generator, and includes substantial interface changes. Existing code written for earlier versions of this library will likely require updates to use this version. See the {file:MIGRATING.md MIGRATING.md} document for more information.

Enabling Logging

To enable logging for this library, set the logger for the underlying gRPC library. The logger that you set may be a Ruby stdlib Logger as shown below, or a Google::Cloud::Logging::Logger that will write logs to Cloud Logging. See grpc/logconfig.rb and the gRPC spec_helper.rb for additional information.

Configuring a Ruby stdlib logger:

require "logger"

module MyLogger
  LOGGER = Logger.new $stderr, level: Logger::WARN
  def logger
    LOGGER
  end
end

# Define a gRPC module-level logger method before grpc/logconfig.rb loads.
module GRPC
  extend MyLogger
end

Supported Ruby Versions

This library is supported on Ruby 2.6+.

Google provides official support for Ruby versions that are actively supported by Ruby Core—that is, Ruby versions that are either in normal maintenance or in security maintenance, and not end of life. Older versions of Ruby may still work, but are unsupported and not recommended. See https://www.ruby-lang.org/en/downloads/branches/ for details about the Ruby support schedule.

Which client should I use?

Most modern Ruby client libraries for Google APIs come in two flavors: the main client library with a name such as google-cloud-language, and lower-level versioned client libraries with names such as google-cloud-language-v1. In most cases, you should install the main client.

What's the difference between the main client and a versioned client?

A versioned client provides a basic set of data types and client classes for a single version of a specific service. (That is, for a service with multiple versions, there might be a separate versioned client for each service version.) Most versioned clients are written and maintained by a code generator.

The main client is designed to provide you with the recommended client interfaces for the service. There will be only one main client for any given service, even a service with multiple versions. The main client includes factory methods for constructing the client objects we recommend for most users. In some cases, those will be classes provided by an underlying versioned client; in other cases, they will be handwritten higher-level client objects with additional capabilities, convenience methods, or best practices built in. Generally, the main client will default to a recommended service version, although in some cases you can override this if you need to talk to a specific service version.

Why would I want to use the main client?

We recommend that most users install the main client gem for a service. You can identify this gem as the one without a version in its name, e.g. google-cloud-language. The main client is recommended because it will embody the best practices for accessing the service, and may also provide more convenient interfaces or tighter integration into frameworks and third-party libraries. In addition, the documentation and samples published by Google will generally demonstrate use of the main client.

Why would I want to use a versioned client?

You can use a versioned client if you are content with a possibly lower-level class interface, you explicitly want to avoid features provided by the main client, or you want to access a specific service version not be covered by the main client. You can identify versioned client gems because the service version is part of the name, e.g. google-cloud-language-v1.

What about the google-apis- clients?

Client library gems with names that begin with google-apis- are based on an older code generation technology. They talk to a REST/JSON backend (whereas most modern clients talk to a gRPC backend) and they may not offer the same performance, features, and ease of use provided by more modern clients.

The google-apis- clients have wide coverage across Google services, so you might need to use one if there is no modern client available for the service. However, if a modern client is available, we generally recommend it over the older google-apis- clients.

serviço baseado em nuvemhttps://litslink.com/blog/iaas-paas-saas

IaaS

Essencialmente, esta é uma versão virtual de um data center físico. Os provedores de infraestrutura em nuvem usam a tecnologia de virtualização para fornecer recursos de computação escaláveis ​​a seus clientes, incluindo servidores, redes e armazenamento. Os clientes se beneficiam disso, pois não podem comprar hardware pessoal e gerenciar seus componentes. Em vez de implantar seus aplicativos e plataformas em data centers físicos, eles podem usar as máquinas virtuais do provedor. O provedor de IaaS gerencia toda a infraestrutura, mas os usuários a controlam totalmente. Aplicativos e sistemas operacionais são instalados e mantidos pelos usuários, assim como segurança, tempo de execução, middleware e dados.

Vantagens do IaaS:

1. Modelo com maior flexibilidade e potencial dinâmico.

2. Devido ao preço de pagamento conforme o uso, é econômico.

3. A implantação automatizada de hardware facilita o uso.

O software SaaS pode ser acessado pela web por meio de APIs e está localizado em uma rede de nuvem distante. Os clientes podem trabalhar juntos em projetos, armazenar dados e analisá-los com esses aplicativos.

O tipo mais popular de computação em nuvem é o SaaS. Tudo, desde a estabilidade do hardware até a funcionalidade do aplicativo, é gerenciado pelo provedor de SaaS. Nesse arranjo, os clientes são exclusivamente responsáveis ​​pelo uso de programas para realizar seus trabalhos. Nesse caso, o provedor controla a experiência de software do cliente.

Vantagens do SaaS:

1. Não há custos de hardware e os custos de configuração inicial não são incorridos.

2. As atualizações são realizadas automaticamente.

3. Adaptabilidade a vários dispositivos.

4. Facilmente acessível de qualquer lugar, Um modelo de pagamento por uso.

5. Adaptabilidade, a personalização é fácil.

Desvantagens do SaaS:

1. A falta de controle.

2. As soluções são limitadas.

3. A necessidade de conectividade não pode ser exagerada.

さまざまな種類のクラウドベースのサービス

クラウド コンピューティングは、今日最も急速に成長している IT テクノロジの 1 つです。2025 年までに、エンタープライズ ワークロードの 83% がクラウドになります。IDC のレポートによると、世界は 2018 年にクラウド サービスとインフラストラクチャに 1,600 億ドルを費やすと予測されています。クラウドには、さまざまなオンライン サービスが含まれます。クラウド サービスを検討している企業は、IaaS、PaaS、SaaS の違いを理解することが重要です。ビジネス要件と、委任または自分で処理するタスクの数に応じて、適切なモデルを選択する必要があります。理想的なクラウド サービスを選択することは間違いなく困難であり、決定する前にいくつかの要因を検討する必要があります。ここでは、SaaS、PaaS、および IaaS のすべての利点と欠点を取り上げ、どのモデルが会社に最適かを判断するのに役立てました。

クラウドベースのサービスhttps://litslink.com/blog/iaas-paas-saas

IaaS

基本的に、これは物理データ センターの仮想バージョンです。クラウド インフラストラクチャ プロバイダーは、仮想化テクノロジを使用して、サーバー、ネットワーク、ストレージなどのスケーラブルなコンピューティング リソースをクライアントに提供します。クライアントは、個人のハードウェアを購入してそのコンポーネントを管理することができないため、このメリットを享受できます。アプリケーションとプラットフォームを物理データ センターに展開する代わりに、プロバイダーの仮想マシンを使用できます。IaaS プロバイダーはインフラストラクチャ全体を管理しますが、ユーザーはそれを完全に制御します。アプリとオペレーティング システムは、セキュリティ、ランタイム、ミドルウェア、およびデータと同様に、ユーザーによってインストールおよび維持されます。

IaaS の利点:

1. 最大限の柔軟性とダイナミックな可能性を備えたモデル。

2. 従量課金制のため、コストパフォーマンスに優れています。

3. 自動化されたハードウェア展開により、使いやすくなります。

4. 管理タスクが仮想化されるため、従業員は他のタスクにより多くの時間を割くことができます。

IaaS の欠点:

1. マルチテナント アーキテクチャはセキュリティ リスクをもたらします。

2. ベンダーの停止により、顧客はしばらくデータにアクセスできません。

3. 新しいインフラストラクチャを管理する方法を学ぶには、チームのトレーニングが必要です。

PaaS

PaaS (Platform as a Service) は、ソフトウェアを作成するためのインターネット ベースのフレームワークです。このプラットフォームには、開発者がアプリケーションの作成、カスタマイズ、テスト、起動に使用できるソフトウェア コンポーネントとツールが含まれています。PaaS のベンダーは、サーバー、オペレーティング システムの更新プログラム、セキュリティ パッチ、およびバックアップを管理します。アプリ開発者とデータ管理者は、インフラストラクチャ、ミドルウェア、およびオペレーティング システムの維持について心配する必要はありません。IaaS と PaaS の主な違いは、ユーザーに与えられる制御の範囲です。

PaaS の利点:

1. PaaS で構築されたソフトウェアはクラウドベースであるため、拡張性、可用性、マルチテナント性に優れています。

2. 開発プロセスの合理化とスピードアップ。

3. アプリの作成、テスト、および起動のコストが削減されます。

4. ポリシーの自動化。

5. 必要なコーディング量の削減。

PaaS の欠点:

1. データのセキュリティに関する問題。

2. 既存のインフラストラクチャのすべての要素をクラウド対応にすることはできません。

3. 速度、信頼性、サポートはベンダーによって異なります。

SaaS

ベンダーは、このオファリングでクラウドベースのソフトウェアを提供します。SaaS アプリケーションをダウンロードしてローカル デバイスにインストールする必要はありませんが、プラグインが必要になる場合があります。SaaS ソフトウェアは、Web 経由で API を介してアクセスでき、離れたクラウド ネットワーク上に配置されます。顧客はこれらのアプリを使用して、プロジェクトで共同作業し、データを保存し、分析することができます。

クラウド コンピューティングの最も一般的なタイプは SaaS です。ハードウェアの安定性からアプリの機能まで、すべてが SaaS プロバイダーによって管理されます。この取り決めでは、クライアントは、プログラムを使用して自分の仕事を実行する責任を独占的に負います。この場合、プロバイダーはクライアントのソフトウェア エクスペリエンスを制御します。

SaaS の利点:

1. ハードウェアの費用がかからず、初期設定費用も発生しません。

2. アップグレードは自動的に実行されます。

3. 複数のデバイスへの適応性。

4. どこからでも簡単にアクセスできる従量制モデル。

5. 適応性、カスタマイズは容易です。

SaaS の欠点:

1. コントロールの欠如。

2. ソリューションは限られています。

3. コネクティビティの必要性はいくら強調してもしすぎることはありません。

IaaS

Il s'agit essentiellement d'une version virtuelle d'un centre de données physique. Les fournisseurs d'infrastructure cloud utilisent la technologie de virtualisation pour fournir des ressources informatiques évolutives à leurs clients, notamment des serveurs, des réseaux et du stockage. Les clients en bénéficient car ils ne peuvent pas acheter de matériel personnel et gérer ses composants. Au lieu de déployer leurs applications et plates-formes dans des centres de données physiques, ils peuvent utiliser les machines virtuelles du fournisseur. Le fournisseur IaaS gère l'ensemble de l'infrastructure, mais les utilisateurs la contrôlent entièrement. Les applications et les systèmes d'exploitation sont installés et maintenus par les utilisateurs, ainsi que la sécurité, l'exécution, le middleware et les données.

Avantages du IaaS :

1. Modèle avec la plus grande flexibilité et potentiel dynamique.

2. En raison de la tarification à l'utilisation, il est rentable.

3. Le déploiement automatisé du matériel facilite son utilisation.

4. Les employés ont plus de temps pour d'autres tâches car les tâches de gestion sont virtualisées.

Inconvénients du IaaS :

1. L'architecture mutualisée présente des risques de sécurité.

2. Les clients ne peuvent pas accéder à leurs données pendant un certain temps en raison de pannes de fournisseurs.

3. Apprendre à gérer une nouvelle infrastructure nécessite une formation d'équipe.

PaaS

PaaS, ou Platform as a Service, est un cadre basé sur Internet pour la création de logiciels. Cette plate-forme contient des composants logiciels et des outils que les développeurs peuvent utiliser pour créer, personnaliser, tester et lancer des applications. Les fournisseurs de PaaS gèrent les serveurs, les mises à jour du système d'exploitation, les correctifs de sécurité et les sauvegardes. Les développeurs d'applications et les gestionnaires de données n'ont pas à se soucier de la maintenance de l'infrastructure, du middleware et des systèmes d'exploitation. IaaS et PaaS diffèrent principalement par le degré de contrôle accordé aux utilisateurs.

Avantages du PaaS :

1. Étant donné que le logiciel PaaS est basé sur le cloud, il est hautement évolutif, disponible et multi-locataire.

SaaS

Le fournisseur fournit un logiciel basé sur le cloud avec cette offre. Les applications SaaS n'ont pas besoin d'être téléchargées et installées sur des appareils locaux, mais des plug-ins peuvent parfois être nécessaires. Le logiciel SaaS est accessible via le Web via des API et est situé sur un réseau cloud distant. Les clients peuvent travailler ensemble sur des projets, stocker des données et les analyser avec ces applications.

Le type de cloud computing le plus populaire est le SaaS. Tout, de la stabilité du matériel à la fonctionnalité de l'application, est géré par le fournisseur SaaS. Dans cet arrangement, les clients sont exclusivement responsables de l'utilisation des programmes pour effectuer leur travail. Dans ce cas, le fournisseur contrôle l'expérience logicielle du client.

Avantages du SaaS :

1. Il n'y a pas de frais de matériel et les frais d'installation initiaux ne sont pas encourus.

2. Les mises à niveau sont effectuées automatiquement.

3. Adaptabilité à plusieurs appareils.

4. Facilement accessible de n'importe où, un modèle de paiement à l'utilisation.

5. Adaptabilité, la personnalisation est facile.

Inconvénients du SaaS :

1. Un manque de contrôle.

2. Les solutions sont limitées.

3. Le besoin de connectivité ne peut être surestimé.

Các Loại Dịch Vụ của Cloud-based Services

Điện toán đám mây là một trong những công nghệ CNTT phát triển nhanh nhất hiện nay. Đến năm 2025, 83% khối lượng công việc của doanh nghiệp sẽ là trên đám mây. Theo báo cáo của IDC, thế giới sẽ chi 160 tỷ USD cho các dịch vụ và cơ sở hạ tầng đám mây vào năm 2018. Đám mây bao gồm nhiều loại dịch vụ trực tuyến. Điều quan trọng đối với các doanh nghiệp đang xem xét dịch vụ đám mây là phải hiểu sự khác biệt giữa IaaS, PaaS và SaaS. Bạn nên chọn mô hình phù hợp tùy thuộc vào yêu cầu kinh doanh của bạn và số lượng nhiệm vụ bạn muốn ủy thác hoặc tự xử lý. Việc lựa chọn dịch vụ đám mây lý tưởng chắc chắn là rất khó và bạn phải cân nhắc một số yếu tố trước khi quyết định. Ở đây, chúng tôi đã đề cập đến tất cả những lợi ích và hạn chế của SaaS, PaaS và IaaS để giúp bạn quyết định mô hình nào phù hợp nhất cho công ty của bạn.

dịch vụ dựa trên đám mâyhttps://litslink.com/blog/iaas-paas-saas

IaaS

Về cơ bản, đây là một phiên bản ảo của một trung tâm dữ liệu vật lý. Các nhà cung cấp cơ sở hạ tầng đám mây sử dụng công nghệ ảo hóa để cung cấp các tài nguyên máy tính có thể mở rộng cho khách hàng của họ, bao gồm máy chủ, mạng và bộ nhớ. Khách hàng được hưởng lợi từ điều này vì họ không thể mua phần cứng cá nhân và quản lý các thành phần của nó. Thay vì triển khai các ứng dụng và nền tảng của họ trong các trung tâm dữ liệu vật lý, họ có thể sử dụng các máy ảo của nhà cung cấp. Nhà cung cấp IaaS quản lý toàn bộ cơ sở hạ tầng, nhưng người dùng hoàn toàn kiểm soát nó. Các ứng dụng và hệ điều hành được cài đặt và duy trì bởi người dùng, cũng như bảo mật, thời gian chạy, phần mềm trung gian và dữ liệu.

Ưu điểm của IaaS:

1. Mô hình có tính linh hoạt và tiềm năng động lớn nhất.

2. Do giá cả phải trả khi bạn di chuyển, nó là hiệu quả về chi phí.

3. Triển khai phần cứng tự động giúp bạn dễ dàng sử dụng.

4. Nhân viên có nhiều thời gian hơn cho các nhiệm vụ khác vì các nhiệm vụ quản lý được ảo hóa.

Nhược điểm của IaaS:

1. Kiến trúc đa đối tượng gây ra rủi ro bảo mật.

2. Khách hàng không thể truy cập dữ liệu của họ trong một thời gian do nhà cung cấp ngừng hoạt động.

3. Học cách quản lý cơ sở hạ tầng mới yêu cầu đào tạo nhóm.

PaaS

PaaS, hoặc Nền tảng dưới dạng Dịch vụ, là một khuôn khổ dựa trên internet để tạo phần mềm. Nền tảng này chứa các thành phần phần mềm và công cụ mà nhà phát triển có thể sử dụng để tạo, tùy chỉnh, kiểm tra và khởi chạy ứng dụng. Nhà cung cấp PaaS quản lý máy chủ, cập nhật hệ điều hành, bản vá bảo mật và bản sao lưu. Các nhà phát triển ứng dụng và quản lý dữ liệu không phải lo lắng về việc duy trì cơ sở hạ tầng, phần mềm trung gian và hệ điều hành. IaaS và PaaS chủ yếu khác nhau về mức độ kiểm soát của người dùng.

Ưu điểm của PaaS:

1. Vì phần mềm do PaaS xây dựng dựa trên nền tảng đám mây nên nó có khả năng mở rộng cao, khả dụng và nhiều người thuê.

2. Hợp lý hóa và đẩy nhanh quá trình phát triển.

3. Giảm chi phí tạo, thử nghiệm và khởi chạy ứng dụng.

4. Tự động hóa chính sách.

5. Giảm số lượng mã hóa cần thiết.

Nhược điểm của PaaS:

1. Các vấn đề liên quan đến bảo mật dữ liệu.

2. Không thể kích hoạt đám mây mọi yếu tố của cơ sở hạ tầng hiện có.

3. Tốc độ, độ tin cậy và hỗ trợ tùy thuộc vào nhà cung cấp.

SaaS

Nhà cung cấp cung cấp phần mềm dựa trên đám mây với dịch vụ này. Các ứng dụng SaaS không cần được tải xuống và cài đặt trên các thiết bị cục bộ, nhưng thỉnh thoảng có thể cần các plugin. Phần mềm SaaS có thể được truy cập qua web thông qua các API và được đặt trên một mạng đám mây ở xa. Khách hàng có thể làm việc cùng nhau trong các dự án, lưu trữ và phân tích dữ liệu bằng các ứng dụng này.

Loại điện toán đám mây phổ biến nhất là SaaS. Mọi thứ, từ độ ổn định của phần cứng đến chức năng của ứng dụng, đều do nhà cung cấp SaaS quản lý. Trong thỏa thuận này, khách hàng chịu trách nhiệm độc quyền về việc sử dụng các chương trình để thực hiện công việc của họ. Trong trường hợp này, nhà cung cấp kiểm soát trải nghiệm phần mềm của khách hàng.

Ưu điểm của SaaS:

1. Không có chi phí phần cứng và không phát sinh chi phí thiết lập ban đầu.

2. Nâng cấp được thực hiện tự động.

3. Khả năng thích ứng với nhiều thiết bị.

4. Dễ dàng truy cập từ mọi nơi, Mô hình trả tiền cho mỗi lần sử dụng.

5. Khả năng thích ứng, Tùy chỉnh rất dễ dàng.

Nhược điểm của SaaS:

1. Sự thiếu kiểm soát.

2. Các giải pháp còn hạn chế.

3. Nhu cầu kết nối không thể được phóng đại.

A Julia interface to The Plot.ly Plotting Library & Cloud Services

Plotly.jl

A Julia interface to the plot.ly plotting library and cloud services

Install

Simply run Pkg.add("Plotly").

Usage

Plotting functions provided by this package are identical to PlotlyJS. Please consult its documentation. In fact, the package depends on PlotlyJS.jl and reexports all the methods.

For example, this will display a basic scatter plot:

my_plot = plot([scatter(x=[1,2], y=[3,4])], Layout(title="My plot"))

Using the Plotly cloud

New user signup

Find your username and API key in the Plotly settings.

Signin

julia> Plotly.signin("username","your api key")
PlotlyAccount("username","your api key")

Note: you may also specify your session endpoints using sign in as follows:

julia> Plotly.signin("username","your api key",Dict("plotly_domain"=> "your_plotly_base_endpoint", "plotly_api_domain"=> "your_plotly_api_endpoint"))

Saving your credentials

julia> Plotly.set_credentials_file(Dict("username"=>"your_user_name","api_key"=>"your_api_key"))

Note: your credentials will be saved within /YOUR_HOME_DIR/.plotly/.credentials

Saving your endpoint configuration

julia> Plotly.set_config_file(Dict("plotly_domain"=> "your_plotly_base_endpoint", "plotly_api_domain"=> "your_plotly_api_endpoint"))

Note: your configuration will be saved within /YOUR_HOME_DIR/.plotly/.config

Saving a plot to the cloud

Use the post function to upload a local plot to the Plotly cloud:

> my_plot  = plot([scatter(y=[1,2])])
> remote_plot = post(my_plot)
Plotly.RemotePlot(URI(https://plot.ly/~malmaud/73))

Visiting https://plot.ly/~malmaud/73 in a browser will show the plot.

Download a plot from the cloud

Use the download function with a remote plot object to download a plot stored on the Plotly cloud to a local Plot object:

local_plot = download(RemotePlot("https://plot.ly/~malmaud/73"))
# or equivalently, local_plot = download_plot("https://plot.ly/~malmaud/73")

Working with plotlyjs() backend of Plots.jl

A plot created by Plots.jl with plotlyjs() backend has the type Plot{Plots.PlotlyJSBackend()}. To use the Plotly.jl interfeces, the plot object needs to be converted by

my_plot = Plots.plotlyjs_syncplot(plots_plot)

The object my_plot can be handed to the Cloud API descrived above.

Acknowledgements

PlotlyJS.jl , which provides the large majority of the functionality of this package, is developed primarily by Spencer Lyon.

This package, which adds to PlotlyJS.jl the functionality for interacting with the Plotly cloud, is developed by Jon Malmaud and others.
