Why You Should Consider Database-as-a-Service

Let’s say you’re kicking off a project, maybe it’s an app, data store, IoT project, etc. No matter what you’re building, you will almost always need a database, the foundation of most applications. While this initial decision is easy, it gets infinitely more complicated from there.

What kind of database do I need? Where do I put it? How many do I need? Why am I doing this to myself? Ahhhh, this was supposed to be a simple project!

Enter Database-as-a-Service (DBaaS), where you don’t have to worry about managing installation, configuration, maintenance, IT staffing, or anything else that comes with running a database in-house. Many database vendors offer DBaaS as a quick, easy, secure, and cost effective way to get your project up and running. Database-as-a-Service runs in the cloud and is definitely something you should consider, and this blog will discuss some of the reasons why.

Simplicity

First, and most importantly, DBaaS is simple. The simplicity of clicking a button to spin up a database instance cannot be beat. All you need to do is put in a credit card (some even offer free tiers, so skip this step), set a couple instance parameters, and click go. You’ll have a fully functional database instance in a couple minutes. That’s called rapid provisioning, and it’s awesome.

Effectively you’re outsourcing the database configuration and administration to the people who know how to do it best, usually the company that built the database in the first place. Many service providers include or offer backups, recovery, tuning, optimization, patching, and upgrading. This allows you or your team to focus on what you know best: the application. Get rid of the headaches of on-premises hosting and spin up a DBaaS database in minutes.

Costs

If your boss isn’t so keen on the idea of outsourcing, the ability to cut costs may get his or her attention. DBaaS models are typically significantly less expensive than their on-premise alternatives. There’s no need for IT staff to deploy, manage, upgrade, or maintain the database and the hardware it would run on, all of that is bundled into the price of the instance. This typically leads to a reduction in downtime, which leads to improved customer satisfaction.

That may not be explicitly calculated into cost, but it is usually reflected in revenue. The best part of paying for DBaaS is that they follow a pay-per-use model, so you’re only paying for exactly what you’re using. If you spin up a few extra instances for a month of testing, you’ll only pay extra in that monthly fee. Forget about software license costs and concerns because it’s all taken care of with DBaaS.

Security

You may be wondering about security. What happens when I let data out of my control? It’s a valid concern. Ultimately the best security is to never put data online in the first place, but that’s just plain unrealistic. Cloud providers are now quite good at ensuring that your data is secured. DBaaS providers offer strong, configurable firewall rules allowing you to expose your data where you want it, and only where you want it.

Communication will most likely take place over a secured protocol like HTTPS, SSL, etc. Practically every database I’ve ever come across has user access controls, configurable users and roles, or some sort of security protocol required to access any data. My favorite security fact is that DBaaS providers typically utilize large data centers either provided by themselves or the larger cloud providers like Amazon Web Services. Their data centers are some of the most physically secure facilities on the planet.

Secured 24/7, 365 days a year. While physical security is often overlooked in technology, you can rest assured that it’s covered. Security is vital in any as-a-Service business and companies do everything they can to ensure your data is secure.

Scalability

Along the lines of the pay-per-use model, scalability is one of the major benefits of using a Database-as-a-Service. With just a bit of administration, usually by clicking around in a management console of some sort, you can scale your database or databases. Vertical scaling is as simple as increasing RAM, processors, storage space, etc., just by incrementing some numbers.

Give the instance a few minutes to reprovision and just like that you’ll have a more powerful database. When it comes to horizontal scaling, it’s as simple as spinning up more instances. Rapid provisioning here we come! Many databases offer clustering configurations allowing multiple instances to work in conjunction with each other. Ideally, the management studio allows users to connect various instances as part of the cluster. Again, you’ll quickly have a horizontally scaled database platform without having to leave your browser.

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

Master
Model
MSDB
Tempdb
Resource

Master

This database contains all the System level Information in SQL Server. The Information in form of Meta data.
Because of this master database, we are able to access the SQL Server (On premise SQL Server)

Model

This database is used as a template for new databases.
Whenever a new database is created, initially a copy of model database is what created as new database.

MSDB

This database is where a service called SQL Server Agent stores its data.
SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.

TempDB

The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
User can create their own version of temporary tables and those are stored in Tempdb.
But this database is destroyed and recreated every time when we restart the instance of SQL Server.

Resource

The resource database is a hidden, read only database that holds the definitions of all system objects.
When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

Django-allauth: A simple Boilerplate to Setup Authentication

Django-Authentication

A simple Boilerplate to Setup Authentication using Django-allauth, with a custom template for login and registration using django-crispy-forms.

Getting Started

Prerequisites

Python 3.8.6 or higher

Project setup

# clone the repo
$ git clone https://github.com/yezz123/Django-Authentication

# move to the project folder
$ cd Django-Authentication

Creating virtual environment

Create a virtual environment for this project:

# creating pipenv environment for python 3
$ virtualenv venv

# activating the pipenv environment
$ cd venv/bin #windows environment you activate from Scripts folder

# if you have multiple python 3 versions installed then
$ source ./activate

Configured Enviromment

Environment variables

SECRET_KEY = #random string
DEBUG = #True or False
ALLOWED_HOSTS = #localhost
DATABASE_NAME = #database name (You can just use the default if you want to use SQLite)
DATABASE_USER = #database user for postgres
DATABASE_PASSWORD = #database password for postgres
DATABASE_HOST = #database host for postgres
DATABASE_PORT = #database port for postgres
ACCOUNT_EMAIL_VERIFICATION = #mandatory or optional
EMAIL_BACKEND = #email backend
EMAIL_HOST = #email host
EMAIL_HOST_PASSWORD = #email host password
EMAIL_USE_TLS = # if your email use tls
EMAIL_PORT = #email port

change all the environment variables in the .env.sample and don't forget to rename it to .env.

Run the project

After Setup the environment, you can run the project using the Makefile provided in the project folder.
