Ansible with AWS and EC2 - DZone DevOps

A few months ago, I did some RnD tasks using ansible at VizuaMatix. After that I didn’t use Ansible for anything useful, today I got a YouTube suggestion for ansible again. After watching it I thought, I should get my hands dirty again with Ansible. I decided to do some Ansible tasks using AWS EC2.

For this, I have used a master node and a worker node. Both running Ubuntu 18.04.4 And the task was very simple. Install the VLC media player in our worker node, and then removing it.


First thing first, we must have Ansible installed in master and worker/s. To install just use :

sudo apt install ansible

Then we need to share our master’s public-key to worker/s. We create a ssh key from the master node and share it with worker node/s.

ssh-keygen -t rsa -N “” -f /home/ubuntu/.ssh/id_rsa

Then cat and copy the content cat .ssh/id_rsa.pub

Go to worker/s terminal and vim ~/.ssh/authorized_keys paste the content at the bottom of this file, save and exit. This step was explained here.

and check the connectivity, from master node try :

If our key sharing is successful, then you should be able to login to the worker node without any password.

Then let’s add our worker node/s to ansible. In master node, open /etc/ansible/hosts the file and add a group to it. Here I have named it as [workers] . Now onward, when you specify workers in your playbook, ansible knows what hosts to use when running the playbook.

[workers]

Save and then let’s try to ping our worker node/s : ansible workers -m ping

How to Extend your DevOps Strategy For Success in the Cloud?

DevOps and Cloud computing are joined at the hip, now that fact is well appreciated by the organizations that engaged in SaaS cloud and developed applications in the Cloud. During the COVID crisis period, most of the organizations have started using cloud computing services and implementing a cloud-first strategy to establish their remote operations. Similarly, the extended DevOps strategy will make the development process more agile with automated test cases.

According to the survey in EMEA, IT decision-makers have observed a 129%* improvement in the overall software development process when performing DevOps on the Cloud. This success result was just 81% when practicing only DevOps and 67%* when leveraging Cloud without DevOps. Not only that, but the practice has also made the software predictability better, improve the customer experience as well as speed up software delivery 2.6* times faster.

3 Core Principle to fit DevOps Strategy

If you consider implementing DevOps in concert with the Cloud, then the

below core principle will guide you to utilize the strategy.

  • It is indispensable to follow a continuous process, including all stages from Dev to deploy with the help of auto-provisioning resources of the target platform.
  • The team always keeps an eye on major and minor application changes that can typically appear within a few hours of development to operation. However, the support of unlimited resource provisioning is needed at the stage of deployment.
  • Cloud or hybrid configuration can associate this process, but you must confirm that configuration should support multiple cloud brands like Microsoft, AWS, Google, any public and private cloud models.

Guide to Remold Business with DevOps and Cloud

Companies are now re-inventing themselves to become better at sensing the next big thing their customers need and finding ways with the Cloud based DevOps to get ahead of the competition.

A Beginner's Guide to Amazon EC2 (Elastic Compute Cloud)

Amazon EC2 is a service that allows you businesses to run their application in AWS cloud. You can easily set up a virtual machine and perform all your computation on it. In this post, we will teach you the basics of Amazon EC2.

Introduction

EC2 is one of the oldest and fundamental services of AWS. Though everything today is serverless, you still need to know EC2. EC2 allows you to do the following things :

  • Rent virtual machines (EC2 itself)
  • Store data on virtual drives (EBS)
  • Distribute load across the machines (ELB)
  • Scale the services using an auto-scaling group (ASG)

Amazon Machine Image – AMI

AMIs are the templates from which virtual servers (EC2 instance) get created.

In simple terms, AMIs are the collection of the operating system, architecture (32-bit or 64-bit) with the softwares that will be running on that operating system.

For example:

  • Amazon Linux AMI is the one that comes with a Linux operating system and many packages of the Linux that one might need.

  • Windows AMI comes with Windows as its operating system and software one might need.

By choosing AMI you basically decide the software part of your EC2 machine. You can use a single AMI and launch multiple instances from it.

The Shift of Winds from CI- Pipelines to DevOps Assembly Lines in 2020

The trends show the interests of the IT industry in CI as the only tool for deployments is slowing down. Continuous Integration (CI) is the process that automates build and runs unit tests on each PUSH of code. CI-Pipelines only work in segments. In order for all the teams to collaborate better, there is a need for automation of CI along with Continuous Delivery and Continuous Deployment of the code and binaries to the target environments. That is where DevOps comes into the picture to improve the process of planning, coding, and automation of delivery and deployment.

Embedded Security on Top of List

Cyber security is one of the vital concerns for IT corporations. DevOps is going to be spending a lot of resources on security. The term being used is DevSecOps. The increase in the need for security has made the integration of security in the application development process necessary. By this measure, the vulnerabilities will decrease, and the whole process will be effective, secure, and efficient.

Need for Server-Less Architecture

There will be a simplification of operations with the server-less architecture used by DevOps teams. Legacy systems are being upgraded to server-less operations with solutions like Google Functions, AWS Lambda, and Microsoft’s Azure Functions. This change is cost-effective and also improves the experience of users. This server-less architecture will be the go-to architecture for developers to increase productivity and will need DevOps automation more than ever.

The Future Is Zero-Touch Automation

Zero-touch automation is the future of DevOps automation. There will be no need for human intervention when machine learning is utilized to automate the back-up of vast data fully. The companies which have already implemented or adapted DevOps have seen a significant increase in productivity and faster rates of deployment. Understanding the DevOps cycle and administering automation between all the blocks of sequences.

Shift to Cloud-Native DevOps

There will be an accelerated shift to Cloud-native DevOps since all the enterprises are moving to Cloud-based enterprise products. Cloud adoption ensures flexibility, less downtime, reduces infrastructure expenditures. Gartner predicts that shift to the cloud by 2022 will effect 1.3 Trillion USD of IT industry spending directly or indirectly. Many companies like Google, Microsoft, and Amazon provide cloud computing and storage facilities and smooth operations. These companies are seeing a massive spike in other enterprises looking for their cloud services for faster changes in production.
