DevOps

What is DevOps ?

DevOps is a culture wherein the Operations team combine to work directly with the developing team to build high scaling application at a faster pace. DevOps --> Developing Team + Operations Team combined together through various tools to deliver application(s).

Why DevOps ?

Operations team typically build, generate required jar/war files and move it across the testing and production environment(s). By implementing DevOps, we can able to reduce the time spent for Building, segregating war files, avoid human error(s) while moving the file(s) across the server(s). In other words DevOps is a one time implementation process which can automate the work of Operation team.

DevOps Model:

DevOps Terms:

Dev Team --> Plan, Code, Build, Test

Ops Team --> Release, Deploy, Operate, Monitor.

Continuous Integration : A Software development practice where developers regularly merge their code changes into a central repository, after which automated builds and tests are run. The key goals of continuous integration are to find and address bugs quicker, improve software quality, and reduce the time it takes to validate and release new software updates.

Continuous Delivery : A software development practice where code changes are automatically built, tested, and prepared for a release to production.

Need for DevOps ?

First and foremost thing to note is the number of release cycles your organization is having per Sprint / week. In case if the Demand > Supply and your Operations teams is struggling to do "N" number of deployments then implementing DevOps will be a better option to maintain Demand == Supply. In this fast paced world, where updates & requirements from the customer(s) are increasing day by day larger scale companies who have implemented DevOps are seeing the fruit daily. Imagine you need to deploy an application in production typically it will take minimum an hour and may extend depends on the complexity of the server. If this is the case, whenever there is a commit in a central repo, your application will build, deploy in the prod and do a sanity and send you the results in mail. Magical isn't it? Well if your eyes got enlarged hearing this, welcome to DevOps.

How to Implement DevOps ?

There are various way to implement DevOps in your organization. For better understanding, I am trying to explain in a easy way.

Integration is the primary thing we need to do while implementing DevOps.

Central Repo(GitHub) + Build environment(Jenkins) + Containerization(Dockers) + Deploying server(AWS) + Automation Testing(Selenium) --> DevOps

Do you know? Amazon engineers deploy code every 11.7 seconds, on average.

Pros - DevOps:

Speed, Rapid Delivery, Reliability, Scale, Improved Collaboration, Security.

Then, Why wait? Try to understand the need for your organization and if this practice helps, well you know what you need to do :)
