In a simple way, we can say DevOps is made up of two terms, one development and the other operational. When both join together, it is called DevOps.
Basically, DevOps is the only term capable of managing the entire application lifecycle, from development to testing, deployment and operations.
Suppose a company has to deploy an application, earlier it used to be that, the developer must first write the code.
After writing the code, he had to do environment setup and testing.
We can say that when DevOps was not introduced, the developer had to do all the work from writing the code to deploying the code.
Whether setting up the environment or doing unit tests, the developer had to do it all alone.
But with the advent of Devops, things became much easier. The developer's work is reduced from writing the code to committing the code.
Subsequent tasks such as setting up the environment for the application, running the application in a test environment and doing a unit test provided by the developer and at last deploying the application in production all come under DevOps list.
By dividing this entire work between the developer and DevOps, things have become very easy.
Developers can work well on their code quality and DevOps can concentrate on the deployment process.
