Lession - #1505 DevOps Pipeline Methodology


What's a DevOps Pipeline?

A DevOps pipeline is a set of practices that the development( Dev>
and operations( Ops>
teams implement to build, test, and deploy software faster and easier. One of the primary purposes of a pipeline is to keep the software development process organized and focused.

The term" pipeline" might be a bit misleading, however. An assembly line in a car factory might be a more appropriate analogy since software development is a continuous cycle.

Before the manufacturer releases the car to the public, it must pass through numerous assembly stages, tests, and quality checks. Workers have to make the chassis, add the motor, wheels, doors, electronics, and a finishing paint job to make it appealing to customers.

DevOps pipelines work similarly.

Before releasing an app or a new feature to users, you first have to write the code. Then, make sure that it doesn't lead to any fatal errors that might cause the app to crash. Avoiding such a script involves running various tests to grope out any bugs, typos, or mistakes. Eventually, once everything is working as intended, you can release the code to users.

From this simplified explanation, you can conclude that a DevOps pipeline consists of the build, test, and deploy stages.

Components of a DevOps Pipeline

To insure the law moves from one stage to the coming seamlessly requires enforcing several DevOps strategies and practices. The most important among them are nonstop integration and nonstop delivery( CI/ CD>
.

Continuous Integration
nonstop integration( CI>
is a system of integrating small chunks of law from multiple developers into a shared code repository as often as possible. With a CI strategy, you can automatically test the code for errors without having to wait on other team members to contribute their code.

Continuous Delivery
Continuous delivery( CD>
is an extension of CI. It involves speeding up the release process by encouraging developers to release code to production in incremental chunks.

Continuous Deployment
Continuous delivery and continuous deployment are similar in many ways, but there are critical differences between the two.

Having a comprehensive continuous operations strategy helps maintain maximum availability of apps and environments.
