What is DevOps

What is DevOps?What is DevOps?

DevOpsDevOps is a culture, movement or practice, which aims at establishing a culture and environment where building, testing, and releasing software, can happen rapidly, frequently, and more reliably.

Why DevOps?

Continuous IntegrationContinuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.By integrating regularly, you can detect errors quickly, and locate them more easily.

Maintain a single source repositoryAutomate the buildMake your build self-testingEvery commit should build on an integration

machineKeep the build fastTest in a clone of the production environmentMake it easy for anyone to get the latest

executableEveryone can see what’s happeningAutomate deployment

Continuous Integration: the Practices

Developers check out code into their private workspaces. When done, commit the changes to the repository. The CI server monitors the repository and checks out changes when

they occur. The CI server builds the system and runs unit and integration tests. The CI server releases deployable artefacts for testing. The CI server assigns a build label to the version of the code it just

built. The CI server informs the team of the successful build. If the build or tests fail, the CI server alerts the team. The team fix the issue at the earliest opportunity. Continue to continually integrate and test throughout the project.
