Azure DevOps Build Pipeline

• A trigger tells a Pipeline to run
• A pipeline is made of one or more stages. A pipeline can deploy to one or more environments
• A stage is a way of organizing jobs in a pipeline and each stage can have one more jobs
• Each job runs on one agent. A job can also be agentless
• Each agent runs a job that contains one or more steps
• A step can be a task or script and is the smallest building block of a pipeline.
• As task is a pre-packged script that performs an action, such as invoking a REST API or publishing a build artifact.
• An artifact is a collection of files or packages published by a run.

Approvals, checks, and gates

Gate

Gates allow you to configure automated calls to external services, where the results are used to approve or reject a deployment.
