Azure Pipelines: A Complete Guide to CI/CD Automation

Azure Pipelines is a cloud-based CI/CD service that automates building, testing, and deploying code to any platform or cloud, and is part of the broader Azure DevOps suite.

Core Concepts

• Continuous Integration (CI) — automatically builds and tests code with every commit
• Continuous Delivery (CD) — automatically deploys validated builds to target environments
• Pipelines — defined using YAML files or the classic visual designer
• Agents and Agent Pools — the compute that runs pipeline jobs, either Microsoft-hosted or self-hosted

Building a Pipeline

• Connect your repository (Azure Repos, GitHub, Bitbucket, and others)
• Define build steps such as restore, compile, and test
• Add release stages with approvals and environment-specific variables
• Configure triggers so pipelines run automatically on code changes

Key Benefits

• Supports virtually any language, platform, and cloud target
• Parallel jobs speed up build and test cycles
• Built-in approval gates and release policies for governance
• Rich marketplace of extensions for testing, security scanning, and notifications
