Azure Pipelines is Microsoft’s CI/CD service within Azure DevOps. It automates build, test, and deployment workflows using YAML-defined pipelines and/or classic UI pipelines. It supports multi-platform builds (Linux/macOS/Windows) and can deploy to Azure and non-Azure targets (on-premises, AWS, GCP) via agents and integrations.
Microsoft positions Azure Pipelines as a CI/CD engine intended for enterprise use, with governance features and integration across the broader Azure DevOps suite (Repos, Boards, Artifacts, Test Plans) and Microsoft identity (Microsoft Entra ID). Official product documentation emphasizes support for a wide range of languages, platforms, and clouds.
