What is Azure DevOps?

Azure DevOps is an enterprise-grade SaaS and on-premises suite provided by Microsoft that provides end-to-end DevOps toolchains for developing, testing, building, and deploying applications.

Key Definition: Azure DevOps combines Agile planning tools (Boards), code hosting (Repos), enterprise CI/CD pipelines (Pipelines), package hosting (Artifacts), and automated testing (Test Plans).

Core Services of Azure DevOps

Service Function
Azure Boards Agile project management, Kanban boards, backlogs, and task tracking.
Azure Repos Git repository hosting and Team Foundation Version Control (TFVC).
Azure Pipelines Language, platform, and cloud-agnostic CI/CD engine.
Azure Artifacts Hosted package management (npm, NuGet, Maven, Python, Universal Packages).
Azure Test Plans Manual and exploratory testing framework.

Key Concepts & Terminology

  • Organization: The top-level boundary in Azure DevOps hosting projects.
  • Project: A isolated container inside an organization holding boards, repos, pipelines, and artifacts.
  • Pipeline: The workflow configuration that defines how code is built, tested, and deployed.
  • Stage: A logical collection of related jobs (e.g., Build, Test, Deploy_Staging, Deploy_Prod).
  • Job: A series of steps run by an agent node.
  • Agent Pool: A cluster of build/deployment agents (Microsoft-hosted or Self-hosted).
  • Service Connection: Secure credential configuration enabling Pipelines to connect to external clouds (Azure, AWS, Kubernetes).
