Azure DevOps is Microsoft's comprehensive DevOps platform that provides integrated services for planning, developing, delivering, and operating software at scale. It encompasses five core services—Azure Boards, Repos, Pipelines, Test Plans, and Artifacts—that can be used together or independently to support the entire application lifecycle. Whether you're managing agile projects, automating CI/CD workflows, or hosting private packages, Azure DevOps centralizes collaboration across development teams. A critical insight: while many teams start with Pipelines for automation, the platform's real power emerges when you integrate work item tracking with source control and automated deployments, creating full traceability from idea to production.
