Azure DevOps provides five integrated services: Azure Repos for Git source control, Azure Pipelines for CI/CD (YAML-based, multi-platform, cloud-hosted agents), Azure Boards for agile project management (Scrum, Kanban), Azure Artifacts for package management (npm, NuGet, Maven), and Azure Test Plans for manual and exploratory testing.
Enterprise Azure DevOps requires: organization/project hierarchy design, pipeline templates (reusable YAML for consistent builds), service connections (Azure, Kubernetes, Docker registries), branch policies (PR reviews, build validation, status checks), and security (project-level permissions, pipeline approvals, variable groups).
