Azure DevOps Services: The Complete DevOps Platform Walkthrough
Azure DevOps Services is Microsoft's cloud-hosted DevOps platform that covers the full software delivery lifecycle. Unlike single-purpose tools, Azure DevOps ships five integrated services in one platform. Understanding what each service does — and how they work together — is essential for teams designing their engineering platform on Azure.
Azure Boards: Agile Work Tracking
Azure Boards is the project management layer. It supports Scrum, Kanban, and custom process templates. Work items — Epics, Features, User Stories, Tasks, Bugs — are organised in a hierarchical backlog and can be tracked on sprint boards, query-based views, and delivery plans that span multiple teams. Boards integrates directly with Azure Repos and Azure Pipelines, so commits and pull requests can be linked to work items for traceability.
Azure Repos: Git Source Control
Azure Repos provides cloud-hosted Git repositories with enterprise access controls. Branch policies are the key feature for platform teams: you can enforce pull request requirements, minimum reviewer counts, build validation that requires a successful CI build before merge, and linked work items. Azure Repos also supports TFVC for teams migrating from older Microsoft source control, though Git is the standard for new workloads.
Azure Pipelines: CI/CD
Azure Pipelines is the CI/CD engine. Pipelines are defined in YAML and support multi-stage workflows — build, test, stage, production — with environment approvals between stages. It integrates with Azure and non-Azure deployment targets: Azure Web Apps, AKS, VMs, AWS, and on-premises. The hosted agents support Linux, Windows, and macOS builds. For corporate environments, self-hosted agents can run within your virtual network.
Azure Artifacts: Package Management
Azure Artifacts is a hosted package feed that supports NuGet, npm, Maven, Python PyPI, and Universal Packages. Teams use it to publish internal libraries and share versioned packages across projects. Artifact feeds can act as upstream proxies to public registries like npmjs.com and NuGet.org, adding a governance layer over third-party dependency consumption.
Azure Test Plans: Quality Engineering
Azure Test Plans provides manual and exploratory testing capabilities integrated with the rest of the platform. Test cases are linked to work items and builds. Testers can capture results, screenshots, and recordings, and defects raised during testing are automatically linked to the tested build and story. For teams doing compliance testing or user acceptance testing, Test Plans provides the audit trail that automated tests cannot.
Key Takeaways
- Azure DevOps Services covers the full ALM lifecycle: plan, code, build, test, deploy
- The five services are independently usable but deliver maximum value when integrated together
- Branch policies in Azure Repos and environment approvals in Azure Pipelines are the key governance controls for regulated teams
- Azure DevOps can deploy to any target — Azure, AWS, on-premises — making it suitable for hybrid and multi-cloud delivery pipelines
