About This Domain
Domain 3 — Design and Implement Build and Release Pipelines — accounts for 50-55% of the AZ-400 certification exam. This domain evaluates your understanding of implement ci pipelines with build validation and quality gates, implement multi-stage cd pipelines with approvals and environments, design container build strategies with docker and container registries, and related concepts. Design and implement CI/CD pipelines including build automation, testing integration, artifact management, deployment strategies, and infrastructure as code. To pass this section you need practical knowledge of how these services and patterns work together in real-world architectures.
What You'll Be Tested On
- Implement CI pipelines with build validation and quality gates
- Implement multi-stage CD pipelines with approvals and environments
- Design container build strategies with Docker and container registries
- Implement infrastructure as code with Bicep, ARM, and Terraform
- Design release strategies: blue-green, canary, ring-based deployments
- Implement feature flags and progressive exposure
- Manage artifacts with Azure Artifacts, npm, and NuGet feeds
