Azure Microservices DevOps Pipeline

I have a micro-service–based application already running on Azure and need a full DevOps pipeline that carries each change from commit all the way to live monitoring. The work must cover three clear stages—Build & Test, Release & Deploy, and Monitor & Operate—so that every push is automatically built, validated, shipped, and observed inside the Azure ecosystem.

What I expect you to put in place:
• A YAML-driven CI flow in Azure DevOps (or GitHub Actions if it fits better) that restores dependencies, runs unit/integration tests, and packages each microservice as a Docker image, pushing the result to Azure Container Registry.
• A CD flow that promotes images through dev, staging, and production with manual approval gates, deploying either to AKS or Azure App Service for Containers—whichever aligns with best practices you outline.
• Automated roll-back rules, secrets stored in Azure Key Vault, and environment-specific configuration handled through variables or Helm/Kustomize templates.
• Continuous monitoring wired to Azure Monitor and Application Insights so I can see logs, metrics, and alerts for every microservice after deployment.

Acceptance is met when a sample pull request triggers the pipeline, tests pass, the image lands in ACR, the service appears in my target environment, and live metrics become visible in the Azure portal without manual intervention.
