How do you implement stage-based deployment?

Short answer: Define stages in YAML for Dev, QA, Staging, and Production. Example: stages: stage: Build jobs: job: BuildJob steps: script: dotnet build stage: Deploy dependsOn: Build jobs: deployment: DeployJob environment: 'Production' strategy: runOnce: deploy: steps: script: echo Deploying to Production

Real-world example (ShopNest)

ShopNest on Azure typically uses App Service + SQL Database + Blob Storage + Application Insights for monitoring.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
