Module 4 — Configure Azure App Service

Grounded in MS Learn: az-104-manage-compute-resources → Configure Azure App Service (learn.wwl.configure-azure-app-services)

Overview

Fourth module of the AZ-104 compute path. Provision and operate Azure App Service web apps hosted on an App Service plan: create an app, use deployment slots for safe releases, secure the app, configure custom domains, back up/restore, and enable Application Insights monitoring.

Learning objectives (authoritative)

  1. Identify features and usage cases for Azure App Service.
  2. Create an app with Azure App Service.
  3. Configure deployment settings, specifically deployment slots.
  4. Secure your Azure App Service app.
  5. Configure custom domain names.
  6. Back up and restore your Azure App Service app.
  7. Configure Azure Application Insights.

Concepts introduced

  • Azure App Service — PaaS web/API/mobile backend hosting.
  • App Service plans — the plan/instance the app runs under.
  • Deployment slots — warm staging environments + zero-downtime swap.
  • App Service authentication (Entra/social), managed TLS/SSL, IP restrictions, managed identities.
  • Custom domains + TLS/Binding; backup & restore; Azure Application Insights telemetry.

Key terms & commands

  • Create app: az webapp create --resource-group <rg> --plan <plan> --name <app> --runtime "NODE|18-lts"
  • Deploy: az webapp deploy --src-path <zip> --type zip; slots: az webapp deployment slot create --slot staging, az webapp deployment slot swap --slot staging
  • Custom domain: az webapp config hostname add --hostname app.example.com + validate (CNAME/alias) + TLS bind cert.
  • Backup: az webapp config backup create; Monitoring: az monitor app-insights component + enable on app.

Hands-on

  • Create an app, deploy via ZIP, open a staging slot, deploy there, swap to production (observe zero downtime), and swap back to roll back.
  • Add a slot (sticky) app setting so a production key does not move to staging during swap.
  • Attach a custom domain with a cert and enable Application Insights to see requests/errors.

Exam focus

  • Deployment slots workflow (deploy → validate → swap → rollback) and the slot-settings vs app-settings difference (sticky settings stay with their slot).
  • App Service authentication = built-in identities module; custom domains need validation + TLS binding.
  • Autoscale/scale actually lives on the plan (see module 3), not the app.
  • Backup/restore of the app content + settings; Application Insights for runtime telemetry (not just VM diagnostics).
