Introduction

Azure App Service is the fastest path to production ShopNest SaaS — managed PaaS with scaling, slots, and SSL without managing IIS yourself.

After this article you will

  • Choose App Service plan (F1/B1/P1 cost in INR)
  • Deploy via VS publish and GitHub Actions
  • Configure connection strings in Portal
  • Use deployment slots and Managed Identity
  • Enable logging and custom domain

Prerequisites

Concept deep-dive

PlanApprox INR/moUse
F1 Free₹0Dev/demo only
B1 Basic~₹1,000+Small ShopNest staging
P1v3 Premium~₹8,000+Production SLA, slots

Managed Identity: App Service authenticates to Azure SQL without password in connection string — Authentication=Active Directory Managed Identity.

Deployment slots: Deploy to staging, smoke test, swap to production — zero-downtime.

Hands-on — ShopNest Production SaaS Web App

  1. Create App Service + publish ShopNest.Web.
  2. Application settings: ConnectionStrings, Jwt__Key (never in code).
  3. Enable staging slot; swap after validation.
  4. Custom domain + free managed certificate.
  5. Stream logs: az webapp log tail.

Common errors & best practices

  • Connection string in appsettings.Production committed — use Portal settings.
  • F1 cold start and no custom domain SSL on free tier limits.
  • Always On disabled on Basic — app sleeps.

Interview questions

Q: App Service vs VM?
A: PaaS — Microsoft patches OS; you deploy DLL/container only.

Q: Slot swap?
A: Instant traffic switch staging↔production after warm-up.

Summary

  • App Service PaaS for ShopNest SaaS production
  • Secrets in Portal not source control
  • Managed Identity removes SQL passwords
  • Slots enable safe releases

Previous: Docker
Next: CI/CD with GitHub Actions

FAQ

Linux vs Windows App Service?

Linux + container often cheaper; Windows for legacy IIS needs.

Scale out?

Manual instance count or auto-scale on CPU/requests.
