How do you secure microservices using Azure services?

Short answer: Use Azure AD for authentication and authorization. Protect APIs with OAuth 2.0 / JWT tokens. Use API Management to enforce policies like rate limiting. Enable Private Endpoints / VNET integration for network isolation.

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.
