What are common performance bottlenecks in Azure-hosted .NET apps?

Short answer: Database latency or unoptimized queries. Blocking synchronous calls instead of async patterns. Memory or CPU constraints on App Service Plan. Excessive cold starts in serverless functions. Poor caching strategy or missing CDNs.

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.
