What is Managed Identity and why is it important?

Short answer: Strong Answer: Managed Identity eliminates the need to store credentials. Problem without it: Secrets stored in config Risk of leakage Solution: Azure assigns identity to service

Example code

App Service → accesses Key Vault securely Real-world Example: Instead of: var secret = "hardcoded-key"; We use: Managed Identity + Key Vault Why interviewers ask: To check security maturity level

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.
