Simplified Client Interaction:?

Short answer: Clients interact with a single API Gateway instead of multiple microservices, reducing complexity on the client side.

Example code

Clients don’t need to know the exact endpoint for each service; they only interact with the API Gateway.

Real-world example (ShopNest)

ShopNest splits Catalog, Cart, Order, and Payment into services so teams can deploy catalog changes without redeploying payments.

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.
