Can you explain the concept of "bounded contexts" in microservices?

Short answer: A bounded context defines the boundary within which a particular domain model is valid. In microservices, each service represents a bounded context, encapsulating business logic, data, and rules. This ensures that models are consistent and isolated within each service, preventing conflicts between different parts of the application.

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.
