Kubernetes Endpoints: Kubernetes keeps track of the IP addresses of running?

Short answer: pods for each service and updates the Endpoints resource. When a pod is added or removed, the service discovery system automatically updates the list.

Real-world example (ShopNest)

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

2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
