Communication Overhead:?

Short answer: Microservices often communicate over the network, leading to latency and performance overhead. Mitigation: Use gRPC or Kafka for faster communication, minimize inter-service calls, and introduce caching.

Real-world example (ShopNest)

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