Volume of Logs and Metrics:?

Short answer: With multiple microservices generating logs and metrics, it becomes difficult to manage, search, and analyze the data. Mitigation: Implement centralized logging and log aggregation to consolidate logs from all services.

Real-world example (ShopNest)

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