CloudWatch

Developers often start Lambda projects without frameworks, forcing manual setup of API Gateway and CloudWatch integrations. As architectures grow, the 50MB default deployment size limit becomes a constraint, requiring webpack bundling per function to stay under limits and improve deployment speed.

DynamoDB provides limited built-in visibility into table usage, access patterns, and cost drivers. Developers must integrate external monitoring tools like CloudWatch, Prometheus, or DataDog to understand performance issues. Issues like hot partitions and throttling aren't automatically resolved, requiring developer expertise to diagnose.
