SAA-C03 - Design Cost-Optimized Architectures - Section 4.4
Reduce compute cost through right-sizing, serverless adoption and AWS Compute Optimizer recommendations.
Use AWS Compute Optimizer recommendations, which analyse CloudWatch metrics to flag over-provisioned EC2 instances and suggest smaller types with equivalent performance at lower cost. Weigh migrating suitable workloads to AWS Lambda, billed only on invocation count and duration, against the overhead of always-on instances, and configure Auto Scaling to remove idle capacity during low-demand periods.
