Rightsizing, Purchasing, and Elastic Workloads

Where this lesson fits

This lesson covers Domain 4: Design Cost-Optimized Architectures, Task 4.2: Design cost-optimized compute solutions. Domain 4 represents 20% of the scored content of SAA-C03. Compute is usually the largest line on an AWS bill, so exam stems in this task give you a workload profile (steady, spiky, interruptible, short-lived, unknown) and ask for the cheapest design that still meets availability and performance requirements.
