Cost Optimization — AWS Solutions Architect Associate Practice Questions
Cost optimization is one of the five pillars of the AWS Well-Architected Framework and a core focus of the Solutions Architect Associate exam. It covers selecting the right pricing models (On-Demand, Reserved, Savings Plans, Spot), rightsizing compute resources, and eliminating waste through monitoring and automation. Candidates are expected to recommend cost-effective architectures without sacrificing reliability or performance. Questions often test trade-offs between storage tiers, data transfer costs, and managed services versus self-managed alternatives.
