R-Type Instances — AWS Solutions Architect Associate Practice Questions

R-type EC2 instances (R4, R5, R6g, R7g, and variants) are the primary memory-optimized family on AWS, offering high RAM-to-vCPU ratios for workloads that benefit from keeping large datasets in memory. The exam associates R-type instances with use cases such as SAP HANA, large relational databases configured for in-memory caching, and high-performance analytics engines. The 'g' suffix variants use AWS Graviton ARM-based processors and offer improved price-performance, which matters in cost-optimization questions. Knowing that R-type instances sit above general-purpose M-type instances in memory capacity but are distinct from the ultra-high-memory X and U families helps you answer tiered sizing questions accurately.
