A civic operations team needs an in-memory cache on EC2 with a very large RAM footprint. Which instance family awareness best applies?
Select an answer to reveal the explanation.
Short Explanation
Big in-memory civic cache means reach for memory-optimized instances—the family built around lots of RAM. Compute-optimized and storage-optimized optimize different dials, and families are definitely not all the same mix of resources.
Full Explanation
EC2 instance families are differentiated by resource balance: memory-optimized types emphasize large RAM for in-memory caches and similar workloads. Compute-optimized and storage-optimized families prioritize CPU and disk characteristics instead. Recognizing that families map to workload traits—not identical ratios—is essential Cloud Practitioner knowledge. Civic in-memory caching is a clear memory-optimized scenario contrasted with CPU- or disk-bound jobs.
