A city portal team wants a memory-based cache or in-memory database family to speed repeated reads and short-lived session data. Which AWS service family should they identify?
Select an answer to reveal the explanation.
Short Explanation
Memory-based services keep hot data on the tip of the tongue—fast reads for caches and short-lived sessions. ElastiCache and MemoryDB are the AWS names to remember for that. Backup protects copies, Glacier is archival object storage, and Textract reads documents—not an in-memory cache family.
Full Explanation
Amazon ElastiCache and Amazon MemoryDB represent AWS memory-based caching and in-memory database options used to accelerate frequent reads and similar low-latency patterns. AWS Backup orchestrates backups, Amazon S3 Glacier Instant Retrieval is an archival object storage class, and Amazon Textract extracts text from documents—none are the memory-based database/cache family.
