Redis — AWS Solutions Architect Associate Practice Questions
Redis is an open-source, in-memory data structure store that supports strings, hashes, lists, sets, sorted sets, and more, making it suitable for caching, session management, pub/sub messaging, and leaderboards. On the Solutions Architect Associate exam, Redis (via Amazon ElastiCache for Redis) is frequently the recommended choice when persistence, replication, Multi-AZ failover, or advanced data structures are required, as opposed to Memcached for simpler caching. Candidates should understand Redis cluster mode, read replicas, and the backup and restore capabilities that Memcached lacks. Exam questions often contrast Redis and Memcached to test whether candidates can select the right engine for a given requirement.
