Developers often need to support their applications with low-latency reads and write to a high-performance database. In the past, those using AWS may have adopted Amazon ElastiCache for Redis, a fully-managed in-memory caching service. However, this solution required developers to write custom code to sync the cache with the database. Now, AWS has released MemoryDB for Redis, a Redis-compatible durable in-memory service. Although MemoryDB gives access to Redis data structures and API, it does not require a low-latency cache to enable low-latency, high-throughput data access.
