Amazon ElastiCache vs Azure Redis Cache: What are the differences?

Developers describe Amazon ElastiCache as "Deploy, operate, and scale an in-memory cache in the cloud". ElastiCache improves the performance of web applications by allowing you to retrieve information from fast, managed, in-memory caches, instead of relying entirely on slower disk-based databases. ElastiCache supports Memcached and Redis. On the other hand, Azure Redis Cache is detailed as "A fully managed, open source–compatible in-memory data store". It perfectly complements Azure database services such as Cosmos DB. It provides a cost-effective solution to scale read and write throughput of your data tier. Store and share database query results, session states, static contents, and more using a common cache-aside pattern.

Amazon ElastiCache belongs to "Managed Memcache" category of the tech stack, while Azure Redis Cache can be primarily classified under "In-Memory Databases".
