Amazon ElastiCache vs Redis: 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, Redis is detailed as "An in-memory database that persists on disk". Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
Amazon ElastiCache belongs to "Managed Memcache" category of the tech stack, while Redis can be primarily classified under "In-Memory Databases".
"Redis" is the top reason why over 53 developers like Amazon ElastiCache, while over 842 developers mention "Performance" as the leading cause for choosing Redis.
Redis is an open source tool with 37.4K GitHub stars and 14.4K GitHub forks. Here's a link to Redis's open source repository on GitHub.
Airbnb, Uber Technologies, and Instagram are some of the popular companies that use Redis, whereas Amazon ElastiCache is used by Airbnb, Instacart, and Asana. Redis has a broader approval, being mentioned in 3264 company stacks & 1786 developers stacks; compared to Amazon ElastiCache, which is listed in 349 company stacks and 79 developer stacks.
