Amazon ElastiCache vs Redis Cloud: 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 Cloud is detailed as "Enterprise-Class Redis for Developers". Redis Cloud is a fully-managed service for running your Redis dataset. It overcomes Redis’ scalability limitation by supporting all Redis commands at any dataset size. Your dataset is constantly replicated, so if a node fails, an auto-switchover mechanism guarantees data is served without interruption.
Amazon ElastiCache belongs to "Managed Memcache" category of the tech stack, while Redis Cloud can be primarily classified under "Redis Hosting".
Some of the features offered by Amazon ElastiCache are:
- Support for two engines: Memcached and Redis
- Ease of management via the AWS Management Console. With a few clicks you can configure and launch instances for the engine you wish to use.
- Compatibility with the specific engine protocol. This means most of the client libraries will work with the respective engines they were built for - no additional changes or tweaking required.
On the other hand, Redis Cloud provides the following key features:
- Infinite scalability, all commands supported
- Auto-failover with no ops
- Highest performance, even for small datasets
"Redis" is the top reason why over 53 developers like Amazon ElastiCache, while over 7 developers mention "Heroku Addon" as the leading cause for choosing Redis Cloud.
According to the StackShare community, Amazon ElastiCache has a broader approval, being mentioned in 342 company stacks & 79 developers stacks; compared to Redis Cloud, which is listed in 20 company stacks and 8 developer stacks.

We decided to use MemCachier as our Memcached provider because we were seeing some serious PostgreSQL performance issues with query-heavy pages on the site. We use MemCachier for all Rails caching and pretty aggressively too for the logged out experience (fully cached pages for the most part). We really need to move to Amazon ElastiCache as soon as possible so we can stop paying so much. The only reason we're not moving is because there are some restrictions on the network side due to our main app being hosted on Heroku.
I use a micro elesticache instance as a shared session store between the Node.js clusters of dojo.zerotoherojs.com and nightly.zerotoherojs.com
