Elasticache - Usecase

Hi, If someone wants data, you can deliver that data much faster if it's cached. Consider caching your data if the following is true: a) Your data is slow or expensive to get when compared to cache retrieval. b) Users access your data often. c) Your data stays relatively the same, or if it changes quickly staleness is not a large issue.

Usecases for Redis/Memcache are product catalogs in e-comm portal, Selling tickets of an event. Basically, users tend to opt out of slower sites and hence caching improves data delivery much faster.
