▪ (1) When a client needs to access data, it first checks to see if the

data is in the cache.

▪ (2) If the data is in the cache, the client retrieves it from the cache and

returns it to the caller.

▪ (3) If the data is not in the cache, the client retrieves it from the

database, stores it in the cache, and then returns it to the caller.

▪ Some of caching systems provide read-through and writethrough/write-behind operations. In these systems, client

application retrieves data over by the cache.

▪ For not supported Caches, it's the responsibility the applications

use the cache and update the cache if there is a cache-miss.

▪ Microservices good example to implement Cache-Aside pattern, it

is common to use a distributed cache that is shared across

multiple services
