Building a cache-based architecture

Caching involves temporarily storing data or files in an intermediate location positioned between the requester and the permanent storage. This practice is aimed at speeding up future requests and minimizing network bandwidth usage. Caching increases application speed and lowers cost. It allows you to reuse previously retrieved data. To increase application performance, caching can be applied at various layers of the architecture, such as the web layer, application layer, data layer, and network layer.

Typically, the server’s random-access memory (RAM) and in-memory cache engines are utilized to support application caching. However, if caching is coupled to a local server, then the cache will not persist data in case of a server crash. Most applications are in a distributed environment, so it’s better to have a dedicated caching layer that should be independent of the application life cycle. If you apply horizontal scaling to your...
