Caching

In today’s high-performance computing landscape, caching is no longer optional—it’s essential. Whether you’re scaling a simple web app or building a complex microservices architecture, caching is one of the most effective ways to improve response times, reduce backend load, and deliver a better user experience.
However, not all caches are created equal. There’s an important distinction between internal (in-process) and external (out ofprocess) caches. Understanding this difference, along with the various types of caches like in-memory, distributed, and database backed caches, is key to designing efficient, scalable systems.
