How does Caching on the Backend work? (System Design Fundamentals)

Описание: Caching strategies, Distributed Caching, caching with Redis and Node.js, Eviction Policies, Write-Through Cache and Least Recently Used (LRU) cache are all important terms when it comes to designing an efficient system with a caching layer, be it on AWS, Azure, or any other cloud provider. In this video lesson, you're gonna learn everything you need about caching in an easily explained way, discuss the pros and cons, and see an example implementation of it.
