MLVN stands for MongoDB, Linux, Varnish and Node.js - a combination that brings together storage, operating system, caching and server runtime in a cohesive stack.

The strength of the stack is its balance of performance and flexibility: MongoDB handles fast, scalable document storage, Linux provides a stable foundation, Varnish supplies lightning-fast caching close to the user, and Node.js manages asynchronous operations with ease.

MLVN is ideal for modern web services where responsiveness and scalability are essential. It works particularly well when you need real-time updates, efficient caching strategies, and a flexible database that can handle large volumes.
