In the dynamic world of technology, questions arise and solutions are sought. Stack Overflow stands as a beacon, guiding individuals through their technical difficulties with insights from experts around the globe.

In this blog, we dive into the world of Varnish, a pivotal tool for caching, web & API acceleration and content delivery, through the lens of the most asked and intriguing questions on Stack Overflow.

A microservice is an autonomous subset of a software system, often responsible for managing some of the data within that system. Together the microservices of a system form a microservice architecture: a dynamic array of semi-independent and loosely coupled computing processes.
