Fixing Sticky Session Management Issues: Consistent Hashing and Layered Reverse Proxy Approach
My team and I usually develop web-apps through a commonly-used partitioned strategy with an isolated REST API backend application-server that handles HTTP requests from a front-end web-server, usually served through Nginx. My web-app uses browser-cookie based user-authentication, handled by the application-server. The cookie value is mapped to an object that holds all information about the user. This information is calculated the first time the user logs in, and subsequent re

Consistent Hashing
In recent years, distributed systems have become popular due to concepts like cloud computing and big data. Distributed caches, which power many high-traffic websites, use a type of distributed hashing that takes advantage of an algorithm called consistent hashing. Before defining consistent hashing, let's quickly review the concept of hashing. Simple hashing Simple hashing is a basic method of generating a hash value from a given input using a hash function. The hash functio
