Consistent Hashing Explained: Hash Rings, Virtual Nodes, and Load Balancing

The article details the consistent hashing algorithm, describing how a hash ring and virtual nodes distribute keys across servers, minimize data movement during node changes, compare it with simple modulo hashing, and outline typical use cases such as load balancing, distributed caches, storage systems, and database sharding.
