Building a Fault-Tolerant Key-Value Store

It’s a Key-Value Store written in C++, which supports the four CRUD operations with additional support for load balancing and fault tolerance. It uses a ring-based DHT, and keeps three replicas of each key-value pair with a quorum-based consistency model. Beneath the KV store, there is a distributed membership protocol which keeps track of the ring in the event of a new node joining or when a node fails. It was the programming project of the University of Illinois’s online Cloud Computing Concepts course, which I got the complete grade.
