This leader-follower cluster is a thread-based representation of a classic server cluster, with a gateway to handle requests from clients, a leader to assign tasks to followers, and followers which perform tasks. The purpose of a leader-follower cluster is to have a horizontally scaled system that can handle high workloads and numerous tasks and requests, by distrbuting the work across many machines. This project represents an essential part of any large-scale system with many clients and tasks, and the goal was to get used to understanding and implementing the components of a distributed system, and the algorithms and techniques to solve common problems that come up when dealing with distributed systems.
