Corosync

Corosync is a software system that ensures multiple computers, or servers, work together smoothly as a cohesive group. It manages communication between servers, maintains synchronization, and ensures that critical data or tasks are shared consistently. If one server fails, Corosync helps the remaining servers recognize the failure and redistribute tasks to keep services running without interruption. This makes systems more reliable and resilient, especially in environments requiring high availability, such as data centers or cloud services.
