Zookeeper

Zookeeper is an open-source software tool that helps manage and coordinate distributed systems, ensuring that various components of an application work together smoothly. It acts like a reliable central hub that keeps track of the status and configuration of services, helps with synchronization, and manages shared data. This is particularly useful for large applications running on multiple servers, where it's essential to have a consistent and organized way to communicate and manage information. Essentially, Zookeeper enhances the reliability and ease of managing complex computing environments.
