Zookeeper was designed to be a robust service, it exposes a simple API, inspired by the filesystem API, that allows to implement common coordination tasks, such as electing a master server, consensus, managing group membership and managing metadata. This work makes a basic implementation and evaluation of Zookeeper and simulation with some of the services offered to evaluate them and discover how distributed applications can benefit. Obtaining as a result that Zookeeper offers a stable, simple and high performance coordination service that provides the necessary tools to manage distributed applications without worrying about the loss of information.
