• [Zookeeper ](https://zookeeper.apache.org)- A dependency of Kafka. ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. In a clustered multi-server environment Zookeeper would be used to keep everything in sync
