Zookeeper - Introduction

Introduction

Zookeeper is one of the famous apache's projects which is used to provide synchronized services across the servers i.e. it's a centralized infrastructure. It is very hard to manage and coordinate the different cluster at a time but zookeeper with its advanced API with the simple Architecture solves this issues. With the help of zookeeper, we can focus more on development rather than managing the clusters. 

Zookeeper does this by creating a file in its server known as znode, which resides in the memory of zookeeper. This node can be updated by any nodes in the clusters to update their status. This updated status can be gained by other nodes so that they can change their behaviors to provide the perfect services.
