In this application, you learned how to make a Config server, also called as a gossip server that can store properties and pass information around to its peer nodes. In this chapter, we have made provisions for the client node to store and access information and have a life cycle. Also, we provided a master node, which can have control over any of the client nodes.
In the subsequent chapters, we will take this further and add capabilities for the server to scale and have fault tolerance.
