In this paper, we have created a chat application which uses socket programming for communication and all of the messages are saved in mongoDB. We have taken Docker application and hosted it on a three-node swarm cluster. This cluster uses Docker swarm technology to create a private network through which each of the nodes can talk to each other along a specified RPC port. The application runs in each node as a service and all load coming to the application has been balanced across three IP addresses in the swarm. This creates a distributed system and each node can act as a manager or a worker in the system. This technique helps to decrease the execution time to run servers on the cloud and can help improve the feasibility of online servers provided by the IT companies.
