The master server consists of several components including a Kube-API server, an ETCD storage, a Kube-controller-manager, a cloud-controller-manager, a Kube-scheduler, and a DNS server for Kubernetes services. It’s likely to have a multi-master setting for great accessibility, but by default, there is an individual master server which functions as a supervising node and point of connection.

Kubernetes observes a client-server architecture. It is compact in nature which indicates that it can work on several public or private cloud platforms such as AWS, Azure, OpenStack, or Apache Mesos. The principal purpose of Kubernetes is to mask the complexity of maintaining a fleet of containers by implementing REST APIs for the functionalities needed. Kubernetes produces very flexible infrastructure with zero downtime deployment capacities, automated rollback, scaling, and self-healing of containers. Kubernetes is a robust open source orchestration tool developed by Google for operating microservices or containerized applications beyond a distributed cluster of nodes.
