While Docker provides the lifecycle management of containers, Kubernetes takes it to the next level by providing orchestration and managing clusters of containers. As you know, your application created using the microservice architecture will contain a couple of separated, independent services. How do we orchestrate and manage them? Kubernetes is an open-source tool that's perfect for this scenario. It defines a set of building blocks which provide mechanisms for deploying, maintaining, and scaling applications. The basic scheduling unit in Kubernetes is called a pod. Containers in a pod run on the same host, share the same IP address, and find each other via localhost. They can also communicate with each other using standard inter-process communications, such as shared memory or semaphores. A pod adds another level of abstraction to containerized components...
