KUBERNETES OVERVIEW

Kubernetes (also known as K8s) is a lightweight, extensible, open-source architecture for managing containerized workloads and utilities, which enables both declarative setup and automation. It has a big, fast-growing ecosystem. Kubernet's programs, assistance and software are readily accessible. There are three reason, why Kubernetes is so useful by going back in time, which are Traditional deployment era, Virtualized deployment era, and Container deployment era.

Kubernetes VS Docker

The basic distinction between Kubernetes and Docker is that Kubernetes is intended to run through a cluster when Docker is operating on a single node. Kubernetes is more comprehensive than Docker Swarm and is structured to organize clusters of nodes on a scale of development in an effective manner. Kubernetes pods—scheduling units that can include one or more containers in the Kubernetes ecosystem—are spread between nodes to provide high availability.

Kubernetes Advantages

See the table below, Picture Explanations

Traditional deployment era	Organizations ran applications on physical servers. There was no way to define resource boundaries for applications in a physical server, and this caused resource allocation issues.
Virtualized deployment era	Virtualization allows applications to be isolated between VMs and provides a level of security as the information of one application cannot be freely accessed by another application.
Container deployment era	Containers are similar to VMs, but they have relaxed isolation properties to share the Operating System (OS) among the applications. Therefore, containers are considered lightweigh.
