Kubernetes Features

In this tutorial, we will discuss about Kubernetes Features. Following are the essential features of Kubernetes.

Kubernetes Features
1. Pod

A pod is a deployment unit in Kubernetes with a single Internet protocol address. A pod is a collection of containers with shared storage and network and a specification for running them. Each pod is allocated its own IP address. Containers within a pod share this IP address, port space and can find each other via localhost.

2. Horizontal Scaling

It is an important feature in the Kubernetes. The Horizontal Pod Autoscaler automatically scales the number of Pods in a replication controller, deployment, replica set, or stateful set based on observed CPU utilization (or, with custom metrics support, on some other application-provided metrics)

3. Automatic Bin Packing

Kubernetes places containers automatically based on the required resources and other restrictions without impairing availability.

4. Service Discovery and load balancing

Kubernetes assigns the IP addresses and a Name of DNS for a set of containers and balances the load across them.

5. Automated rollouts and rollbacks

Kubernetes rolls out changes to the application or its configuration while monitoring application health to ensure it doesn’t kill all your instances simultaneously. If something goes wrong with Kubernetes, you can roll back the change.

6. Persistent Storage

Kubernetes provides an essential feature called “persistent storage” for storing the data, which cannot lose after the pod is killed or rescheduled. Kubernetes supports various storage systems for storing the data, such as Google Compute Engine’s Persistent Disks (GCE PD) or Amazon Elastic Block Storage (EBS). It also provides the distributed file systems: NFS or GFS.

7. Self-Healing

This feature plays an essential role in the concept of Kubernetes. Kubernetes allows to replaces and reschedules containers when nodes die. It also kills containers that don’t respond to user-defined health checks and doesn’t advertise them to clients until they are ready to serve.

8. Run everywhere

Kubernetes is an open-source tool and gives you the freedom to take advantage of on-premises, hybrid, or public cloud infrastructure, letting you move workloads to anywhere you want
