Kubernetes, an open-sourced application that lets users create and manage containerized applications, allows you to use in AWS to manage entire clusters of EC2 instances. A Kubernetes cluster is a logical grouping of EC2 instances that house your containers. You may then use those instances to run Docker containers and create any kind of containerized application with them. You can establish systems for deployment, maintenance, and scaling, employing the same tools you would normally use on an onsite or cloud infrastructure.

Running Kubernetes in the AWS cloud is simple, highly scalable, and available using the certified and fully-managed Amazon Elastic Container Service for Kubernetes (EKS).

How It Works

Kubernetes manages clusters of AWS instances. Depending on the compute resources and resources necessary, Kubernetes can automatically schedule containers on a cluster. Clusters are grouped in pods for ease of running and scaling.

Through its control plane software, Kubernetes can choose the appropriate time and place to run your pods. It also handles traffic routing and scaling for pods depending on resources used, or other factors that you can set. Kubernetes can initiate pods on a cluster automatically depending on their own resource requirement. It can also restart pods in the event of instance failure. Pods are provided their own IP address and one DNS name for easy communication between services and your onsite architecture.

Benefits of Using Kubernetes

  • Continuous Improvement and Functionalities – As an open-sourced software, Kubernetes is maintained by a community of volunteers that continue to improve it. It is also open to various other open source projects, providing extensions, integrations, and plugins that can help improve and expand your software architecture.
  • Scaling – You may run and scale containerized applications over a cluster of servers.
  • Upload Applications – You may easily move containerized applications from onsite development environments to cloud production deployments using the identical operational tooling.
  • Run on the Cloud – Run your application from anywhere in the world, using highly available and scalable Kubernetes clusters. Containerized applications remain fully compatible with any Kubernetes deployments you have running onsite.

Running Kubernetes on AWS

AWS allows you to choose between personally managing the Kubernetes infrastructure or use AWS EKS to get an automatically provisioned managed control plane. Regardless, you get all the benefits of Kubernetes on the cloud.

To use Kubernetes, you can run it on your own through Amazon EC2 instances or use Amazon EKS.
