AWS EKS

What is AWS EKS?

AWS Elastic Kubernetes Service (EKS) is a managed Kubernetes solution that lets you run containerized applications without manually handling clusters. It automates deployment, scaling, and maintenance, making Kubernetes easier to use on AWS.

What is Kubernetes?

Kubernetes is a free and open-source system.

It allows you to run and control containerized applications efficiently.

A vast developer community contributes to its growth.

AWS ensures that EKS stays aligned with the newest Kubernetes updates.

How AWS EKS Works?

1. Control Plane (Managed by AWS)

• Runs Kubernetes API servers and cluster state storage.
• Spans multiple zones for high availability.

2. Worker Nodes (Managed by You)

• Hosted on EC2 instances or Fargate (serverless).
• Connects to the control plane securely.

3. Networking & Security

• Uses Amazon VPC for private networking.
• Supports IAM roles, RBAC, and encryption.

Why Use AWS EKS?

• No Cluster Maintenance – AWS takes care of upgrades and security.
• Scalable – Automatically adjusts to demand.
• Hybrid Support – Works on AWS, on-prem, or hybrid setups.
• Secure – IAM, encryption, and VPC isolation built-in.
• Multi-Zone Resilience – Prevents downtime.

Final Thought

AWS EKS removes the headache of managing Kubernetes, letting you focus on building applications instead of maintaining infrastructure.
