Amazon Elastic Kubernetes Service (Amazon EKS) is a fully managed Kubernetes service that makes it easier to deploy, manage, and scale containerized applications using Kubernetes.
Amazon EKS eliminates the need to install, operate, and maintain your own Kubernetes control plane. It provides a managed environment for deploying, managing, and scaling containerized applications using Kubernetes.
Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications.
Key features of Amazon EKS include automatic upgrades, integration with AWS services, high availability with multiple availability zones, security with IAM and VPC, and simplified Kubernetes operations.
A Kubernetes cluster is a collection of nodes (Amazon EC2 instances) that run containerized applications managed by Kubernetes. It includes a control plane and worker nodes.
To create an EKS cluster, you use the AWS Management Console, AWS CLI, or AWS CloudFormation. EKS automatically provisions the control plane and worker nodes.
Kubernetes nodes are the worker machines that run containers. They host pods, which are the smallest deployable units in Kubernetes.
Amazon EKS automatically handles the upgrades of the Kubernetes control plane. It schedules and applies updates while ensuring minimal disruption to the applications running on the cluster.
Amazon EKS provides managed Kubernetes clusters, while Amazon ECS provides managed Docker container orchestration. EKS is better suited for complex microservices architectures using Kubernetes.
You can scale applications in EKS by adjusting the desired replica count of Kubernetes Deployments or StatefulSets. EKS automatically manages the scaling of underlying resources.
Amazon EKS Managed Node Groups simplify the deployment and management of worker nodes in an EKS cluster. They automatically provision, configure, and scale nodes.
Amazon EKS uses Amazon VPC for networking. It creates a VPC and subnets for your cluster, and each pod in the cluster gets an IP address from the subnet.
A Kubernetes Pod is the smallest deployable unit in Kubernetes. It represents a single instance of a running process in the cluster and can consist of one or more containers.
Amazon EKS integrates with various AWS services like IAM for access control, Amazon VPC for networking, and CloudWatch for monitoring and logging.
Yes, you can run multiple Kubernetes clusters on Amazon EKS, each with its own set of worker nodes and applications.
A Kubernetes Deployment is suitable for stateless applications, while a StatefulSet is designed for stateful applications that require stable network identifiers and ordered, graceful scaling.
You can secure an EKS cluster by using AWS Identity and Access Management (IAM) roles, integrating with Amazon VPC for networking isolation, and applying security best practices to your Kubernetes workloads.
A Kubernetes Operator is a method of packaging, deploying, and managing an application using Kubernetes-native APIs. It allows for more automated management of complex applications.
You can use Kubernetes Deployments or other tools like Helm to automate application deployments in Amazon EKS. These tools help manage the lifecycle of containerized applications.
Amazon EKS supports high availability by distributing control plane components across multiple availability zones. It also offers features like managed node groups and Auto Scaling for worker nodes.
