AWS Elastic Kubernetes Service (EKS) is a managed Kubernetes service offered by Amazon Web Services (AWS) that simplifies the process of deploying, managing, and scaling containerized applications using Kubernetes. With EKS, cloud architects can launch a fully managed and scalable Kubernetes control plane without worrying about the underlying infrastructure and updates.
Benefits of EKS for Cloud Architects
Easy Deployment and Management: EKS streamlines the deployment and management of containerized applications, as AWS takes care of the infrastructure and Kubernetes control plane.
High Availability: EKS is designed to provide high availability and scalability, ensuring that applications are always accessible and performant.
Strong Security: EKS prioritizes security, with features such as secure node communication, encrypted etcd data store, and integration with AWS security services.
Cost-Effective: EKS charges only for the resources consumed, making it a cost-efficient option for deploying and managing containerized applications.
Key Features of EKS
Managed Kubernetes Control Plane: EKS provides a managed control plane, eliminating the need for cloud architects to set up and maintain the infrastructure and Kubernetes components.
High Availability: EKS is built to provide high availability and scalability, ensuring that applications remain accessible and performant.
Robust Security: EKS offers a range of security features, such as secure node communication, encrypted etcd data store, and integration with AWS security services.
Integration with AWS Services: EKS integrates with a wide range of AWS services, including Amazon S3, Amazon RDS, Amazon DynamoDB, and more, making it easy to build and scale applications using preferred AWS services.
Deploying Applications on EKS
To deploy applications on EKS, cloud architects must first set up an AWS account and create an EKS cluster using the AWS Management Console, AWS CLI, or AWS CloudFormation template.
Next, cloud architects must configure the nodes by launching EC2 instances and installing necessary software, including the Kubernetes CLI (kubectl), AWS CLI, and Amazon EKS-optimized Amazon Linux 2 AMI.
Once the nodes are configured, applications can be deployed using tools such as Helm, Kustomize, or Terraform. Deployment requires creating a Kubernetes manifest that specifies the desired state of the application.
Managing Applications on EKS
Updating applications on EKS is a straightforward process, using the Kubernetes CLI (kubectl) to update manifests and apply changes. Scaling applications is also easily done by increasing or decreasing resources as needed.
