EKS (Kubernetes on AWS)
For companies looking to orchestrate containers efficiently and at a large scale, Amazon EKS is the ideal solution. It manages the complexity of Kubernetes, allowing you to focus on the deployment and management of your containerized applications, with the security and reliability of the AWS infrastructure.
What is Amazon EKS?
EKS is a fully managed service that simplifies running Kubernetes on AWS. Kubernetes is an open-source orchestration platform that automates the deployment, scaling, and management of containerized applications. With EKS, AWS takes care of managing the Kubernetes Control Plane, which is the most complex part of the architecture, ensuring its high availability and resilience.
With EKS, your IT team has the flexibility to:
- Focus on the Core Business: Eliminates the need to manage and update the Control Plane, freeing the team to focus on application development and logic.
- Scalability and Resilience: Ensures the Kubernetes cluster is highly available and scalable, distributed across multiple Availability Zones.
- Native Integration with AWS: Integrates seamlessly with other AWS services, such as IAM for authentication and authorization, VPC for networking, and ELB for load balancing.
How EKS works in practice
In an EKS architecture, you have the Control Plane managed by AWS and the Worker Nodes (EC2 instances or AWS Fargate) where your containerized applications are executed. EKS ensures secure communication between these two parts.
- Node management: You can use managed node groups to provision and manage EC2 instances, or opt for AWS Fargate for a "serverless" model, where you don't have to worry about the underlying virtual machines.
- Automated deployments: Facilitates the implementation of strategies like Blue/Green or Canary Deployments for updates with no downtime.
- Cost reduction: Allows the use of Spot instances for flexible workloads, optimizing computing costs.

Benefits of this architecture
Amazon EKS offers the power of Kubernetes with the reliability and simplicity of a managed service, making it the primary choice for container-based architectures in the AWS cloud.
- Portability: Your applications run in containers, which can be easily moved between cloud or on-premise environments.
- Unlimited scalability: EKS and managed node groups handle horizontal scaling automatically, handling any volume of traffic.
- Robust security: Native integration with AWS security tools, such as IAM, and Kubernetes network policies.
- Automation and DevOps: Promotes end-to-end automation, from CI/CD to monitoring, accelerating the development cycle.
