Amazon Elastic Kubernetes Services (AWS EKS)
What is Amazon EKS?
Amazon Elastic Kubernetes Service (Amazon EKS) is a managed Kubernetes service that simplifies running Kubernetes on AWS and on-premises. It allows you to deploy, scale, and manage containers using open-source Kubernetes, a proven system. With Amazon EKS, you have a certified Kubernetes-conformant service compatible with upstream Kubernetes-based applications.
To efficiently manage your Kubernetes clusters, Amazon EKS utilizes EKS to handle the Kubernetes Control Plane Nodes autonomously. This includes scheduling containers, monitoring application availability, and storing cluster data. By integrating with various AWS networking and security services, such as ALBs for load distribution, AWS IAM with RBAC, and VPC support for pod networking, Amazon EKS allows you to leverage AWS infrastructure’s performance, scale, reliability, and availability.
You can seamlessly manage AWS services directly from your Kubernetes containers using AWS Controllers for Kubernetes (ACK). This enables you to build scalable and highly available Kubernetes applications. The integrated EKS console gives you a centralized location to manage, visualize, and troubleshoot your Kubernetes applications running on Amazon EKS.
Custom Kubernetes clusters on Amazon EC2 stand out for their infrastructure-agnostic capabilities. This flexibility allows businesses to seamlessly transition their operations between diverse environments, from cloud-based to on-premise solutions. This feature particularly benefits organizations that maintain system consistency across multiple deployment scenarios.
Handling your Kubernetes cluster control plane on EC2 can save substantial costs. Typically, outsourcing this management role to AWS incurs higher expenses. By overseeing the control plane internally, businesses can reduce their operational costs while leveraging the Kubernetes architecture’s robust capabilities.
Implementing a custom Kubernetes cluster on EC2 greatly benefits the local development lifecycle. Development teams can mirror the production environment locally, which minimizes discrepancies and configuration drift between local setups and the main cluster in the cloud. This synchronization ensures a smoother transition and deployment process from development to production, promoting more efficient and error-free releases.

In summary, while there are different options available for running containers on AWS, Amazon EKS stands out with its advanced capabilities and interfaces with AWS services and solutions from technology partners. By partnering with an AWS Advanced Consulting Partner, you can fully leverage the benefits of EKS and receive the necessary support to successfully manage and scale containerized applications using Kubernetes on AWS.
Discovery of the service
AWS Cloud Map is a resource discovery tool for the AWS cloud. Cloud Map allows you to provide dynamically changing application resources with unique names and addresses. When you use this technique, your online service will constantly locate the most recent places for the resources of your apps Using the open-source Kubernetes connector external-dns, internal service locations are propagated to the Cloud Map service registry as Kubernetes services are started and removed upon termination. Users can use the Cloud Map registry to discover Kubernetes services, which operate as a common service registration for all containerized workloads.
Mesh of Service
For large, distributed applications with a range of microservices that link to one another, Service Mesh is an excellent choice. AWS App Mesh lets you keep tabs on the progress of your app at every stage. You may add additional services to the mesh, determine traffic routing, and set up security features like encryption with the AWS App Mesh controller for Kubernetes. Pod registration on AWS Cloud Map for service discovery is also possible with App Mesh. In the App Mesh bootstrap configuration, metrics, logs, and traces are exported to the endpoints defined in Envoy. For establishing traffic pathways, circuit breaking, retries, and other controls across mesh-enabled microservices, App Mesh offers an API. Every request you make to a service will be encrypted using the App Mesh Mutual TLS. Additional authentication protections can be used to further limit communication to only those services that you approve of.
Native networking for VPCs
For your EKS clusters on an Amazon VPC, you have the option of creating your own VPC security groups and network access control lists (ACLs). Because no one else has access to your computing resources, you may utilize them to build programmes that are both secure and dependable. Container network interface of Amazon VPC is used by EKS to provide IP addresses to Kubernetes pods (CNI). Amazon EKS and Project Calico can let your Kubernetes workloads benefit from fine-grained networking management. Each service can have its own level of access control by utilising the Kubernetes network policy APIs.
IAM Authenticator for AWS
As part of Amazon EKS, Kubernetes RBAC (Role-Based Access Control) is linked with AWS IAM. Kubernetes control plane nodes can be tightly controlled using RBAC roles, which can be allocated to individual IAM objects.
IAM for Service Accounts
Amazon EKS can be made available to Kubernetes service accounts using IAM. This allows for precise control over access to additional containerized services, external AWS resources like databases and secrets, and even third-party services and apps running outside of AWS. By leveraging IAM user roles, administrators can finely tune permissions and restrictions at various levels, ensuring the security and integrity of the cluster.
In addition to access management, EKS prioritizes availability and automatic patching for a seamless Kubernetes deployment. To ensure high availability, EKS runs Kubernetes with three masters across three AWS availability zones. This distributed setup guarantees that even if one availability zone experiences an outage, the remaining zones will maintain the operational status of the Kubernetes cluster, minimizing downtime and ensuring business continuity.
Moreover, EKS goes beyond availability by implementing automatic patching capabilities. With this feature, EKS automatically applies patches and updates to the Kubernetes cluster, keeping it up to date with the latest security fixes and feature enhancements. This proactive approach to patching eliminates the need for manual intervention, ensuring that the cluster is always running on the most secure and stable version of Kubernetes.
