As well, Kubernetes label selectors allow for much easier ways of describing how containers consume networking and storage resources. ‘Pods’, ‘Deployments’, 'ReplicaSets' and 'Services' allow engineers to define containers within an applications in ways that would be cumbersome to replicate on ECS at scale.

On the other, there are costs to the simplicity of ECS that make EKS an attractive alternative for a number of reasons:įirstly, Kubernetes has a significantly more mature syntax for application definition.

On the one hand, ECS’s more limited feature set and seamless integration with other AWS services such as Elastic Load Balancing, Route 53 and CloudWatch makes it easy for businesses to quickly begin reducing their infrastructure management overhead and focus on shipping product faster and more safely. At bottom, the biggest difference between the two services is that ECS is a simpler and more basic container orchestration tool than EKS, which brings both advantages and disadvantages. There are few things to consider if you’re currently using ECS and are considering utilizing EKS. This approach makes scheduling containers onto clusters across availability zones and regions easy and fast. Like Kubernetes, Swarm and other container orchestrators, ECS enables users to write configuration files describing the containers that they need and deploy them onto regular EC2 instances with a special agent installed and IAM permission applied. We’re currently using Amazon’s ECS: what does EKS mean for me?Īmazon's EC2 Container Service, or ECS, is a cloud-native container management service that runs entirely on Docker and EC2. You can get more information on EKS from Jeff Barr's blog post here. Lastly, EKS can run in a VPC and fully supported AWS PrivateLink to keep all traffic between your EKS cluster and your other AWS resources completely within AWS. Kubernetes is automatically updated on these masters, and access credentials are managed by IAM instead of users having to create them on their own. Like Amazon's ‘classic’ Elastic Container Service offering, this is accomplished by allowing users to create Kubernetes workers managed by three centralized and highly-available Kubernetes masters through the AWS Console or Command Line Interface (CLI). While Kubernetes is an extremely powerful container orchestrator, provisioning, scaling, updating and monitoring these clusters manually is often time-consuming and difficult.Īmazon's Elastic Container Service for Kubernetes, or EKS, solves this by offering is a managed service that greatly simplifies the process of creating and using Kubernetes clusters in AWS. Kubernetes is a clustered container orchestration system that automates the creation, replication, scaling and management of Docker containers. If you asked yourself these questions after this announcement, then I am hoping that this short article helps sort some confusion out.

While this announcement is great news for those just getting started down the path to highly-scalable, cloud-native containerized platforms, this might leave those currently using ECS or their own managed Kubernetes clusters asking themselves: “What does this mean for me?”

Amazon also released AWS Fargate, a complement to their Elastic Container Service (ECS) that completely removes the infrastructure management required to run ECS clusters and makes containers a first-class resource. Dubbed Elastic Container Service for Kubernetes, or EKS, Amazon's offering simplifies the work of creating and managing your own Kubernetes cluster by enabling users to create and cluster their own Kubernetes worker nodes. Carlos Nunez 5 December 2017 What Do Amazon ECS Kubernetes Service and Fargate Mean for You?Īs many of us in this space have long-anticipated, Amazon has finally unveiled their answer to Google and Microsoft's Managed Kubernetes Services at their annual re:Invent conference in Las Vegas.
