Post #153 (AWS) – EKS, Elastic Kubernetes Service

Posted on October 6, 2023October 6, 2023 by admin

We’ve talked about ECS, Elastic Container Service, which is Amazon’s offering for managing and running container images in AWS. If you would like an open source offering that can be used by multiple cloud providers, or you already have Kubernetes on premises and you want to migrate to AWS, then EKS is for you! It works very similarly to ECS and even supports similar deployment types such as fargate! Specifically the three deployment types you have are managed, self managed, and fargate. With managed EKS manages these nodes (EC2 instances) for you and they are connected to an ASG managed by EKS, on-demand and spot instances are supported here. Next up we have self managed, you create these nodes and connect them to an ASG which then manages them, this also supports on-demand and spot instances. Finally we have fargate which requires 0 management as no nodes need to be managed it simply just allows you to run your containers off of EKS. Important vocabulary distinction, pods typically are used when referring to Kubernetes, the equivalent in AWS ECS would be a task.
