Amazon EKS adds support for EC2 Spot Instances in managed node groups

Amazon Elastic Kubernetes Service (Amazon EKS) now supports creating and managing Amazon Elastic Compute Cloud (Amazon EC2) Spot Instances using Amazon EKS managed node groups following Spot best practices. This enables you to take advantage of the steep savings and scale that Spot Instances provide for interruptible workloads running in your Kubernetes cluster. Starting today, you can supply multiple instance types when creating a new Managed Node Group, further allowing you to enhance availability of your applications running on Spot.
