AWS Elastic Beanstalk added support for Capacity Rebalancing for Amazon EC2 Spot Instances.

Release date: August 9, 2021

Changes

Spot Instances are an Amazon EC2 instance purchasing option that can lower your costs significantly. Although they are a cost-effective option, your requirements must be flexible regarding when your applications run and whether they can be interrupted.

Starting today, Elastic Beanstalk offers the Capacity Rebalancing feature for Amazon EC2 Auto Scaling groups. This feature reduces Spot Instance interruptions to your applications. With ASG Capacity Rebalancing enabled, Amazon EC2 automatically attempts to replace Spot Instances in an Auto Scaling group before they are interrupted.

You can enable Capacity Rebalancing on an existing EC2 Auto Scaling Group using the Elastic Beanstalk Console or the aws:autoscaling:asg namespace configuration option. For more information, see Auto Scaling group for your Elastic Beanstalk environment in the AWS Elastic Beanstalk Developer Guide.
