AWS Elastic Beanstalk supports Capacity Rebalancing for Amazon EC2 Spot Instances

AWS Elastic Beanstalk now supports Capacity Rebalancing for [Amazon EC2 Auto Scaling groups (ASG)](https://docs.aws.amazon.com/autoscaling/ec2/userguide/AutoScalingGroup.html). This feature reduces [Spot Instance](https://docs.aws.amazon.com/whitepapers/latest/cost-optimization-leveraging-ec2-spot-instances/cost-optimization-leveraging-ec2-spot-instances.html) interruptions to customers’ applications. When enabled, ASG Capacity Rebalancing is designed to automatically attempt to replace Spot Instances in an Auto Scaling group before they are interrupted. Customers can enable Capacity Rebalancing on an existing EC2 Auto Scaling Group using the [Elastic Beanstalk Console](https://console.aws.amazon.com/elasticbeanstalk/) or the [aws:autoscaling:asg](https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/command-options-general.html#command-options-general-autoscalingasg) namespace configuration option. For more information, see [ASG for Elastic Beanstalk environment](https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.managing.as.html#environments-cfg-autoscaling-spot) in the AWS Elastic Beanstalk Developer Guide.
