EC2 Auto Scaling announces warm pool support for Auto Scaling groups that have mixed instances policies

Starting today, you can add warm pools to Auto Scaling groups (ASGs) that have mixed instances policies. With warm pools, customers can improve the elasticity of their applications by creating a pool of pre-initialized EC2 instances that are ready to quickly serve application traffic. By combining warm pools with instance type flexibility, an ASG can rapidly scale out to its maximum size at any time, deploying applications across multiple instance types to enhance availability.

Warm pools are particularly beneficial for applications with lengthy initialization processes, such as writing large amounts of data to disk, running complex custom scripts, or other time-consuming setup procedures that can take several minutes or longer to serve traffic. With this new release, the warm pool feature now works seamlessly with ASGs configured for multiple On-Demand instance types, whether specified through manual instance type lists or attribute-based instance type selection. The combination of instance type flexibility and warm pools provides a powerful solution that helps customers scale out efficiently while maximizing availability.

The warm pool feature is available through the AWS Management Console, the AWS SDKs, and the AWS Command Line Interface (CLI). It is available in all public AWS Regions and AWS GovCloud (US) Regions. To learn more about warm pools, visit this AWS documentation.
