AWS Lambda Updates

AWS Lambda now supports AWS Graviton5-powered C9g, C9gd, M9g, and M9gd instances on Lambda Managed Instances. You can now run your Lambda functions on the latest generation of Graviton processors, delivering up to 25% better compute performance compared to Graviton4-powered instances.

Lambda Managed Instances lets you run Lambda functions on your AWS EC2 instances while maintaining Lambda's operational simplicity. With Lambda Managed Instances, you can access specialized compute configurations and drive cost efficiency through EC2 pricing advantages, without managing infrastructure.

What to do

  • Specify the desired Graviton5 instance type (C9g, C9gd, M9g, or M9gd) when creating a capacity provider.
  • Set the instance type to default for Lambda to automatically include Graviton5 instances based on your function’s configured architecture, memory size, and memory-to-vCPU ratio.
