Capacity management

You can monitor Outpost EC2 instance pool utilization in the AWS Management Console and via Amazon CloudWatch metrics. Contact Enterprise Support to retrieve or change the slotting layouts for your Outposts.

You use the same instance auto recovery and EC2 Auto Scaling mechanisms to recover or replace instances impacted by server failures and maintenance events. You must monitor and manage your Outpost capacity to ensure sufficient spare capacity is always available to accommodate server failures. The Managing your AWS Outposts capacity using Amazon CloudWatch and AWS Lambda blog post provides a hands-on tutorial showing you how to combine AWS CloudWatch and AWS Lambda to manage your Outpost capacity to maintain instance availability.

Managing AWS Outposts capacity with Amazon CloudWatch and AWS Lambda

  • Configure your EC2 instances in Auto Scaling groups or use instance auto recovery to restart failed instances.

  • Automate capacity monitoring for your Outpost deployments and configure notifications and (optionally) automated responses for capacity alarms.
