## AI overview

This tutorial presents a Burst to Region pattern for AWS Outposts workloads. When an Outposts rack reaches its fixed compute capacity, the pattern launches Amazon EC2 instances in the parent AWS Region, shifts traffic gradually, and returns traffic to local instances when capacity recovers. It uses CloudWatch, SNS, Lambda, EC2 Auto Scaling, Elastic Load Balancing, and EventBridge, trading increased latency for continued availability during capacity events.

## Source excerpt

AWS Outposts brings AWS infrastructure into your data center with low latency and data locality. But an Outposts rack has fixed compute. Learn how to build a Burst to Region pattern that overflows workloads to Amazon EC2 in the parent Region when local capacity is exhausted.
