Amazon EC2 Dedicated Hosts now support targeted allocations in AWS Outposts rack

You can now target allocation of Amazon EC2 Dedicated Hosts to specific AWS Outpost hosts. With targeted Dedicated Host allocations, you can control the deployment location of your workloads on specific Outposts racks. This allows you to allocate Dedicated Hosts on physical servers closely located on the same Outposts rack to achieve low latency goals. You can also use this feature to spread workloads on hardware across multiple Outposts racks for additional resiliency.
