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.

Dedicated Hosts on Outposts now allows you to specify the AssetID associated with a physical server in your Outposts rack when allocating a new Dedicated Host using the EC2 Console, AWS Command Line Interface (AWS CLI), or an Amazon CloudFormation template. You may specify multiple target AssetID’s for allocating more than one host. You can also view the Asset ID associated with an allocated Dedicated Host in Outposts using EC2 Console or the EC2 describe-hosts API.

EC2 Dedicated Hosts on Outposts simplify bringing your existing software licenses and workloads requiring a dedicated physical server to the cloud. You can benefit from the flexibility and cost efficiency of using your eligible software licenses that are bound to VMs, sockets, or physical cores on Dedicated Hosts. In addition, with Dedicated Hosts you can exercise granular EC2 instance placement control based on your business needs.

This feature is available for Dedicated Hosts on AWS Outposts connected to all AWS Commercial Regions. It is not yet available in AWS GovCloud and China regions. To learn more, visit the Dedicated Hosts on AWS Outposts User Guide.
