Placement - EC2 Image Builder
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Placement

By default, EC2 instances run on shared tenancy hardware. This means that multiple Amazon Web Services accounts might share the same physical hardware. When you use dedicated hardware, the physical server that hosts your instances is dedicated to your Amazon Web Services account. Instance placement settings contain the details for the physical hardware where instances that Image Builder launches during image creation will run.

tenancy

The tenancy of the instance. An instance with a tenancy of dedicated runs on single-tenant hardware. An instance with a tenancy of host runs on a Dedicated Host.

If tenancy is set to host, then you can optionally specify one target for placement – either host ID or host resource group ARN. If automatic placement is enabled for your host, and you don't specify any placement target, Amazon EC2 will try to find an available host for your build and test instances.
