Instance placement and tenancy - 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).

Instance placement and tenancy

Use placement settings to control where Image Builder launches your build and test instances. By default, Amazon EC2 instances run on shared tenancy hardware, which means multiple Amazon Web Services accounts might share the same physical server. You can change the tenancy to run on single-tenant hardware or a Dedicated Host. You can also pin instances to a specific Availability Zone.

For the placement field names, their valid values, and constraints, see Placement in the EC2 Image Builder API Reference.

Note

Mac instances require a Dedicated Host. Set tenancy to host for macOS images. If your Dedicated Host has auto-placement enabled and you don't specify a hostId or hostResourceGroupArn, Amazon EC2 finds an available host for you. For more information, see Auto-placement in the Amazon EC2 User Guide.
