Work with Dedicated Instances

You can create a VPC with an instance tenancy of dedicated to ensure that all instances launched into the VPC are Dedicated Instances. Alternatively, you can specify the tenancy of the instance during launch.

Create a VPC with a dedicated instance tenancy

When you create a VPC, you have the option of specifying its instance tenancy. If you launch an instance into a VPC that has an instance tenancy of dedicated, your instance is automatically a Dedicated Instance, regardless of the tenancy of the instance.

For more information about creating a VPC and choosing the tenancy options, see Create a VPC in the Amazon VPC User Guide.

Launch Dedicated Instances into a VPC

You can launch a Dedicated Instance using the Amazon EC2 launch instance wizard.

Change the tenancy of an instance

You can change the tenancy of a stopped instance after launch. The changes that you make take effect the next time the instance starts.

Note

For T3 instances, you can't change the tenancy from dedicated to host, or from host to dedicated. Attempting to make one of these unsupported tenancy changes results in the InvalidTenancy error code.

Change the tenancy of a VPC

You can change the instance tenancy of a VPC from dedicated to default after you create it. Modifying the instance tenancy of the VPC does not affect the tenancy of any existing instances in the VPC. The next time you launch an instance in the VPC, it has a tenancy of default, unless you specify otherwise during launch.

Note

You cannot change the instance tenancy of a VPC from default to dedicated after it is created.

You can modify the instance tenancy of a VPC using the Amazon CLI, an Amazon SDK, or the Amazon EC2 API only.

Command line
To modify the instance tenancy attribute of a VPC using the Amazon CLI

Use the modify-vpc-tenancy command and specify the ID of the VPC and instance tenancy value. The only supported value is default.

aws ec2 modify-vpc-tenancy --vpc-id vpc-1a2b3c4d --instance-tenancy default
