Which process will have minimal impact on your application while complying with this requirement?
Create a new VPC with tenancy=dedicated and migrate to the new VPC
Use ec2-reboot-instances command line and set the parameter “dedicated=true”
Right click on the instance, select properties and check the box for dedicated tenancy
Stop the instance, create an AMI, launch a new instance with tenancy=dedicated, and terminate the old instance
Explanations:
Creating a new VPC with dedicated tenancy requires moving the instance to a completely new VPC, which can cause significant disruption to the application and would involve complex networking changes.
Theec2-reboot-instancescommand does not allow changing the tenancy of an instance. Tenancy cannot be modified by rebooting; it needs to be specified at launch.
Tenancy cannot be changed by right-clicking and selecting properties in the AWS Management Console. This option is not valid for modifying instance tenancy.
Stopping the instance, creating an AMI, and launching a new instance with dedicated tenancy is the correct process. This approach involves minimal impact as it ensures the instance is moved to dedicated hardware while preserving the application configuration.
