How can a SysOps Administrator achieve this while maintaining the security of the application?
Create an encrypted Amazon Machine Image (AMI) of the instance and make it public to allow the other account to search and launch an instance from it.
Create an AMI of the instance, add permissions for the AMI to the other AWS account, and start a new instance in the new region by using that AMI.
Create an AMI of the instance, copy the AMI to the new region, add permissions for the AMI to the other AWS account, and start new instance.
Create an encrypted snapshot of the instance and make it public. Provide only permissions to decrypt to the other AWS account.
Explanations:
Making an AMI public exposes it to anyone, which is a security risk. AMIs should be shared privately with the other account.
While this option shares the AMI between accounts, it does not account for moving the AMI across AWS regions. AMIs must be copied to the new region first.
This option correctly involves creating an AMI, copying it to the new region, and then sharing it with the other account. This ensures the security and portability of the instance.
Sharing a snapshot and making it public introduces a security risk by exposing the data. It is not recommended to make snapshots public, even with restricted decrypt permissions.
I arrange that the answer is:
Create an AMI of the instance, copy the AMI to the new region, add permissions for the AMI to the other AWS account, and start new instance.
