Which migration strategy involves a simple transfer of application resources from an on-premises data center to the AWS Cloud?

The migration strategy that refers to a straightforward transfer of application resources from an on-premises data center to the AWS Cloud is known as "rehost" or "lift and shift." This approach allows organizations to move their existing applications to the cloud with minimal changes to the underlying architecture. It is particularly advantageous for businesses looking to quickly migrate to AWS without incurring significant costs or resources associated with redesigning their applications.

In a lift-and-shift migration, the applications run in the same way in the cloud as they did on-premises, taking advantage of cloud resources, such as scalability and flexibility, without requiring the application to be rewritten or reconfigured significantly. This strategy is often used as a first step in a broader cloud strategy, allowing organizations to see the benefits of cloud computing while planning for future migrations or improvements.

Other strategies involve more complexity, such as modifying or fully redesigning applications, which can require substantial effort and resources, making rehost a simpler and quicker option for initial cloud adoption.
