When an enterprise migrates an application to the cloud as-is, without making any modifications, this process is called Rehosting.

Explanation

Rehosting, often referred to as "lift and shift," involves moving existing applications to the cloud without changing their architecture or code. This allows businesses to take advantage of cloud resources quickly while delaying any necessary changes or optimizations for later.

In contrast:

• Reducing typically refers to minimizing resources or capacities.
• Retired implies decommissioning or shutting down applications altogether.
• Refactor involves modifying the application's code and architecture to better fit the cloud environment and take full advantage of cloud services.

Thus, the correct answer is Rehosting.
