Rehost

This strategy involves moving applications from the on-premise environment to the cloud without modification. It is commonly used to migrate large-scale legacy applications to meet specific business objectives such as an accelerated product launch timeline.The Rehost strategy sounds simple, and it is. There are mature tools on AWS which allow you to carry it out with low effort. The downside is that with no changes to the application, it has limited ability to take advantage of the cloud-native environment.
