Lift and Shift

Usually, cloud projects gravitate towards a new development using cloud-native capabilities, but in a large legacy migration scenario, where the organization is looking to scale its migration quickly, the need for Rehosting arise.

Rehosting is the process of moving your existing   physical and virtual servers to a solution based on Infrastructure as a Service (IaaS).

The key benefit of this approach is that systems can be migrated quickly without any modification to their architecture and is the  path usually taken by new companies.

Here,  you’re basically treating the cloud as just another data center, which means you’re not  getting the most out of the available cloud services.

For instance, let’s consider an  ASP.NET Web Application running on windows and you want to host it on AWS.

You  can create a Windows VM that meets the size requirements  and deploy the application, and with the change in DNS record you are pretty much ready to go live.

As simple as that.  But the drawback is that this solution isn’t highly available, or scalable, and it still requires you to manage OS patches.
