In the new rehosted cloud model, hardware
you previously managed yourself is now
managed by the cloud provider. All other
aspects of the workload or application
remain the same. This is the most popular
migration approach because it lets
organizations move quickly, with little risk
or impact, and receive immediate benefits.
It also reduces the total cost of ownership
(TCO) faster, enabling investment back into
the migration process to evolve through
the model.
How do you approach cloud migration? Chapter 02 8
Figure 1: Rehosting is one of several cloud operating models that can be used for migration.
Rehosting is also referred to as "lift and
shift." This stage entails migrating your
applications and virtual machines as-
is to the cloud. By simply shifting your
current server environment straight to
infrastructure as a service (IaaS), you reap
the benefits of cost savings, security, and
increased reliability (Figure 1).
