Migrate Chapter 04 15
Driving application innovation
As you migrate your existing VMs to Azure,
it's also the perfect time to continue on the
path to application modernization.
Why look at cloud optimization so
soon after migrating? To get more cost
benefits through reduced management
and operating expenses. By moving to
platform as a service (PaaS), you can save
an additional 15–20 percent or more by
migrating workloads and applications—
over and above the savings you're making
today with IaaS (Figure 5).⁵
The PaaS services of immediate interest are
container, app, and database services
Tools for migration
The migration of servers and virtual
machines is different for everyone, but
multiple tools are available to support your
needs. These tools include the Microsoft-
provided Azure Site Recovery and third-
party tools.
