● ● Workloads is sunset and has limited value to move and modernize.
●● ●● ●●●●● ●● Rehost on a new deployment of the existing platform. This takes a short amount
of time, and has low migration costs, but also has little business benefit as this is
considered business as usual and not modernization.
●●●●●
Retaining the workload on the existing platform has virtually no time or cost, but
typically has a more expensive cost to operate than open source solutions, and
doesn’t provide the business benefits of a hybrid solution to provide developers
the flexibility to build new applications with modern patterns.
●● ● ●●● ●●●●
One hyper-converged, open source, VM & container platform reduces operating
costs; business is benefited by having the ability to deploy VM solution with
modern containers to drive innovation. Self-service for VMs drives availability
of platform for business innovation.
●●●● ●●● ● ●●●●●
As legacy applications are containerized, they can be iteratively refactored to
realize decreased time to market for new development, leveraging concepts like
microservices strategies. Refactoring may also include upgrading technologies
to lighter weight, modern, and more cost effective open source solutions.
●●● ●●● ●● ●●●●
For commercial off the shelf solutions, moving to containers may be realized
through upgrading the vendor product to the latest version. While this takes
time to realize and cost, it can be aligned to end-of-life schedules for COTS
providers.

to modernizing platforms and workloads to OpenShift for containers and virtual machines.
