Cloud Computing and SOA Convergence in Your Enterprise: A Step ...

CHAPTER 10
Defining Candidate Data,
Services, and Processes
for the Clouds
Chapter 10
When there’s snow on the ground, I like to
pretend I’m walking on clouds.

Now we’re cooking. We have an information, service,
process, and governance understanding of our problem
domain, and we understand how to approach testing.
Now it is time to identify the data, services, and processes
that are good candidates for cloud computing. In the
next chapter, we move them out there as well as define
the end-state architecture and how to extend our SOA
out to the clouds.
Keep in mind that we are doing a bit of a distributed
computing balancing act now, deploying services, processes,
and data on platforms that make the most sense,
and we are doing so in the context of SOA. What we are
defining here is a mere instance of the architecture, and if
it is defined and deployed correctly, we should be able to
move our services, processes, and data between onpremise
and cloud-based systems without a great deal of
difficulty.
The way to get SOA using cloud computing architecture
right, right out of the gate, is to identify those services,
processes, and data that are good candidates for cloud
computing. Once those services are in the clouds, we are
likely not to relocate them anytime soon. Moreover, we
