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

134 Chapter 7 Working from Your Processes to the Clouds
What must be understood is that data, services, and processes may move
between on-premise and cloud-based systems as needed to support the business
and the architecture. The trick, and the reason you are reading this
book, is to determine which ones should reside where, which we cover extensively
in Chapters 10 and 11.
Figure 7.6 depicts our process for defining the process model, which is
the next step in our methodology, so we can better understand our problem
domain before relocating processes from on-premise systems to cloud-based
systems, as needed.
Understand the processes means that we look at the processes within our
problem domain that are automated or not automated, define them at a high
level, and add them to a list of candidate processes. The idea is that we list pro-

Figure 7.6 The process of creating a process model looks very much like it did in
designing the services model in Chapter 6, because services and processes share
many of the same patterns. However, processes are different enough from services
to require their own steps.
