Figure 7.4 Processes, once analyzed, may reside on cloud computing platforms
as needed to support the business. Some processes exist on-premise, some in the
clouds, and some span both on-premise and cloud-based systems.
hosted, depending on the requirements of the architecture. This is a very
simple concept. However, figuring out which processes to move and where to
put them is a more complex issue that we cover in more depth in Chapter 10,
“Defining Candidate Data, Services, and Processes for the Clouds,” and
Chapter 11, “Making the Move to Cloud Computing.” Keep in mind that
while processes need to run someplace, either on-premise or within the
clouds, processes are always able to touch services, and sometimes data, that
exist anywhere in the architecture, including on-premise and cloud-based
platforms. Therefore, they can exist wherever they need to exist, and you can
leverage them to bind together all services that are network accessible.
Note that while we can typically host data and services only on single
platforms—on-premise or cloud-based—in the world of BPM, we may have
processes that span platforms, binding together services and data between
cloud-based and on-premise systems. Moreover, these processes can be interplatform—cloud-based
and on-premise—and they can span across many
