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

CHAPTER 9
Testing from SOA
to the Clouds
Chapter 9
Let’s just say I was testing the bounds of society.
I was just curious.
—Jim Morrison (1943–1971)
At this point, we have a service-, process-, and informationlevel
understanding of our problem domain, and we have
a governance model created as well. Now it is time to explore
the unique testing requirements that SOA brings
when used with cloud computing. We focus on testing
for a few core reasons:
The mix of on-premise and cloud computing systems
and services creates a complex and widely distributed
architecture that is also complex to test and
requires some new thinking. We are extending our
testing to systems we do not own or control. While
this is not the first time we have included systems
outside of the enterprise within our testing domain,
typically, we have never leveraged those systems as vital
architectural components. We are breaking some
new ground here.
The testing must occur at many levels, including the
user interface, services, governance, processes, and so
on, and we need an approach strategy for this multilevel
testing requirement.
