Why SOA using Cloud Requires a New Approach to Testing

SOA Governance is a Concept used for Activities Related to Exercising Control over Services in a Service-Oriented Architecture (SOA)

One viewpoint, from IBM and others, is that SOA governance is an extension (subset) of IT governance which itself is an extension of corporate governance.
So, why is SOA making use of cloud computing so unusual that we need a alternative technique to testing? As I have actually been stating on this blog site, very many of the exact same patterns around testing a distributed computing system, such as a SOA, are appropriate here. We are not asking you to test that in a different way; only to consider a few brand-new possibilities.
There are some clear screening differences to note when cloud computing enters the mix.Initially, we do not own nor control the cloud computing-based systems, therefore we have to deal with what they offer us, consisting of the restrictions, and typically can’t change it. Hence, we can’t do some types of testing such as finding the saturation points of the cloud computing platform to identify the upward constraints on scaling, or effort to figure out ways to crash the cloud computing system.
That kind of testing might get you a nasty email. Or, white box testing the underlying platform or services, suggesting seeing the code, is also, not supported by most cloud computing service providers, but clearly something you can do if you possess and regulate the systems under test.



Second, the patterns of use are going to be various, including how one system interacts with another, from business to shadow. Typically, we test systems that are on-premise, and almost never ever test a system that we can not see nor touch. This consists of problems with Internet connectivity.Third, we are checking systems that are contractually obligated to offer computing service to our architecture, and hence we require a means to confirm that those services are being offered now, and into the future. Therefore, testing handles a legal element, because if you find that the service is not being delivered in the manner outlined in the contract, you can act.
Finally, cloud computing is fairly new. As such, IT is a bit suspicious about the absence of control. Extensive and well-defined testing, will eliminate most of those fears. We have to be hyper diligent to decrease the opportunities of failure, and work around the fear of what’s brand-new.
