As it described that the service model of cloud can be Saas, Paas or Iaas. Sometime two or more Saas need to be integrated. In that case how integration testing is performed?
What are the differences between integration testing in cloud and traditional PC based system?
Though Software testing occurs or should occur, during multiple phases of the construction of a software system. Typically the software development methodology determines both the kind of testing, and the phase during which testing is done. Hence Integration testing is focused at the verification of the interactions between the components of the system. The components are typically subjected to unit testing before integration testing starts. So we can say that strategy that determines the order in which components should be combined usually follows from the architecture of the system.

PaaS is the development or deployment platform used for your JEE or similar app stack. So, testing is no different than if it were real hardware, or that is the developer's expectation. In reality, you have less control than an IaaS. You do (or should be able to) control the app container, its version, container version, etc. Most conventional testing and integration translates to a PaaS. Think of it as .NET platform, JEE platform, NodeJS platform, etc. You self-service what platform you need.
IaaS is like google files, google compute engine, or cloud files. You use infrastructural components, such as cpu, disk, network via RESTful API interfaces, for example. You control the entire stack, including the OS, RESTful API versions, etc. For example, I used virtual box or vmware to stand up development environments for JEE, NodeJS, python, etc. Integration testing is under my complete control, including how apps talk to each other through the network, within the constraints of the virtual box/vmware stack within my overall environment.
SaaS are like cloud apps, such as google apps, salesforce, and citrix gotomeeting. Integration testing here depends largely on the cloud app capabilities.
Another difference testing in the cloud versus the PC is one can scale testing more effectively in the cloud. I also have found performance during testing may be improved simply because none of my office apps are active. But if you have a dedicated test machine, that may not be so important.
Cloud present more challenges to testing in general and not only integration testing.

Test as a Service (TaaS) is another outsourcing business model that can be classified as a further subgroup of SaaS. There are particularly three further coherent sub-models that are part of this service model:
- Functional Testing as a Service
- Performance Testing as a Service
- Security Testing as a Service
