Inside a public or private cloud several SaaS can interact with each other or with other enterprise application. My question is what are the scope or aspect of integration testing in Cloud?
Well that depends on what your testing requires and if the data or app has any requirements around it, If your thinking along the lines of continuous delivery or Agile than the biggest concern is data\application security between tenets on the system, the fabric that it connects to and the SLA that the cloud provider or your private cloud can off, IE can it scale fast enough, can it be self managed, can the app be developed to take advantage of those features.
