SOFTWARE ASSURANCE TESTING BEFORE RELEASING CLOUD FOR BUSINESS - A CASE STUDY ON A SUPERCOMPUTER GRID (XSEDE)

摘要

There is a dire need to determine when best to release operations with respect to CLOUD computing to commercial use. CLOUD computing operations centers are multiplying rapidly and offering services to their clientele who believe that they are getting a good deal. However, "devil in the details" is the lack of an assumed reliability where customers soon discover that the services promised or claimed are not offering expected service reliability. This CLOUD reliability testing for assurance purposes opens new avenues in a very critical area of cybersystems and information security defined to be "quantitative stopping rules in reliability and security testing". This is a new research paradigm worth undertaking when compared to the existing and conventionally qualitative or rule-of-thumb rules which do not lend themselves to probabilistic and cost-effective reasoning. A case study on XSEDE, a continental supercomputing grid to be the world's largest, will be studied and discussed.
