Hi there, we are researchers from University of Wisconsin Madison. Our research is about cloud computing and system security. Currently we are surveying on a few facts about how cloud tenants operate their services. The purpose of the survey is to justify a few design questions so that our research can be practical for real world applications. I am wondering if you could kindly help us by filling out a few simple general questions hosted on Typeform: https://yanzhai.typeform.com/to/sZ0Yjm . The survey is fully anonymous. Any of your feedback would be greatly appreciated! Thank you very much! Yan
