In closing, some questions you should ask yourself…Who owns the data especially in a situations where there is shared access? What are the risks i.e. foreign governments or subpoenas?

Who is accountable/responsible for regulatory audits? (will your providers be subject to audit?)subject to audit?)

How detailed are your SLAs with your providers and do they cover all contingencies? i.e. access, loss, theft, audits, etc.

How will you secure any and all exposed APIs either to key applications or management systems?

Do you trust your providers security model or accreditation? Are you willing to give up control based on how they isolate/zone? Are hypervisor risksgive up control based on how they isolate/zone? Are hypervisor risks acceptable for production? Is encryption required for data in transit and at rest?

How will regulations constraint your use of cloud resources i.e. in-countryHow will regulations constraint your use of cloud resources i.e. in country data

How will you integrate management systems from multiple 3rd parties to enable an end to end view of service?

What management standards are you ready to adopt i.e. libcloud, WSDM, WS-Management, etc.
