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?)
    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 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-country
                                                                     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,
9
    WS-Management, etc.
Thank You

  • 9. 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?) 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 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-country 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, 9 WS-Management, etc.
