Service Classifications • Essential – 24x7, 15 minute recovery • Health/Safety – E911, Paging, … • Critical – 24x7 - <2 hour recovery • SAP, Email, Core University Websites • Sensitive – 24x7 / 8-5M-F – 2-4 hour recovery • SISS, Lecture Capture, ... • Tolerant – 8-5 M-F – 1 Business day recovery • Departmental websites,

  4. System Inter Dependencies Create Risks • Real Time • Network • Authentication and Authorization • Shibboleth, Active Directory, Kerberos, LDAP • Domain Name Services (DNS) • Back End Services and Integrations • Provisioning, PeopleSoft, SAP

  5. Cloud Challenges • More reliance than obvious on Duke infrastructure • Network Latency/Geography • Network Connectivity/Routing • Services Shared With Other Customers • Required Updates to Current Software Version

  6. Cloud Benefits • Geographical Distribution • Economies of Scale • Expertise or Commodity • Speed (Deploy/Update/Fix) • Especially if we don’t customize • Features • Required Updates to Current Software Version

  7. Lessons Learned So Far • Visibility • Openness of Partner • Network Connectivity • Can we leverage what we own/control? • Internet 2 • Specific Peering Relationships/NCREN • Multi-Tenancy • Where are we big enough or different? • Where are we small enough or the same?

  8. Lessons Learned (cont.) • Integration is a challenge but have same challenge on campus • Shibboleth solves some problems • Consistent AD/LDAP service solves some problems • Uniform services across campus solves some more

  9. $64,000 Question • Why would we want to run services outside of Duke? • What do we gain? • What do we give up? • Are we thinking about this in the right way? • Do we run them in the Cloud, at Duke or Hosted

  10. Possible Decision Criteria:

  11. Question 1 • Is the service a commodity? • Does Duke need to do it differently? • Does Duke have a different reliance on it than others? • Does Duke add value when we do it ourselves? • Can Duke get to the same economies of scale as the service providers? • Do we gain control of how we make ongoing investments into the service?

  12. Question 2 • Is it part of what makes Duke, Duke? • Do we get control to make it do what Duke needs? • Do we get control to keep it running as Duke needs? • Is it core to the Duke campus experience? • For Students? • For Faculty and Researchers?

  13. Question 3 • What is the business value to Duke • Are we the same as other customers? • What makes us different? • What are the impacts of outages on Duke • Reputational, Revenue Loss, Liability, … • Does Duke have the talent and can it keep the talent? • Do we want to rapidly introduce change (or force change)?

  14. Question 4 • What are the challenges to implementation? • Is it tightly integrated with many Duke systems? • Do we have the expertise and will we need the expertise long term? • Does it have strict networking requirements • Latency, bandwidth, jitter • How much customization is needed to meet Duke needs? • Can Duke change how it does business or should we customize?

  15. Question 5 • What are the security implications • Regulated? • FERPA • HIPAA • Etc.
