The document discusses the private cloud architecture being implemented at the University of the Witwatersrand. It outlines plans to build a private cloud infrastructure using open source technologies like OpenStack, Fedora, iRODS and Zimbra. The cloud will provide scalable compute and storage resources along with hosted services and a digital archive. Key steps are identifying support staff, collaborating with technology partners, and having the initial infrastructure in place by mid-November.

1. Private Cloud Architecture Moving Wits beyond the cutting edge Prof Derek W. Keats Deputy Vice Chancellor (Knowledge & Information Management) The University of the Witwatersrand, Johannesburg http://kim.wits.ac.za [email_address]

2. Innovation Innovation Innovation driven Where are there opportunities to create synergy, leading to innovation? Process Technology Support (people)

3. Risk without ecosystem Safe, proven, mature old technologies Mature but relatively new technologies We help to lead technology trends We create and use new technologies before anyone else Option 1 Option 2 Option 3 Option 4 Option 5 The cutting edge

5. Capable of virtualization to run multiple systems and take advantage of better use of CPU cycles and storage Massive clusters of low cost commodity computers - Compute cloud (e.g. Amazon Elastic Cloud) - Data cloud (e.g. Amazon S3) - Public cloud - Private cloud

16. Management of the cloud must be via easy to use interfaces, and there should not be excessive systems administration costs

17. Compute and storage systems must be fully scalable by adding additional elements

18. There should be a capabilty to cost and charge for hosted virtualized systems

21. e.g. Sun Microsystems (Cloud)

24. Teleconference with engineer and others from Sun microsystems to determine feasibility

25. Compiling budgets

26. Will hold a planning meeting with Sun soon

27. Plan to have in place by mid-November
