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.

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
