The NSF “Open Cloud Testbed” (OCT) project is building and supporting a testbed for research and experimentation into new cloud platforms – the underlying software which provides cloud services to applications. Testbeds such as OCT are critical for enabling research into new cloud technologies – research that requires experiments that potentially change the operation of the cloud itself. In this video, Michael Zink describes OCT and the development of a testbed for the research community exploring next-generation cloud platforms.
