Among the first entrants to the now widely practiced field of cloud computing, our group's early work concerned I/O virtualization, improved hypervisors, and then moved on to better understanding the behavior of virtualized applications and systems, in part through black box methods for monitoring and systems management. Online monitoring and data analytics -- monalytics -- are a key tool in that space, where we have developed new software infrastructure, techniques for detecting anomalous system behavior, in joint work with corporate partners that include HP Labs, IBM, Intel, VMware, and others. Managing such complex systems is another topic prevalent in our research, in part because we routinely run our own cloud infrastructures for use in teaching and research.
An important research stream pervading much of our work in the enterprise space concerns the online nature of many modern web and scientific applications, where we have worked with groups like IBM's System S team, have collaborated with HP Labs on the online processing of datacenter monitoring information, have been inspired by problems at Amazon, and continue to interact with colleagues at CMU and Intel as part of the Intel (Cloud ISTC).
