Gu Receives FRPD Award to Study Large-scale Virtual Hosting Infrastructures
Dr. Helen Gu, assistant professor of computer science at NC State University, has been awarded $6,000 by the NC State Faculty Research and Professional Development (FRPD) fund to support her research proposal titled “Automatic 24x7 Health Management For Large-Scale Virtual Hosting Infrastructure.”
The award will run from July 1, 2008 through June 30, 2009.
Research Abstract - Large-scale virtual hosting infrastructures have become important platforms for many systems such as virtual computing lab, corporate data centers, and multi-tier web servers. However, system administrators are often overwhelmed by the tasks of correcting various system health problems such as performance bottlenecks, resource hotspots, service level objective (SLO) violations, and various software/hardware failures. We are addressing this challenge through three synergistic techniques: i)intelligent information management system that can adaptively and selectively collect important information and provide query support with low monitoring cost; ii) context-aware distributed anomaly prediction that can raise advance alerts for impending system anomalies; and iii) just-in-time anomaly remediation and diagnosis tools that can dynamically alleviate impending anomalies and produce informative diagnosis reports to the system administrator by applying time-traveling executions and analysis techniques on abnormal system components. Our research will lead to a fundamentally new online health management approach that offers a more cost-effective self-healing solution for large-scale virtual computing environments than previous reactive or proactive approaches. We are developing the prototypes of the proposed system, and will evaluate it on the VCL infrastructure at NCSU.
