Abstract

Advances in server virtualization offer new mechanisms to provide resource management for shared server infrastructures. Resource sharing requires coordination across self-interested system participants (e.g., providers from different administrative domains or third-party brokering intermediaries). Assignments of the shared infrastructure must be fluid and adaptive to meet the dynamic demands of clients. This thesis addresses the hypothesis that a new, foundational layer for virtual computing is sufficiently powerful to support a diversity of resource management needs in a general and uniform manner. Incorporating resource management at a lower virtual computing layer provides the ability to dynamically share server infrastructure between multiple hosted software environments (e.g., grid computing middleware and job execution systems). Resource assignments within the virtual layer occur through a lease abstraction, and extensible policy modules define management functions. This research makes the following contributions: • Defines the foundation for resource management in a virtual computing layer. Defines protocols and extensible interfaces for formulating resource contracts
