self-provisioned hybrid clouds
Virtual Organizations are dynamic entities that consist of individuals and/or institutions established around a set of resource-sharing rules and conditions. The VO may require the use of on-site (local) and off-site (public) compute resources that can be leased or autonomically provisioned, based on workload and site policies. Virtual Organization Clusters provide the necessary computing infrastructure by building upon existing physical grid sites without disrupting the existing infrastructure or requiring any engagement from end users. VOCs also separate the physical and virtual administrative domains and thus encourage more sites to participate in the resource sharing and hosting. The VO can relinquish the compute resources based on job completion or other operational parameters such as cost. This paper expands on previous work with the Virtual Organization Cluster Model by demonstrating its scalability across multiple grid sites with the use of a structured peer-to-peer overlay networking system. A novel approach by which the model is extended to lease-based systems, such as the Amazon Elastic Compute Cloud (EC2), is introduced.
