Contextualization: Providing One-click Virtual Clusters


  • Kate Keahey, ANL
  • Tim Freeman, University of Chicago


As virtual appliances become more prevalent, we encounter the need to stop manually adapting them to their deployment context each time they are deployed. We examine appliance contextualization needs and present an architecture for secure, consistent, and dynamic contextualization, in particular for groups of appliances that must work together in a shared security context. This allows for programmatic cluster creation and use, as well as mitigating potential errors and unnecessary charges during setup time. For portability across many deployment mechanisms, we introduce the concept of a standalone context broker. We include a description of the current implementation of the entire architecture using the Virtual Workspaces toolkit, showing real-life examples of dynamically contextualized grid clusters.
