Discussion Points 1.What types of virtualization technologies are likely to be of most interest to PRAGMA members 2.What is the most important aspect of Virtualization/Cloud to you? 3.What is fundamentally different about Cloud computing vs. Grid Computing 4.What elements of the Grid SW stack should go forward as the community moves towards cloud computing? Which should be dropped. 5.What are your predictions about virtualization and cloud computing.
A Straw mans view to PRAGMA Congratulations on our Victories! More time on applications More scientists involvement Less Toy apps less time on system admin Globus, thank you!, switch to other business GSI, Easy-rider Provide sustainable platform of supporting E-Science (or Cyberinfrastructure) Probably, each app requires different configuration (SW, MW, ver-match, ) Hard to maintain an omnipotent pltfm
What types of virtualization technologies are likely to be of most interest to PRAGMA members Instant deployment/provisioning of application hosting environment provisionors, resource schedulers, CS challenge: Data/Storage Migration What is the most important aspect of Virtualization/Cloud to you? Save your time from tedious system management Quick scale-out CS Challenge: multi-site virtual clusters
What is fundamentally different about Cloud computing vs. Grid Computing Inappropriate discussion of religions Grid: technology oriented, Cloud: Business oriented Cloud=(Grid+SOA)-OGSA What elements of the Grid SW stack should go forward as the community moves towards cloud computing? Which should be dropped. Fw: GSI, identity management Fw: Data federation Fw: resource management Fw: SLA
