4. Grid User Wish-List Who cares where it is? Who cares where it is?  It must always be available when I need it Make it secure Make it secure  no one can steal my data  no one can pretend to be me  don’t tell me who I will/can trust Choose secure, fast, cheap resources Choose secure, fast, cheap resources Don’t make me manually copy stuff around Don’t make me manually copy stuff around Don’t make me learn a new OS Don’t make me learn a new OS I don’t want errors I don’t want errors  If errors occur, tell me in plain English how I can avoid them next time Don’t bother me with the details Don’t bother me with the details Darnit, make my life easier !

5. Grid Research at UVa Legion: Grid OS Legion: Grid OS  Process creation and control  Distributed file system (LegionFS)  Security  Resource management and accounting  Programming model  Support for heterogeneity: policy and mechanism Hmmm… interop? Hmmm… interop?

6. Enter Web Services Web Services Web Services  “Semantically encapsulate discrete functionality”  Loosely coupled, reusable components  XML, SOAP, WSDL, UDDI, etc.  Broad industrial support: Microsoft, IBM, Sun, BEA, etc. Open Grid Services Architecture (OGSA) Open Grid Services Architecture (OGSA)  Combine Grids (Globus, Legion) with Web Services (?)

7. OGSI.NET Hosting environment for Grid Services based on Microsoft Web Services approach Hosting environment for Grid Services based on Microsoft Web Services approach  Leverage.NET Framework, VS.NET, ADO.NET, …  Evaluate Do Web Services give us everything we need to do Grids?  Contribute Here’s what we need added to WS-Trust; here’s how interop fails (e.g., SUN, IBM, Microsoft, Avaki, etc.)

8. Web Services Enhancements Add-on to VS.NET and.NET Framework Add-on to VS.NET and.NET Framework  WS-Security  WS-Policy  WS-SecurityPolicy  WS-Trust  WS-SecureConversation  WS-Addressing
