Middleware challenges
Virtual Machine = process (VM monitor) + data (VM image and user files)
Image and Data Management
Creation, storage, and transfer of VM images for dynamic instantiation, and user data
Resource Management
Application and resource perspectives
Virtual Networks
Computing “In-VIGO” (In Virtual Grid Organizations)
Data management: Grid virtual file systems
Seamless access to decentralized storage services of a grid
User-transparent virtual file systems created on-demand on top of NFS (V2,3)
Supports unmodified binary applications and native O/S clients, servers
Virtualization:
Polymorphism
Manifolding
Multiplexing
Virtual resources
Physical resources
Resource management
Relational database queries
Resource control via real-time schedules
“Classic” Virtual Machines (VMs)
Many, distinct O/Ss that multiplex a physical resource
E.g. VMware (x86), IBM z/VM (S/390)
Prototype and applications
InVIGO middleware beta (Spring 2003)
Java, Globus, SQL, Apache, VFS
Netcare, nCn, Digital Government, BMI, LSS
Grid computing with VMs1
Security, isolation
Customization, legacy support
Resource control, site independence
Wide-area Testbed
