Bringing the Grid Home with G-ICING

Editor's Notes
- Good afternoon and Konichiwa Today I’ll be talking about G-ICING, an Installable File System for Windows that interfaces with a Grid-Backend. As this photo shows, G-ICING is intended to be a layer on top of the Grid intended to make the grid tastier ;-)
- Explosion of information systems has led to vast arrays of data stored in widely varying formats, locations, and subject to numerous access and privacy policies. Collected and housed in standalone data stores with little or no integration between systems. Definte interest in more integrations resources. Introduce the grid, integrating information across organizational boundaries. Requires tackling a wide range of issues including finding, naming and accessing, crossing firewalls, enforcing policies, et al. Grid was supposed to solve all this (move with slide)
- Simple and familiar - users should use a familiar paradigm. Users do not like to change the way they work, instead we should extend existing paradigms to interact with the Grid rather than vice versa COTS and legacy applications do not change. We must use something that they already use Performance, we just can’t die here Security – same shpeal Standards in order to interact with others People don’t want to be locked into one vendor. Help innovate on a grand scale since everyone can talk to each other Don’t have to develop same things more than once to take advantage of others sharing resources. Simple and familiar User Transparency Application Transparency We FORGET this criterion often Performance Users and applications don’t like to wait around all day Security Organizations need to enforce policies Normal users need it Based on Standards to allow interaction between different Grid infrastructures
- More FOCUS Talk about how people and applications are familiar with the filesystem interface. Talk about how the IFS transparently maps the Grid into the Windows file system (DO NOT GLOSS OVER SOS-KAY).

- Focus on more Inv Call Model
- Security – within the host G-icing relies upon Windows security to protection information between users of the same machine. Host-grid secuirty is complex. G-icing acts as a proxy for users. GIS prompts user for credentials and user is given a choice of using one of their certificates. GIS gets a signed delegated credential. Uses WS-Security* family of specifications and profiles.
- We knew would be slow. Overhead involved with WS is enormous. Multiple XML serialization and deserialization ops with signing and encryption. A factor slower (10x)
