Excuse me please but for me sounds amazing that at this stage architects of the OGSA community are still asking what is a grid and if hdw/sfw, virtual or real, are resources that might be grid components. Olegario Hernandez At 13:28 23/10/2005, Donal K. Fellows wrote:

I've always taken the view that the Grid is an abstraction of all that hardware/software/service gunk. As a consumer of the Grid, you should not care, and should not have to care, whether the thing you are using is real hardware, virtualized, a pure software entity, or what. Just like as a consumer of electricity from the grid, you're not too bothered about whether that power came from burning coal, oil or gas. Abstract virtualization (which is probably not exactly what you're talking about, but an abstraction of it) is almost certainly the real key to it all.
Naturally, those people involved in the management of the Grid will care, but they should be in the minority, just as electric company employees are in the minority compared to power users.
Here's hoping this makes things clearer, not more obscure!
