Hi, I have a question. Why is proposed Grid definition on slide 5 doesn't mention anything about virtualisation and dynamics? "What is a Grid System? A Grid system is a collection of distributed resources connected by a network." Yuri Hiro Kishimoto wrote:

Thanks Andrew,

I've moved this file from "background draft" folder to "Meeting Materials and Minutes:Other" folder since I want to keep all such presentation slide decks in single folder.

there is no virtualisation mentioned in this presentation. People in the crowd are a bit confused by some slides :-) especially that there is no continuity of the definitions from the "Anatomy" and "Physiology" of the Grid. I mean virtualisation, dynamics and user-centric security. Yuri

I would argue that what makes a "grid" is the software .. at the same time, hardware is a necessary, but not sufficient condition. People in what crowd? That slide set has been presented exactly once - and there was no crowd :-) We will be discussing it in one of the next few telecon's - I believe.

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!
