New "grid" website goes live
One of the competing visions for enterprise application integration is the notion of "grid" technology, which as a term has about as precise a definition as "Service-Oriented architecture". Recently Oracle and Ziff-Davis launched a new website geared towards grid computing, and it's worth a look if only to understand what a "grid" is.
In many respects, "grid" is the Holy Grail of distributed systems, and the ultimate expression of clustered servers: "The Grid unites servers and storage into a single system that acts as a single computer - all your applications tap into all your computing power. Hardware resources are fully utilized and spikes in demand are met with ease.", according to the Website's Introduction. There's an intrinsic bias towards using Java for grid computing (understandable given Oracle's current technology focus on Java), but it raises the interesting question, are grids a useful concept, and if so, is there anything stopping a company from building a .NET grid? Particularly if, as IBM seems to believe, the grid should be built using Web service specifications?

the only problem I see is cultural. those who build grids and have several years of hardcore experiece prefer an open ecosystem. In the grid communities that i can see, likd globus, there doesn't seem to be a lot of love for Microsoft. Though I believe globus does provide a windows client.

Grid Computer vs. Load Balanced Server Farm?
Is there a major difference between this? Is one easier/more cost effective to set up and maintain? Are there significant performance changes between grids and farms? Are they even comparable, or am I talking apples and oranges here?

Grid Computer vs. Load Balanced Server Farm?
Is there a major difference between this? Is one easier/more cost effective to set up and maintain? Are there significant performance changes between grids and farms? Are they even comparable, or am I talking apples and oranges here? there are many diffinitions of grids and clusters, but there is an important difference. my own definition is this. A cluster of servers in a load balancing configuration is not a grid, because a grid makes a cluster of system appear as one system. this is an important distinction.
for example, a cluster of webservers behind a local director is not a grid. each webserver handles a single request at time and a single process is not distributed across multiple systems. A simple example of a grid would be something like distributed indexes like http://www.jxta.org/, the peer-to-peer network. The jxta network manages the distribution of search indexes to reduce the time to query and return results. by intelligently distributing indexes and queries, the network optimizes the routing of data. a farm of webservers typically do not work in this fashion. this is a fascinating topic and there are hundreds of articles. hopefully my bastardized explanation isn't too gross.
