.NET Grid Computing
Here is a link to an article titled "Scaling SOA with Distributed Computing", describing one reason why grid computing is "hot":http://ddj.com/dept/webservices/193104809
A compute grid allows a single application to run on a network of machines and enables significant improvement in application scalability and performance.An open source project for .NET grid computing is Alchemi (http://www.alchemi.net/) and a commercial .NET grid computing solution is the Digipede Network (http://www.digipede.net).
A free Digipede Network Developer’s Edition can be requested here:http://www.digipede.net/products/dev-edition.html.The Digipede Framework SDK allows a developer to define either a .NET object or a COM Server (using OO methodologies) for distribution, instead of requiring the creation of distributable executables which is how traditional grid computing solutions work.
