[ Cloud Computing ] Re: Do EC2 and others really offer grid computing?

EC2 provides building blocks but you really need something like RightScale on top of EC2 to achieve an operating grid.

Folks,

 

I am new to this group but am reasonably familiar with cloud computing. This weekend, I will be setting my account on Amazon EC2.

 

Among other things, cloud computing incorporates grid computing. What I am trying to understand is how EC2 and other infrastructure providers are actually implementing grid computing.

 

When an application running on EC2 requires requires more computing power, possibly beyond what one physical CPU can ever handle, how exactly EC2 provides this additional power?

 

The infrastructure platform has to take the binary code of the application, analyze it and intelligently distribute it across various physical CPUs. This may be possible for some simple cases. However, for most cases, this is practically impossible.

 

Today's OSes cannot even automatically break an application across multiple threads.All they do is provide APIs for application developers to handle multi-threading.

 

Perhaps the infrastructure platform provides similar APIs to break our work across multiple logical CPUs.

 

Appreciate your insight.

 

Pradeep
