Oracle Virtual Compute Appliance Webcast on April 16

You may have heard of the Oracle Virtual Compute Appliance, an Oracle Engineered system for running virtual machines using Oracle VM. I've been working a lot with this product over the past several months, so I'm overdue to blog about it. It's really a powerful platform with built-in compute, network, and storage resources - something often referred to as "converged infrastructure". What makes it most powerful, in my opinion, is that the environment is automatically discovered and configured when you power it up, so you can create and run your virtual machines right away and without having to go through laborious design and planning.

Today I want to point you to an upcoming webcast to be held April 16. The webcast will highlight an update to the product, and you can register for it at I can't give advance information on what's to be announced (that would spoil the surprise), so please register for the event.
