In my white paper on IT energy efficiency , I wrote about the need for software developers to design their applications to dynamically scale, so we aren’t simply trading idle servers for idle VMs when applications move to public or private clouds...

[It’s been a long while since my last post – it’s good to be back!] I replaced some alkaline batteries in my son's "activity seat" the other day. As am I allergic to waste, I habitually test the batteries I replace to see if they really are dead. As...

My colleague Matt Robben from the Windows Server performance team has produced a very comprehensive white paper and accompanying blog post which goes into great detail about how you can save energy with Windows Server 2008 power management, including...
