With two delivery models in the Cisco IT Elastic Infrastructure Services (CITEIS) program, Cisco IT is meeting the needs of developers who just want raw servers and storage and those who want a fully managed platform service. The two models are an ongoing subscription service for a virtual data center (VDC) and a customizable set of resources for short-term use.
More and more businesses these days are taking steps to reduce their carbon emissions. (Cisco is one of them, as the company met a 25% greenhouse gas reduction goal last year and subsequently upped it to 40%.)
There are several compelling reasons for doing so – some philosophical and others pragmatic. Here are a few:
Saturday morning wasn’t complete for me as a kid if it didn’t include a bowl of pre-sweetened cereal and time watching cartoons.

Hence why it’s a bad idea to compare PUE among Data Centers.

I went shopping for a car last year and was pleased to see several models equipped with real-time displays of their miles per gallon performance. That’s a great feature, in my opinion, because it offers drivers up-to-the-moment insight into how efficiently their cars are operating.
