Here’s a great article on GigaOM about getting out of the data center business.
For operationally minded folk (e.g. first responders, emergency managers, security professionals, and military) this article provides a good briefing on the factors at play in making “the cloud” a reality for you. If you can’t get onto a public cloud then you need to work with your partners to establish a private cloud – otherwise you won’t be able to benefit from rapidly dropping costs (both capital and operating).
For a higher-level briefing on the cloud I have a YouTube video about “The Cloud for Senior Leaders” that may help here too.
