In the early days of enterprise software, it was the automation that fueled the growth of enterprise applications. The vendors that eventually managed to stay in business and got bigger were/are the ones that expanded their footprint to automate more business processes in more industries. The idea behind the killerness of some of these applications was merely the existence and some what maturity of business processes in alternate forms.

According to a Federal Computer Week article by Frank Konkel, The Department of Veterans Affairs terminated its five-year, $36 million cloud computing contract for email and calendaring services with HP Enterprise Services.

Tibbits was not discussing this project in particular, but rather stressing the broader ...

This soon to be released work artfully balances both the technical and business aspects of cloud computing in an easy to read tutorial. Writing from a knowledgeable viewpoint as a blogger at CloudBestPractices.net , Andrea minimizes the normally steep learning curve of applying this new approach for provisioning and consuming information technology. She skillfully  uses humor and easily understood anecdotes to illustrate how businesses can really gain true value. "This book was written for one purpose.   Much like the old Tinder Stratus blog , this book was wri...
