What’s With All The Linux, I Thought We Were Talking About The Cloud

Our definition is simpler than the NIST definition but, I believe, captures its essence. We assert that cloud computing is characterized by: Transparent scalability On-demand provisioning of IT resources (both hardware and software) A […]
