Around ten years ago the ASP model was being touted as the next great wave of technology. The ASP –Application Service Provider model was trying to do Software as a Service (SaaS), and it didn’t ever really live up to the hype. So here we are ten years later, what has changed? Technology has grown up, and hardware is dramatically more powerful than it was ten years ago. The ASP models simply didn’t scale or make economic sense. We now have improved bandwidth, more powerful hardware, and the “Secret Sauce”-Server Virtualization. Virtualization means we can slice up this hugely powerful hardware into digestible chunks and sell it off whilst still making a profit. The concept of multi-tenancy (more than one company sharing the same tin) was not achievable without Server Virtualization, multi-tenancy is key to the large cloud models.
There is a lot of noise around Cloud - this as a Service, that as a Service even X as a Service (XaaS)! What does this all mean, and how is this so different from existing outsourcing models?
