Cloud computing is getting all the attention these days in technology journals and publications. Major corporations are shifting from in-house data center operations to cloud computing models for two reasons: better computing for less cost. To understand cloud computing,and why it is suddenly the hottest trend out there, we need to review the context of the evolution of professional computing during the last two decades or so. In the mid-1980s, in the middle of the PC revolution that was shaking the foundation of mainframe computing, Sun Microsystems was growing rapidly, selling expensive servers running Open Source operating system software. Today, when we take for granted the huge network called the Internet, it’s difficult to imagine a time when computers were not networked together, except in limited “Local AreaNetwoks” (LANs)
.During that time, Scott McNealy, then-president of Sun, said, “The network is the computer,” with prescient insight that was typical of him.
Then and Now
Then, every organization had to be self-sufficient for computing—everyone needed their own processor and storage, and connecting computing equipment was complex and expensive. Now, thanks to the Internet, computers can be connected easily and inexpensively. This means that one computer, running on the Internet (the”cloud”), can serve many different organizations. Now software programs, which used to be needed for each organization who licensed it, could be provided for multiple organizations. One set of programming being used by multiple customers, running on one server. The benefits of cloud computing are apparent. More computing capacity for less expense. Now, large organizations are taking advantage of the cloud model;and at Blazing Systems we have designed our delivery model to do the same. The result is that our customers–individual professionals, small-medium businesses, and non-profit organizations, can all gain the same advantages from cloud computing as the large corporations are.We are Open Source, and we endorse the delivery of software as a service(SaaS), not a proprietary product.
