EcommerceTimes is an online publication for small business technology. They published a piece by Jim Damoulakis is CTO at GlassHouse Technologies which is pretty basic. It is a very simple overview, and interesting if you want to see how cloud computing is being marketed to small business.
2009 has turned out to be the breakthrough year for cloud computing — and, just as with the Internet, vendors and consumers are grappling with what it means to them. Vendors seek to tap into a huge market opportunity and are busily developing new products or, at a minimum, repositioning old ones. Users are, by and large, intrigued by the notion of cloud computing and are at various stages of sorting through product offerings and spin in an attempt to identify what aspects of the cloud may prove to be beneficial to them.
