After you wade through the confusion that vendors have created, you'll find there are advantages to both public and private cloud offerings. By Tony Asaro I recently conducted a seminar in Seattle for a number of IT professionals and when I mentioned the "cloud" there was a wave of negative reaction. They hated the term and thought that it was just a lot of hyperbole. When our industry latches onto buzzwords like "cloud" and gives them so much airplay, there's invariably a backlash from the user community. It creates confusion and often winds up being counterproductive to vendors' marketing efforts. Adding to the confusion is that more than one type of IT cloud exists. There are application clouds, like SalesForce.com and Google Apps. These online applications are often referred to as software as a service (SaaS), but the "application cloud" moniker is beginning to stick. According to research firm IDC, application clouds already represent an $8.5 billion market, which impacts on-premises IT infrastructures. Applications that ...

Data reduction technologies like data deduplication and compression have been well integrated into backup systems with impressive results. Now those benefits are available for primary storage data systems.
A single director-class switch can replace multiple smaller switches while offering growth flexibility, high availability and a bevy of advanced features.
At one time, storage resource management (SRM) applications tried to be all things for all storage shops, with little success. Modern data storage environments require new tools to navigate the intricacies of virtualized environments, but the jury's still out on whether storage management vendors can meet those needs.
Tape no longer holds the place it once did in most firms' backup environments, but most storage shops still rely on it to some degree. Our Snapshot survey finds that while the vast majority of respondents use disk in backup, nearly 40% plan to buy tape gear this year.

Storage managers want to use their storage systems more efficiently and vendors are finally forking over the tools to do it; but there may be a catch as vendors are faced with decreasing disk sales.
ESG's 2010 Data Protection Survey shows that the trend away from tape continues, with the economics of both deduplication, for disk-based backup, and cloud storage, for long-term retention, contributing to tape's decline.
