After a technology has been introduced, the market has become disillusioned by it, and then good technologies begin to rebound in popularity, or what Gartner calls a "slope of enlightenment," Gartner says. These are technologies that are market-proven and are entering beyond the hype phase and into the mainstream.

SaaS: Gartner predicts that for the first time, more than half of organizations are using some form of SaaS, which has moved the technology beyond the peak of hype and toward mainstream adoption. But the SaaS market is broad in and of itself, and Gartner notes that while it is proven in some markets, it "remains nascent in complex applications markets, such as ERP." The process of having an application be owned, delivered and managed by a provider, the report says, can create efficiencies for an organization, especially smaller businesses that do not have an IT shop to support application maintenance or the accompanying infrastructure. But, while SaaS may create a savings in the first two years of a deployment because it removes the need for capital expenses, the operational expenses can remain the same, diminishing the net impact of SaaS after a few years.

: Virtualization is the process of abstracting an IT resource for its physical hardware, which can be done in a variety of areas, including in compute servers, storage and network. Virtualized servers, which create virtualized machines, are becoming ubiquitous in the market, Gartner says, with more than half of x86 servers being virtualized, a number that Gartner predicts will grow to three-quarters by 2015. Storage virtualization, meanwhile, is similarly advanced but not as widely adopted. Because of the level of adoption of virtualization technologies, Gartner says the technology is past its hype and being adopted in the mainstream.

There are a bevy of technologies that are emerging as the need for them increases. There is a technology trigger for these technologies, but there has not been a hype around the term ... yet.
