How Cloud Computing Works

Let's say you're an executive at a large corporation. Your particular responsibilities include making sure that all of your employees have the right hardware and software they need to do their jobs. Buying computers for everyone isn't enough -- you also have to purchase software or software licenses to give employees the tools they require.

What cloud computing really means

Cloud computing is all the rage. "It's become the phrase du jour," says Gartner senior analyst Ben Pring, echoing many of his peers. The problem is that (as with Web 2.0) everyone seems to have a different definition.

SDN Market To Surge As Cloud Computing Grows, Research Firm Says

The software-defined networking (SDN) market will grow sixfold during the next five years, fueled by cloud computing, according to the Dell’Oro Group.

According to the firm's Data Center Disruptors Advanced Research Report, the majority of this market will be composed of Ethernet switches and network security appliances, which are projected to represent 75% of total sales revenue in 2013.

"But the surge [in] cloud deployments is causing the overall data center portion of the Ethernet switch market to grow. It is likely that SDNs biggest impact over the next several years will occur in the cloud -- both public and private -- and not in traditional enterprise data centers." Read more.
