Cloud Computing

Cloud ComputingSecurity is one constituent that perhaps shadows the viewpoint for cloud computing more than any other.

The cloud industry is working hard so as to boost security, but corporate computer users still have qualms over it.

That's one of the chief issues holding back acceptance of shared public clouds by companies and by the federal Government, said Jonathan Nguyen-Duy, Director of Security Product Management at Verizon Business, which offers cloud computing services.

Regardless of security issues, a lot of firms are shifting to cloud computing in a bid to save cash and make it simpler to expand or contract as required.

In cloud computing, users' applications and data are stored in data centers and delivered when demanded by means of the Internet, or the cloud.

Some firms use this idea, which is also known as on-demand computing, so as to create their own private clouds, essentially virtualized computing centers that the firms themselves control.

Other corporations go with outside suppliers, by making use of the public cloud.

Even private clouds needs added security, says Christofer Hoff, Director of cloud and virtualization solutions at Cisco Systems (CSCO).

But in a public cloud, the problems are a little more appealing, he said, since customers have to depend upon the security that is offered by the public cloud providers.
