20 Jul 10 Cloud Computing With Less Security Risk

“My company’s data is much too sensitive to be stored in the cloud.”
That’s probably the most common justification you’ll hear for not considering switching from applications run in the corporate data center to ones managed by a service provider and run in the cloud. The implication is that if you move your data to cloud storage, you will lose control over it and it will therefore be less secure.
Yet the potential benefits of cloud computing are well known — they include
* Lower capital outlays
* Fixed, known monthly costs
* Scalability
* Low management overhead
* Immediate access to technology
It would be wrong to say all organizations should move all their computing tasks to the cloud, but it’s almost certainly the case that many organizations could profit from the benefits described above — if the security risk, real or perceived, could be reduced.
19 Jul 10 Cloud Computing – The Emerging Computing Technology

Cloud Computing, a virtualization and distributed computing technology that combines many server infrastructure delivering a slew of cloud-based services, from full-blown applications to storage services to antivirus services.
According to Berkeley scientists, “Cloud computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS), so we use that term. The datacenter hardware and software is what we will call a Cloud.”
With this cloud computing technology, the local computers no longer have to do all the heavy computing process or data storage. The network of computers / server that make up the cloud handles them instead by centralizing storage, memory, processing and bandwidth provide greater computing capacity and data storage via online without the costs and headaches of owning all the hardware. The only thing the user’s computer needs to be able to run is the cloud computing system’s interface software, which can be as simple as a Web browser, and the cloud’s network takes care of the rest.
Cloud computing are broadly divided into three categories Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).
