Cloud computing is not a brand new concept, just a new term. It is kind of like running a virtualization system like a thin client. In a thin client / server situation the desktop aka client sends a request to the server to acquire the operating system. All of the processing is done on the server and the output for the user is displayed on the clients screen.

Cloud computing works in my understanding works very much in the same way. In a software as a service environment the application delivers a user interface to the desktop. For example, when a user logs in to a web based email service and wishes to compose a new message they see a rich text editor. This rich text editor is kind of a virtual application. Instead of having to install an email client or office suite on the machine itself, the applications interface is delivered through a web browser, as is the case with web based email service.
Another example I can give is a service I use, dotnetnuke. I have hand coded websites in the past and used wsiwyg editors installed on my computer, which I still do for the most part. My webhosting provider offers installable applications on their hosting packages. I choose dot net nuke for one of my websites just to see what it could do for me. After getting used to the user interface I quickly discovered that I could add content via the built in modules, drag and drop, and even use custom html if I wanted to. The controls are on my browser and the actions take place in a data center elsewhere.

Some other major software companies deliver entire office suites via a browser interface but I never experimented with these services yet. This could be a way for some companies to cut down on overhead within their IT Departments. This could cause a shift in duties for IT Professionals who install application software on end user devices.

In a nutshell; All the end user would require is a terminal to load an OS and a browser. The IT department would require a server to deliver the OS and browser to the terminal. And the server would require a reliable link to the cloud aka internet. I understand why a company would want a private cloud. The processing is done on a server within the LAN and in the event of something going wrong, the admin team could respond quickly. I also see possible security issues with relying on “the cloud” for mission critical applications. But for smaller companies who don’t need their own email server on site this would be a way to go. Also the idea of having an online office suite subscription could save some bucks too.

In computing world, storage and computing resource also can be provided by could computing service.

Do you agree ?

Linksys really needs to come home to reality!! Our last two encounters with the customer service department has been quite unsatisfactory. When talking to the reps, it feels like you are talking to a rock or some being that is totally unable to think, …

First I tried PC Tools, which found some stuff, and thought it was OK, but still had browser and word problems. So I tried Cyberdefender, and it found even more stuff. Afterwards my system worked ok.

I like that it looks for trojans, malware and sypware – not just viruses. I liked it enough, that I paid for the upgrade, cuz I wanted the back-up, and the ability to contact someone at Cyberdefender who will answer any of my (or my family’s) questions.
