Cloud Computing

I have talked about cloud computer in several posts in this blog. I was happy to find a good explanation of what cloud computing is and how it is already a part of our everyday computing world.

Schneider on Security has this to say about cloud computing:

This year’s overhyped IT concept is cloud computing. Also called software as a service (Saas), cloud computing is when you run software over the internet and access it via a browser. The Salesforce.com customer management software is an example of this. So is Google Docs. If you believe the hype, cloud computing is the future.

But, hype aside, cloud computing is nothing new . It’s the modern version of the timesharing model from the 1960s, which was eventually killed by the rise of the personal computer. It’s what Hotmail and Gmail have been doing all these years, and it’s social networking sites, remote backup companies, and remote email filtering companies such as MessageLabs. Any IT outsourcing — network infrastructure, security monitoring, remote hosting — is a form of cloud computing.

The old timesharing model arose because computers were expensive and hard to maintain. Modern computers and networks are drastically cheaper, but they’re still hard to maintain. As networks have become faster, it is again easier to have someone else do the hard work. Computing has become more of a utility; users are more concerned with results than technical details, so the tech fades into the background.

The post ends with a part on how this affects IT security and the need for trust. This is definitely true. Whether it is online banking, online shopping, or even going through emails, people need to trust the security of the online software and applications they use. This is because as Schneider points out that most of what people use the web for is already cloud computing.

  1. You’re right people do need to trust that their data is safe and secure. I believe the new companies coming into the cloud market realize this and are doing everything possible to make the cloud safe. http://www.workxpress.com
