Platform As A Service, or PaaS is the latest development in virtualization. Where companies started to offer applications online (Saas, Software As A Service) and the use of virtual servers is becoming mainstream, more and more companies now offer a complete operating system as a service online.
Cloudo is the latest addition to platform providers. There are several others that have existed for a while now in the consumer market, but to be honest I have no idea if there is a consumer market for this technology. Virtualization is huge in the business market - after offering servers with virtual servers on top even SUN Microsystems now considers offering online platforms for businesses.

So what is so interesting about Cloudo? Why would we want a webbased operating system? Well, something that makes a huge difference is the option to sync your files to the operating system. Until now, nobody else offers this.

There currently is a private beta for developers only, so there's nothing for me there right now. But I will keep an eye on it.

Cloudo is here.
