Overheard: The future of SaaS is in appliances?

mayank_sharma.jpg Today, virtual appliances are becoming a de-facto means of software distribution and have spawned a new type of business — the virtual appliance vendor.

Along with software vendors and virtualization software companies, appliance vendors are putting in the extra effort to streamline the distros that power the apps. So, for example, Bugzilla, the popular bug tracking app, is available as a 2.4MB download tarball from Mozilla, as well as a 150MB appliance from appliance vendor Jumpbox. Mathematically, this is 62.6 times the size of the app, but in 150MB you’re also getting an operating system, stripped to the bone and optimized to run only that particular app.

Am still trying to figure out why we won’t be using virtual appliances for just about everything and how the distribution model fits in with SaaS.

Overheard: A virtual appliance isn’t something you buy on Second Life

josh_suereth.jpg So what is a virtual appliance? A virtual appliance is a virtual machine that can be distributed (like any file) and deployed onto some hypervisor (a server that runs virtual machines). Because a virtual appliance is an entire virtual machine, the appliance developer has control of the entire aspect of the machine, from operating system to window themes to startup procedures.
