February 06, 2013, 3:57 PM — Startup Ravello Systems launched a hypervisor this week that sits on top of other hypervisors.
A perceived nirvana of cloud computing is being able to take an application that's running on your premise and spin it up in the cloud, without making any changes to the code. Ravello says it can do that with its application hypervisor, which sits on top of virtual machines to allow portability of apps and VM images. Basically, Ravello is virtualizing virtualization.
Company executives have extensive experience: The three top execs served as vice president of engineering, vice president of business development and manager of the virtualization business line at Red Hat. Ravello has received hefty backing too, with $26 million of funding committed from Sequoia Capital, Norwest Venture Partners and Bessemer Venture Partners.

Navin Thadani, senior vice president of products for Ravello, says enterprises are not able to effectively use the cloud today. If a developer wants to spin up an app they've built on site in the public cloud, too often it requires significant changes to the code. "The cloud has all different VMs, different networking from their own data centers," he explains. That doesn't allow for easy migration to the cloud.
Ravello's software analyzes the application and "normalizes" it so that it is abstracted from the virtual machine it's running on. The application hypervisor, named HVX, in essence records the qualities of the apps and recreates them in a new environment with all the same qualities and attributes. Virtualizing the application by abstracting it from the underlying VM it's running on allows the app to be more portable. The app will not know the difference whether it's running on a VMware hypervisor or an open source KVM. "Unlike other hypervisors, this wasn't designed to run on a physical x86 server, it was designed specifically to run in another VM," Thadani says.
Ravello has a drag-and-drop graphic user interface (GUI) that allows customers to deploy their app to public clouds from Amazon, Rackspace and HP. Once the app is running in the cloud, developers can clone the app to test out changes without them being launched in production. The developer can bring the app back in-house using the same process.
