New "VMcasting" specification formed to drive adoption of automatic virtual machine deployment specifications

Toronto, Ontario. Leading Virtualization and Virtual Appliance Virtualization vendors, Enomaly Inc, virtualappliances.net, and JumpBox announced the creation of the VMcasting specification at www.vmcasting.org.

VMcasting is an automatic virtual machine deployment mechanism based on RSS2.0 whereby virtual machine images (also known as virtual appliances) are transferred from a server to a client, securely delivering files containing a technical specification and virtual disk image format Extensible Virtual Machine (XVM). VMcasting together with virtual appliance formats such as XVMs eliminate the need to separately install, configure and manage interdependencies between virtualized operating systems and applications. Rather then updating single virtual machines, large groups of virtual machines can be delivered at once using a standard definition and process.

"VMCasting for automating delivery and updates of Virtual Appliances snaps in perfectly with delivering instant infrastructure and applications." says Stephen Dennis, president of VirtualAppliances.net, "Smart re-use of existing RSS technology model combined with the delivery encapsulation of XVM will make it easy to implement and use."

The concept of VMcasting is based on the similar concept of Podcasting, the popular trend of audio content delivered via an RSS feed presenting a downloadable or streaming file (often an MP3). With VMcasting, a developer publishes a secure RSS 2.0 feed where each item describes a release of a particular Virtual Machine Image or Virtual Appliance. The items descriptions may contain release notes or other information about what's new in a particular release. Therefore developers can easily be informed of upgraded versions using a virtual server management system such as the The Enomalism Virtualized Management Dashboard (see www.enomalism.com).

Vmcasting is perfectly suited to a variety of virtual machine package formats allowing for a standard mechanism for delivery of virtual appliances. Formats include Open Virtual Appliance (XVM), Amazon's EC2 (AMI), Xen, Vmware, Parallels, Windows Virtual Server (VHD), and Qemu (Qcow).

According to Reuven Cohen, Chief Technologist at Enomaly Inc, "Virtualization technology and in particular virtual software appliances are quickly changing the way enterprise software is deployed. By creating a pre-installed and pre-configured application and operating system environment, system administrators, programmers and IT support staff are able to more efficiently deploy software." Reuven goes on to say "Using VMcasting, system administrators can quickly and easily define parameters and policies for updating a heterogeneous virtual server environment using a standard specification and methodology."

VMcasting was developed to create an industry-standard specification as a secure & uniform definition for the deployment and management of virtual machines (or appliances), independent of any one vendor's virtual infrastructure product suite.
