ElasticDrive is a Distributed Remote Storage System. It provides the ability for a remote storage resource such as Amazon’s Simple Storage Service (S3) to look like a local device in Linux, allowing a cheap and safe real-time mirror to be constructed. ElasticDrive allows for an instant snapshot of any logical volume for the purpose of backing up of data in a consistent state without compromising availability. This provides access to a file system as it appeared at any point in time with the ability to easily roll back, migrate or access from any web connected device. Distributed transactional caching maintains consistent access to the file system across any number of physical and virtual server environments. Virtualization solutions enhanced by Intel VT allow a platform to run multiple operating systems and applications as independent virtual machines. Using virtualization capabilities, one computer system can function as multiple

Introduction to Open Virtual Format

Enomalism uses an open Transport format called Open Virtual Format (OVF) for a Virtual Appliance a collection of virtual machines that together provide a single useful facility.

OVF is a packaging format for software appliances. Once installed, an OVF adds a self-contained, self- consistent, complete software solution. An OVF may contain a fully-functional and tested web-server / database / OS combination, such as a LAMP stack (Linux + Apache + MySQL + PHP), or it may contain a virus checker, including its update software, spyware detector, etc.

From a technical point of view, an OVF is a transport mechanism for virtual machine templates. One OVF may contain a single VM, or many VMs (it is left to the software appliance developer to decide which arrangement best suits their application).

As a transport mechanism, OVF differs from VMware's Virtual Disk Format and Microsoft's Virtual Hard Disk format. Both of those are run-time VM image formats, operating at the scope of a single VM disk, and though they are being used as a transport mechanism, they are not designed to solve that problem; they don't help you if you have a VM with multiple disks, or multiple VMs, or need customization at install time, et cetera. Included within the OVF remit is the certification of delivered software, allowing the platform to determine the provenance of a given appliance, and to allow the end-user to make the appropriate trust decisions.
