A virtual appliance is a copy of an operating system and a set of applications (e.g. OpenEMR), installed, configured, and packaged together into a single download. The virtual appliance runs inside a virtual machine. The virtual machine makes each virtual appliance think it is running on it's own computer. Some of the advantages are:
- snapshots - you can easily save the entire state of the OS and applications as many times as you want
- hardware portability - your virtual appliance can be easily moved to another computer, no worrying about drivers or having the same hardware
- running multiple OSs at once - run linux and windows at the same time without having to reboot
- isolation - keep problems in one OS or applications from affecting others
- easy remote control - you can start, stop, or reset virtual machines remotely
- OpenEMR Virtual Appliances can be run on any Operating System that supports VMware Player or VirtualBox.
- Did I mention yet that VMware Player and VirtualBox are FREE.
