"Everyone loves a turnkey solution and everyone wants a turnkey
solution. Who wants to use multiple vendors for what a customer
perceives as a single service? Thanks to the coolness of Linux, the
power of Amazon's EC2 services and the entrepreneurial spirit of
Alon Swartz and Liraz Siri, TurnKey Linux delivers turnkey
solutions to bare metal, virtual infrastructure and to Amazon's EC2
environment in the form of virtual appliances. And, TurnKey Linux
is, like its Ubuntu parent and Debian grandparent, free.
"There's also an added bonus with TurnKey Linux: Cloud-based
backup. And, it's inexpensive ($0.15/GB). This cloud-based backup
feature uses the Amazon Simple Storage Service (S3) for unbreakable
backup and restore."
