Turnkey Linux

Turnkey Linux is a virtual appliance library that integrates and polishes the very best open source software into ready to use solutions. Each virtual appliance is optimized for ease of use and can be deployed in just a few minutes on bare metal, a virtual machine and in the cloud.

We believe everything that can be easy, should be easy.

Packaging a solution as a virtual appliance can be incredibly useful because it allows you to leverage guru integration skills to build ready to use systems (I.e., turn key solutions) that just work out of the box with little to no setup.
