Live disk (Live CD/USB)
In order to simplify maximum the OpenSCADA deployment, you can use live builds of boot-able CD and USB disks. Live disk provides the ability to boot directly from it and quickly to obtain the desired working environment. During booting and operating a live disk does not use regular data storages, which means you can not worry about the integrity and safety of data on them. In general, a live disk is a convinient tool with a wide range of necessary software tools, independent from the stationary software environment, and capable to make diagnostics of software and hardware environment, and their restoration in some cases.
