A virtual or a dedicated hosting machine is a standalone machine, that has its own Operating System and maintaining the latter up-to-date is a crucial, though underestimated task. Not simply can an update boost the performance of your internet sites, but it can also save you lots of problems in the future. An update may be released for a number of reasons, the most widespread being to fix recently found security holes, which may permit third-party individuals to access and change the content which you have on the hosting machine. You can also see an improved functionality of your web apps because updates can also be released for better compatibility between the Operating System and the configuration it operates on so as to get the most out of the hardware. Furthermore, if you keep your apps up-to-date, they might need a later OS version that will have the needed software dependencies and will permit them to function properly.
