A virtual or a dedicated hosting server is a standalone machine, which has its own Operating System and keeping the latter up-to-date is a vital, although underestimated task. Not only can an update boost the overall performance of your websites, but it will also save you a great deal of troubles later on. An update can be released for a number of reasons, the most frequent being to fix recently identified security holes, which may enable third-party people to access and alter the content which you have on the hosting machine. You can also see an improved overall performance of your web programs since updates may also be released for better compatibility between the Operating System and the configuration it works on in order to get the most out of the hardware. In addition, if you keep your programs up-to-date, they might also require a later Operating system version which will have the needed software dependencies and will allow them to function effectively.
