A virtual or a dedicated hosting machine is a standalone machine, that has its own Os and always keeping the latter up-to-date is a vital, albeit underrated task. Not simply can an update boost the performance of your internet sites, but it could also save you a lot of troubles later on. An update may be released for several reasons, the most widespread being to fix recently found security holes, which may enable third-party people to access and modify the content which you have on the hosting server. You might also see an improved performance of your web programs since updates might also be released for better compatibility between the Operating System and the configuration it works on as a way to get the most out of the hardware. Also, if you keep your applications up-to-date, they may need a later Operating system version which will have the necessary software dependencies and will permit them to operate properly.
