A virtual or a dedicated hosting server is a standalone machine, that has its own Os and keeping the latter up-to-date is a crucial, though underestimated task. Not only can an update enhance the performance of your internet sites, but it can also save you a great deal of troubles down the road. An update may be released for a lot of reasons, the most common being to fix newly identified security holes, which may enable third-party people to access and modify the content which you have on the server. You may also see an improved overall performance of your web programs since updates might 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. Also, if you keep your apps up-to-date, they may also require a later Operating system version that will have the required software dependencies and will enable them to work adequately.
