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 an essential, although underrated task. Not simply can an update improve the overall performance of your internet sites, but it could also save you a great deal of problems 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 allow 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 applications because updates may also be released for better compatibility between the Os and the configuration it functions on in order to get the most out of the hardware. Furthermore, if you keep your programs up-to-date, they could need a later Operating system version that will have the needed software dependencies and will permit them to operate adequately.
