A virtual or a dedicated server is a standalone machine, that has its own Operating System and keeping the latter up-to-date is an important, albeit underrated task. Not only can an update enhance the overall performance of your internet sites, but it could also save you a great deal of troubles later on. An update could be released for a lot of reasons, the most frequent being to fix recently identified security holes, which may allow third-party people to access and modify the content you have on the server. You can also see an improved efficiency of your web applications because updates may also be released for better compatibility between the Os and the configuration it functions on as a way to get the most out of the hardware. Furthermore, if you keep your programs up-to-date, they may also require a later Operating system version that will have the required software dependencies and will allow them to work adequately.
