A virtual or a dedicated server 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 functionality of your internet sites, but it could also save you a lot of issues down the road. An update can be released for a number of reasons, the most common being to fix newly discovered security holes, which may permit third-party people to access and alter the content that you have on the hosting server. You might also see an improved performance of your web apps because updates can 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. Additionally, if you keep your apps up-to-date, they might need a later Operating system version that will have the needed software dependencies and will allow them to operate effectively.
