A virtual or a dedicated server is a standalone machine, that has its own Os and keeping the latter up-to-date is an important, though underrated task. Not only can an update enhance the general performance of your sites, but it could also save you a lot of issues in the future. An update can be released for a variety of reasons, the most prevalent being to fix recently identified security holes, which may allow third-party people to access and modify the content that you have on the server. You can also see an improved performance of your web apps as updates might 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. Additionally, if you keep your applications up-to-date, they might also require a later Operating system version which will have the necessary software dependencies and will enable them to work adequately.
