A virtual or a dedicated hosting machine is a standalone machine, which has its own Os and keeping the latter up-to-date is an essential, although underrated task. Not simply can an update enhance the overall performance of your sites, but it will also save you lots of problems later on. An update could be released for a lot of reasons, the most frequent being to fix newly identified security holes, which may enable third-party individuals to access and modify the content that you have on the hosting server. You might also see an improved overall performance of your web applications because updates may also be released for better compatibility between the Operating System and the configuration it functions on so as to get the most out of the hardware. In addition, if you keep your applications up-to-date, they could also require a later OS version which will have the needed software dependencies and will allow them to function adequately.
