A virtual or a dedicated hosting machine is a standalone machine, which has its own Os and keeping the latter up-to-date is a vital, though underrated task. Not only can an update boost the general performance of your websites, but it can also save you a great deal of troubles later on. An update could be released for many different reasons, the most frequent being to fix recently discovered security holes, which may enable third-party individuals to access and modify the content which you have on the server. You will also see an improved performance of your web applications because updates might also be released for better compatibility between the Os and the configuration it operates on so as to get the most out of the hardware. Moreover, if you keep your apps up-to-date, they could also need a later OS version which will have the necessary software dependencies and will permit them to operate effectively.
