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, although underrated task. Not simply can an update boost the general performance of your sites, but it can also save you a great deal of issues down the road. An update could be released for several reasons, the most widespread being to fix newly found security holes, which may allow third-party people to access and alter the content that you have on the hosting server. You can also see an improved functionality of your web apps because updates may also be released for better compatibility between the Os and the configuration it operates on in order to get the most out of the hardware. Furthermore, if you keep your apps up-to-date, they could also need a later Operating system version that will have the needed software dependencies and will allow them to work adequately.
