A virtual or a dedicated hosting machine is a standalone machine, that has its own Operating System and always keeping the latter up-to-date is an important, though underrated task. Not only can an update boost the overall performance of your websites, but it will also save you a lot of troubles down the road. An update can be released for a lot of reasons, the most common being to fix recently discovered security holes, which may allow third-party individuals to access and modify the content that you have on the hosting server. You might also see an improved performance of your web applications as updates may also be released for better compatibility between the Os and the configuration it functions on so that you can get the most out of the hardware. Furthermore, if you keep your programs up-to-date, they could need a later OS version that will have the required software dependencies and will allow them to function effectively.
