No, as a customer you do not need any knowledge of the operating system of your server, which is a complex, closed system that you do not have direct access to. Instead, we will do all the required technical and administrative maintenance, security, backup and updating work for you, so the full scope and functionality of your IONOS web hosting package is always available to you. All other relevant work, like integrating your content, installing subdomains or creating email addresses can be done easily via a special management interface, without having to work directly with the operating system.
