Support for any of these operating systems typically depends on the level of management offered with a particular dedicated server plan. Operating system support may include updates to the core system in order to acquire the latest security fixes, patches, and system-wide vulnerability resolutions. Updates to core operating systems include kernel upgrades, service packs, application updates, and security patches that keep the server secure and safe. Operating system updates and support relieves the burden of server management from the dedicated server owner.
The preinstalled mail server by IONOS is usually enough for beginners and private users to get started immediately. Anyone needing more options can install open source software like PostFix to set up their own mail server. They will need a Linux operating system and root permissions for the server. But that’s no problem, as the IONOS VPS runs on both Windows and Linux operating systems and allows the necessary root access.
Additionally, you'll want a web hosting service that offers Secure Sockets Layer (SSL) if you plan to sell products. Here's why: An SSL connection encrypts the data that travels between your site and users' web browsers, thus safeguarding the transmission of purchasing information. You've probably seen a green padlock in your web browser's address bar while logging into your online bank account or making online purchases. It's a symbol of trust. Some companies include a free SSL certificate when you sign up for a hosting plan, while others charge close to $100. You can save some money by shopping around for the services that offer the cheapest SSL plans.
The answer to this question largely depends on two factors. Are you new to server technology and not very interested? In this case, Windows is the easiest option to get where you want to go. Do you already have experience with Linux or would you like to familiarize yourself with this operating system? If so, Linux gives you more freedoms to configure your server, and you will be using an operating system that is less vulnerable to attacks from the Internet. Linux is also open source and therefore free.
