Servers are what make up the physical basis of the internet. Setting up your own professional site, putting products online for sale, or connecting multiple company locations with one another: all of these tasks require the support of high-performance computers. And it doesn’t matter if you purchase hardware resources for your own data center or opt for the flexibility of cloud services: operating a server comes with the challenge of independently configuring and administering hardware components. But don’t worry, there’s a lot of support out there for these tasks. In the Server Guide of IONOS’s Digital Guide series, you’ll find regular articles, news, and tutorials on how to operate this indispensable component of today’s IT infrastructure.
