I already know how to create a Minecraft server and bring it online via port activation. However, it always says: with port activation it is not safe. Now the question of how Gommehd does his server, for example. The answer: "Yes, he bought it through a provider such as nitrado"
does not interest me. Because e.g. Nitrado has to do the server somehow. So how do such providers make servers?
Vendors like Nitrado do nothing but you at home, but on a large scale. They have a huge network there. Unfortunately, you will notice over time that your server is lagging (if you build a lot). You don't have that with such providers.
Hosters have some large servers that run many small ones. V server
They also have some big ones that run on their own. Dedicated server.
Virtualization is very resource-intensive and rarely useful for private individuals
They are protected by firewalls and proxies
Providers who rent out servers themselves very likely have a large cluster in a server center.
