How do VPS services
Imagine you have a toy box (VPS) that can be used as a computer for the internet. There’s a special rule: only one box can have one open door (port 80) so everyone can see what’s inside. You have just one public address, but you can only open one door at a time. That’s why you can’t have many websites using the same port at once.
It’s possible through careful configuration and load balancing. Multiple services can run on a single port by distributing traffic across several VPSs or servers. Each VPS handles its own service, and a router or load balancer directs requests to the appropriate instance. This setup allows you to share a public IP while maintaining performance and reliability for each service.
The reverse proxy handles requests by routing them based on the domain provided. When a connection attempt comes in with a specific domain like mc1.yourdomain, it directs traffic to a designated host such as port X. Similarly, for mc2.yourdomain, it sends the request to port Y. Your servers must be set up to operate on these ports internally.
The concept of Virtual Host involves hosting multiple websites on one server. Each site can have its own IP address or share the same IP with different names. This setup hides the fact that several sites operate together on a single machine. Apache initially offered IP-based virtual hosts, and later versions added support for name-based ones, which are also known as host-based or non-IP virtual hosts.

Additionally, some applications such as Minecraft utilize SRV DNS entries. These records provide the client with an IP address or hostname along with a specific port number. This enhances usability by presenting information in a more user-friendly format. Learn more about this feature.
I might configure two virtual machines, each with Postfix and Dovecot, for separate domains. Since web hosting usually provides an email address, I’d need to set that up separately. Because SMTP and IMAP aren’t accessible over HTTP, I wouldn’t be able to proxy them using Apache or Nginx.
It doesn't matter if it's not http. This guide shows how to use nginx to forward SSH, FTP, SQL and more: https://www.howtoforge.com/reverse-proxy...ing-nginx/ Hosting your own mail server is going to be a challenge, especially because most self-managed origins risk getting blocked for spam reasons. I used to run my email 10 years ago, but now when I manage other services it's the one I pay for yearly—hosted by the same provider as my domain.
