That IP will be the Virtual Private Server (VPS) IP address. Instead, we can have a domain name registered and pointed to the VPS. The second and better way is to hide it behind a proxy server.

Load balancing is the process of distributing loads among similar servers. We saw what types of loading mechanisms are available. Some of them are Round Robin, IP Hash, Least Connection, and so on. Then, we added authentication...
