Understand more about DMZ

I want to understand more about DMZ, it plays a vital role in big network. Cloud data storage when connected to LAN vulnerabilities terms of security.

The DMZ is where you place servers/services that need inbound access from the Internet. i.e. The Internet need to access them like a web server. You put them in a DMZ so that you dont need to give direct access into the private LAN. If a DMZ server is compromised the attacker doesn’t have direct access to the private LAN.
