AWS Networking

Classic network topology Typically, in a classical infrastructure, network architects design multiple networks according to the security wanted for the elements residing in the network. For instance, for a web infrastructure, you could have a front network, where the webservers live, which is accessible from the Internet on ports 80 and 443 ; and a back network, for the database servers, which is only accessible from the front network. This is a fine design, because it allows you to manage security between the networks with firewalls and routing restrictions.
