## Isolated Network
The basic building block of the Atlas Cloud is the Isolated network. It's easy to think of it as analogous to a simple flat home network. The Isolated network is an excellent entry point into the Atlas cloud as it gives you a simple way to start building smaller cloud services. For larger deployments you may want to consider using [[VPC]] networks instead to have better segregation and finer control over your infrastructure.
When you commission an Isolated network by clicking the "Add Network" button you get a simple network with a NAT gateway attached to it.
After creating an Isolated Network you can click your network to configure it. The network should have a public IP address attached to it that acts as the NAT gateway. You can configure egress rules under the "Egress rules" tab.

The isolated network also creates a Virtual Router that handles DHCP in the network.
See [[Public IP Addresses]] for information on how to configure the Firewall and port forwarding.
