# Global networks in AWS Global Networks for Transit Gateways
<a name="global-networks"></a>

A global network in AWS Global Networks for Transit Gateways is a container for your network objects. When you create a global network, you create only the framework of the global network itself. You'll then further define this network by adding network objects to it, such as 
+ transit gateways.
+ sites, devices, and links, and then creating connections using links between those sites and devices. 
+ customer gateway associations.
+ Connect peer associations.

**Note**  
When creating a global network, you're prompted to create an associated core network. A core network is a feature of AWS Cloud WAN and is not needed if you're not using this feature. While creating a global network, you're prompted whether or not to create a core network. Clear the option to create the core network. If you decide later on that you want to create a core network for this global network you can. For the steps to create a core network, see [What is AWS Cloud WAN](https://docs.aws.amazon.com/network-manager/latest/cloudwan/what-is-cloudwan.html) in the *AWS Cloud WAN User Guide.* 

You can create, view, update, and delete a global network using either the AWS Network Manager console or by using the CLI.
