# AWS PCS Networking
<a name="working-with_networking"></a>

Your AWS PCS cluster is created in an Amazon VPC. This chapter includes the following topics about networking for your cluster’s scheduler and nodes.

Except for choosing a subnet to launch instances in, you must use EC2 launch templates to configure networking for AWS PCS compute node groups. For more information about launch templates, see [Using Amazon EC2 launch templates with AWS PCS](working-with_launch-templates.md).
