# About Networks

In order to provision cloud clusters, you must first deploy a network into your cloud account. A network is a networking stack deployed into your cloud service provider (CSP) that clusters run on top of. Networks are managed per cloud account, and you can deploy multiple networks within a single account.

Below, you can find specific details about the implementation of networks for each CSP.

## AWS Networks

Deploying a network provisions the following resources on AWS:

- a Virtual Private Cloud (VPC)
- an internet gateway
- public and private subnets
- public and private route tables and routes
- an Elastic IP address for the NAT gateway
- a Route 53 Hosted Zone
- a security group

The schematic below shows an ACTIVATE-deployed cluster in AWS Cloud.

The controller and compute nodes are shown in Availability Zone us-east-1a inside the us-east-1 Region. When using the default networking mode, compute nodes in a region use a single NAT gateway for outbound internet connectivity. This NAT gateway is pre-provisioned as part of the network. The AMI used for the controller and compute nodes is inside the Parallel Works AWS account.

:::info Expense Information

Depending on the networking mode, a NAT gateway will be created resulting in an additional monthly charge in your AWS account. For more information, please see this [AWS pricing list](https://aws.amazon.com/vpc/pricing/).

## Azure Networks

Deploying a network on Azure provisions a similar set of networking resources, including a virtual network, subnets, NAT gateway, and associated security rules.

## Google Networks

Deploying a network on Google Cloud provisions a VPC network, subnets, firewall rules, and Cloud DNS resources in the specified project and region.

## OpenStack Networks

For OpenStack environments, network configuration is specific to your OpenStack deployment. Networks are created using your provider's available networking resources, regions, and flavors.
