# Transit Gateway Attachments

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

AWS Transit Gateway acts as a cloud router in AWS, simplifying network access between private
spaces, on-premises data centers, and third-party software, while providing increased visibility and
control over the network. Transit gateways effectively merge your organization’s cloud resources and
on-premises datacenters into one network topology.

On CloudHub 2.0, you can take advantage of this network simplification by securely attaching your
private space to AWS Transit Gateway in your AWS account.

You can add multiple transit gateways to your Anypoint Platform organization. The number of transit
gateways you can add depends on the network connection entitlements available to your account.
Contact your MuleSoft account representative if you don’t know how many entitlements are associated
with your account.

To use transit gateway attachments, your private space and AWS Transit Gateway must be in the same
region.

To attach your private space to your transit gateway, see
[Create a Connection to an External Network](https://docs.mulesoft.com/cloudhub-2/ps-create-configure#create-connection-to-external-network).

## Limitations

The following limits are governed by AWS limits:

- Maximum number of transit gateways per VPC

- Maximum number of VPCs that you can attach to a transit gateway

For information about limitations when attaching a VPC to a transit gateway, see
[Transit gateway attachments to a VPC](https://docs.aws.amazon.com/vpc/latest/tgw/tgw-vpc-attachments.html)
