Connect your VPC to other VPCs and networks using a transit gateway
You can connect your virtual private clouds (VPC) and on-premises networks using a transit gateway, which acts as a central hub, routing traffic between VPCs, VPN connections, and Amazon Direct Connect connections.
One of the key benefits of using a transit gateway is the ability to centralize and simplify the management of connectivity between your VPCs and on-premises networks. Rather than configuring multiple VPN connections or Direct Connect links, you can leverage the transit gateway as a single point of integration, which can help reduce the overall complexity and operational overhead of your network architecture.
The pricing for using a transit gateway is based on the volume of data transferred through the gateway. There is a per-GB rate for data transferred in and out of the transit gateway, as well as a separate per-hour rate for the transit gateway resource itself. The specific pricing can vary by Amazon Region and is subject to change, so it's important to refer to the current Amazon Transit Gateway pricing page for the most up-to-date information. By understanding the pricing model for transit gateways, you can better plan and budget for the ongoing costs associated with this Amazon networking service. This, combined with the operational efficiencies and connectivity benefits, makes transit gateways a compelling choice for organizations looking to build scalable and cost-effective hybrid cloud solutions.
The following table describes some common use case for transit gateways and provides links to more information.
Example | Usage |
---|---|
Centralized router | Configure your transit gateway as a centralized router that connects all of your VPCs, Amazon Direct Connect, and Amazon Site-to-Site VPN connections. For more information, see Example: Centralized router in the Amazon Transit Gateway User Guide. |
Isolated VPCs | Configure your transit gateway as multiple isolated routers. This is similar to using multiple transit gateways, but provides more flexibility in cases where the routes and attachments might change. For more information, see Example: Isolated VPCs in the Amazon Transit Gateway User Guide. |
Isolated VPCs with shared services | Configure your transit gateway as multiple isolated routers that use a shared service. This is similar to using multiple transit gateways, but provides more flexibility in cases where the routes and attachments might change. For more information, see Example: Isolated VPCs with shared services in the Amazon Transit Gateway User Guide. |
