Cisco SD-WAN Integration with AWS Transit Gateway Connect Raises the Bar for Cloud Performance and Scale

As the SD-WAN enterprise customers increase their consumption of business-critical applications from cloud or directly as SaaS over the Internet, there is a growing need for on-demand SD-WAN extension to the cloud or SaaS of choice.

Cisco has partnered with AWS, to deliver Cisco SD-WAN Cloud OnRamp to extend our SD-WAN fabric to AWS workloads.

As our customers transition their workloads to AWS, Cisco continues to build on this partnership to accelerate our customer’s SD-WAN journey to AWS.

In our current integrated solution between Cisco SD-WAN and AWS Transit Gateway, Cisco SD-WAN Cloud OnRamp enables users to connect to their AWS workloads using the Cisco SD-WAN controller(vManage). The Cloud OnRamp feature automates Cisco SD-WAN fabric extension from branch routers to Amazon VPCs. In addition, the integration with TGW Network Manager enables seamless network visibility either through vManage or AWS console. This provides a comprehensive view of the on-premises network, including the WAN, and the customer’s AWS network. All underlying tasks such as spinning up Cisco SD-WAN cloud routers, such as Catalyst 8000V Edge Software, creating Transit VPC, and establishing IPsec VPN tunnels to AWS TGW and forming BGP adjacency are completely automated. In addition, customers can extend network segmentation policies from on-premises to AWS Cloud via a simple-to-use GUI in Cloud OnRamp.

The existing solution with Cloud OnRamp automates the entire orchestration of the TGW and VPC networking, hence reducing the time-consuming manual task to a matter of minutes.

We have integrated further with AWS on our current solution, for customers requiring throughputs in excess of the 1.25 Gbps that is possible today with an IPsec tunnel connection, and preferring not to manage establishing multiple tunnels to scale bandwidth beyond 1.25Gbps. While some other customers have security/compliance considerations and need to establish private IP addresses along the entire path from branch to AWS.

In response to our customer requirements, we are excited to announce our latest integration of Cisco SD-WAN Cloud OnRamp with AWS Transit Gateway Connect.

This latest offering with AWS Transit Gateway Connect, builds upon our existing AWS relationship to provide a tightly integrated solution with additional key benefits, like:

1. Reduced costs with higher bandwidth connections: The new integration between Cisco and AWS uses native GRE tunnels instead of IPsec tunnels, offering up to 4 times the bandwidth and eliminating the challenges and costs of establishing and maintaining a multitude of IPsec tunnels.

2. Enhanced security: By removing the need for public IP addresses, customers with strict security requirements can deploy the solution using private IP addresses to significantly reduce the attack surface reducing risk and streamlining compliance.

3. Increased route limit: This new architecture will increase the number of BGP network advertised routes many-fold over the existing 100 route limit. **

4. Increased visibility: Integration with Transit Gateway Network Manager will provide an increased level of visibility such as performance metrics and telemetry data not only from the third-party appliances but also from the branch appliances sitting behind them. This allows customers to monitor end-to-end network across AWS and on-premises.
