AWS hybrid connectivity building blocks

From the hybrid connectivity architecture point of view, there are three primary components that construct the building blocks of a hybrid network connectivity architecture:

AWS hybrid connectivity services – these services represent the abstraction layer of the AWS Cloud networking components. They handle the connectivity and routing to the customer infrastructure in AWS and are running on highly scalable and reliable AWS infrastructure.

Hybrid network connection – this component refers to the connection from the on-premises networking edge device to the AWS Cloud (it can be physical connection such as AWS Direct Connect, or an overlay connection such as a Site-to-Site (S2S) VPN)

On-premises customer gateway device (CGW) – this networking device must meet AWS technical requirements and perform IP routing and forwarding.


For connections to Direct Connect with port speeds of 1 Gbps or higher, your customer gateway device needs to meet the requirements listed under the Prerequisites section of the Direct Connect user guide.


For Site-to-Site VPN, the customer gateway device can be a physical or software appliance. For more information about tested network devices by AWS, see Your customer gateway device in the Site-to-Site VPN User guide.

Because this whitepaper focuses on the selection and design of the hybrid connectivity, the following topics provide a brief definition of each of the connectivity types with a link to the respective documentation for further details. We recommend that you have a good understanding of the content covered in the AWS whitepaper, Amazon Virtual Private Cloud Connectivity Options.
