Publication date: **April 25, 2023 ([Diagram history](#sat-high-history))**

With this architecture, you can achieve high resiliency for satellite operator workloads. The solution uses one connection terminating at multiple locations through an AWS Direct Connect Service Delivery Partner with redundant satellite infrastructure.

The following steps describe the data flow and connectivity setup for this architecture:

1. Use satellite communications from your on-premises locations to communicate back to your AWS Cloud environment. Use one customer router and one satellite antenna in multiple locations.

1. Work with an [AWS Direct Connect Service Delivery Partner](https://aws.amazon.com/directconnect/partners/) that provides redundant satellite infrastructure.

1. The partner provides teleport connectivity with one physical connection on two different devices at multiple locations and handles necessary demodulation of your data.

1. The partner sets up one physical connection on different devices at multiple sites. Use these connections for dedicated or hosted connectivity.

1. Order dedicated connectivity or hosted connectivity from the AWS Direct Connect Service Delivery Partner.

1. (Optional) Enable MAC Security.

1. (Optional) Provision private virtual interfaces (VIFs) to access your private AWS resources through [Direct Connect Gateway](https://docs.aws.amazon.com/directconnect/latest/UserGuide/direct-connect-gateways-intro.html).

1. (Optional) Provision transit VIFs to access your private AWS resources through Direct Connect Gateway and [AWS Transit Gateway](https://docs.aws.amazon.com/whitepapers/latest/building-scalable-secure-multi-vpc-network-infrastructure/transit-gateway.html).

1. (Optional) Provision public VIFs to access your public AWS resources such as [Amazon Simple Storage Service](https://docs.aws.amazon.com/AmazonS3/latest/userguide/Welcome.html) and [Amazon API Gateway](https://docs.aws.amazon.com/apigateway/latest/developerguide/welcome.html). Connectivity can be Regional or global.
