AWS Cloud WAN: a cloud-native attach paradigm to simplify global connectivity and segmentation

For the uninitiated, AWS Cloud WAN is a fundamental networking innovation that allows customers to define global network policies that set up multi-region connectivity and segmentation. For our customers, this translates to a much simpler cloud-native connectivity model, devoid of complex peering constructs at the networking layer and allowing them to focus on communication and security relationships between workloads and applications.

Autonomous Multicloud Transit and Cloud WAN

Prosimo’s autonomous multicloud transit leverages these powerful cloud-native constructs to set up global connectivity across regions and even extend them into the hybrid cloud. Security, access, and performance are not bound to an external network provider’s reach; instead, the transit network scales elastically to provide these outcomes wherever users and applications have a presence. All this is possible because Prosimo’s solution orchestrates cloud-native constructs to take advantage of AWS’s global presence. Imagine having your own private post office network doing its job while you as a customer figure out where to send your packages, how securely they get there, and how fast they get there.

Zero Trust with Cloud WAN

With Prosimo’s full-stack cloud transit, customers migrate global connectivity from hub-and-spoke and peering models, then connect VPCs to Cloud WAN. Prosimo’s full-stack transit not only orchestrates this underlying cloud-native connectivity in the customers’ infrastructure but also makes these applications and workloads accessible globally to users in a zero-trust manner. Compare and contrast this with a legacy, tunnel-based approach: this would be akin to a modern post office network but using it to deliver mail via horseback.

Setting up a global transit network

Another customer challenged Prosimo with building a global transit network that internal customers could connect to and get zero trust connectivity for users accessing applications and workloads communicating internally with shared services. Prosimo’s cloud-native architecture was the perfect fit for this global, elastic transit that had to work across shared governance models while staying faithful to the cloud-native mandate. Prosimo is cloud-native by design; we orchestrate constructs such as AWS Transit Gateway (TGW) and Cloud WAN for hybrid and inter-cloud region connectivity. Prosimo makes it easy to incorporate new constructs and migrate to them seamlessly.

Configuring Prosimo to use Cloud WAN

Using Cloud WAN for connectivity as a part of the Prosimo infrastructure is extremely simple. While onboarding an application, customers choose the Cloud WAN option and the core network attach points the infrastructure will use, and that’s it! Prosimo will automagically set up the underlying infrastructure.

The value of Prosimo and Cloud WAN

The caveat in all of this is that in order to realize meaningful user experience, the operational model for cloud networking – the approach to creating cloud networks regardless of cloud – has to change. Just as application infrastructure has changed from dedicated servers to virtual servers, and now to server-less, we have to change how we create, maintain, and rationalize the network. The network has not received the upgrades that the application infrastructure has, until now.
