AWS Cloud WAN changed the way how AWS networking is done....but during AWS re:Invent 2025, AWS announced several enhancements to AWS Cloud WAN. The most significant of these is the introduction of Cloud WAN Routing Policies, which enables customers to centrally control how traffic flows across their global networks. These policies provide capabilities such as route filtering, route summarisation, and BGP path manipulation, allowing for finer-grained routing control in multi-region and hybrid environments.

This presentation will break down the different core architectural building blocks of AWS Cloud WAN, explain how to design and implement multi-region traffic inspection, and walk through practical use cases that leverage the newly announced routing policy capabilities. At the end of session you will be able design and implement complex Cloud WAN architectures
