Amazon Web Services
In this AWS re:Invent 2023 session, Stephen Callaghan, a senior principal engineer with Amazon Infrastructure Services, discusses AWS's journey towards an intent-driven network infrastructure. He explains how AWS is evolving its network to meet increasing demands, focusing on goals like improved availability, consistency, and scalability. Callaghan introduces the concept of Intents - defined behaviors expected of the network - and how they're being implemented to manage AWS's complex infrastructure. He details the development of SIDR, a new routing protocol designed for ultra-large scale clusters, and AIDN (AWS Intent Driven Network), a management plane sitting atop multiple control planes. The talk concludes with insights into automated reasoning techniques AWS uses to ensure network reliability. This deep dive into AWS's networking innovations showcases how the company is preparing its infrastructure for future challenges, particularly in supporting machine learning workloads and the generative AI boom.
