Data Center Networking for AI and Cloud

Welcome to the NextGenInfra Data Center Networking for AI and Cloud Showcase!

As the world invests multiple hundreds of billions to trillions of dollars in data center build out for AI, what's the role of networking? How should networking serve both AI and Cloud workloads? Will the shift from pre-training to post-training to test-time/inference-time scaling change the data center computing and networking requirements? So many questions, but do we know the answers?

To help our readers, we've captured insights from the leading thinkers in the data center networking ecosystem here in our showcase. The content in the videos and our report highlight the state-of-the-art in networking scale-up, scale-out, and scale-outside. What's scale-outside? Download the report to find out!
