Network policy at scale; scaling Calico to 15k+ nodes and 10k network policies 

Shaun Crampton navigates the challenges and solutions in scaling Calico, to unprecedented levels.
A year ago, Shaun faced the formidable task of enhancing Calico to support over 15,000 nodes and 10,000 network policies without sacrificing performance.
This video gives you an in-depth overview of scale-out architecture (which should be interesting whether you’re looking for a network policy solution or just to see how we scaled our application on top of Kubernetes), how it’s evolved, how we do (mocked) high-scale testing, and a rundown of the improvements in v3.27 that take it to the next level.
Key Highlights:
🚀 Extensive Scalability: Insights into expanding Calico to handle 15,000+ nodes.
🛠️ Architecture Evolution: Explore the advancements in Calico's network policy engine.
🧪 Testing at Scale: Techniques for mocked high-scale testing and performance validation.
📈 Version 3.27 Improvements: Discover the significant enhancements that optimize performance and scalability.
