Why have we not created a service mesh in the kernel before? Some people have been semi-jokingly stating that kube-proxy is the original service mesh. However, it is not enough. So what's next?

This allows for eBPF implementation to continue to evolve with the service mesh community.

Drupal—an open source CMS—turned 20 years old recently, and has grown from a small student hobby project to an enterprise-grade digital experience platform running ~3% of the Internet. This talk will explore the many lessons learned (most of them the hard way ;)) in navigating an international open source developer community through various scalability challenges.
