When you need to overcome your fear and build your own data-driven eBPF firewall - Niek Temme

Why and how we built a custom eBPF firewall for our use case of running up to ten thousand firecracker micro vms per node, 1M Envoy clusters and receiving updates through a go control plane.

This session is about a production use case that highlights the performance and flexibility of XDP, overcoming our fear of eBPF programming and information exchange between our control plane and eBPF.

The use case is for Bubl, a pre-launch startup with a mission to restart privacy safe innovation on personal data, by allowing innovative companies to create privacy safe services in the cloud.

By providing insight into our journey, our challenges and the solution we came up with we can help other companies get started with eBPF for networking and show how to integrate its flexibility with other applications.

Covered topics
10.000 vm’s per node, 1M Envoy TLS/SNI clusters, IPv6 load balancing
