The Craft of Open Source

Project Calico

Ben Rometsch and Matt Althauser sit down with Shaun Campton, Principal Engineer at Tigera, who shares his experiences as a core developer on Project Calico. He talks about their origins of moving out of the era of doing forklift moves into OpenStack and down the development of network splitting, focusing more on a dynamic firewall approach. He opens up on his experiences writing their first 10,000 lines of code, their identity-based policy, and the value they are offering to clients. Shaun also provides insights on what may be next for Kubernetes and how open-source projects must get ready for any change ahead.
