Kubernetes networking : is there a cheetah within your Calico?
Even faster kubernetes clusters with Calico, VPP and memif
Kubernetes is great, containers are lightweight & disposable, networking is simple yet powerful. But when it comes to network oriented applications, oh that can be slow !
That’s how the Calico/VPP integration first came up, as a way to address performance bottlenecks, making VPP’s performance the motor of Calico’s functionalities in Kubernetes. It speeds up container networking, but also allows us to expose even faster functionalities directly to the applications. So with this in place, how can we go even faster, while still preserving the Kubernetes abstractions ?
We’ll present how applications can leverage userspace interfaces, what this allows regarding network performance & additional functionalities and how the Calico/VPP integration makes this happen under the hood.

Chris is a developer advocate at Project Calico/Tigera, where he champions user needs to support Project Calico’s users and contributor community. He has worked in networking since 2000. After realising that a per-device CLI is not a scalable solution for a large environment, he took an early interest in infrastructure-as-code approaches and large-scale automation and continues to have a special interest in pursuing technologies in these areas.
Nathan is a software engineering at Cisco focusing on container networking & cloud app performance. After spending time deploying & scaling web apps he took interest in converting his love for script based infras into cloud native approaches, and now contributes to the building blocks of line rate container networking. He’s a maintainer of the Calico/VPP integration, and of VPP’s QUIC stack.
