In this 3-part webinar series, Isovalent developers tell the story of how and why eBPF was created, how eBPF works and how Cilium was born.

Capital One needed to scale their PaaS to multiple teams - but required secure network isolation, visibility and minimal performance overhead. Isovalent Cilium Enterprise met all requirements and scaled past the iptables limits. Hubble’s additional observability capabilities helped their teams to do more from the start.

Isovalent helped PostFinance to build a scalable Kubernetes platform to run mission-critical banking software in production. By migrating to Cilium as the default CNI for kubernetes, they were able to solve their challenges regarding scale, observability and latency. The network was made visible, improving troubleshooting, enabling forensic analysis and transparently encrypt network traffic.

Microsoft and Isovalent enter a strategic partnership to bring eBPF-based Cilium and Tetragon to Azure and AKS.

In this tutorial, you'll learn how easy it is to encrypt Kubernetes traffic using Cilium Transparent Encryption with IPsec and WireGuard.

[04:45] Tune in to our experts Nikolay Aleksandrov (speaker) and Daniel Borkmann comparing BBR-based congestion control to Linux' default CUBIC for Pods. The BBR-based congestion control for Pods has been added in Cilium 1.12 as a new feature for Cilium's Bandwidth Manager and for the first time enables Pods to use BBR in practice. Using a real-world adaptive video streaming use case they will compare two different network conditions - high-speed long-haul links with large BDP and last mile networks at the edge of Internet - and discuss the results.
