The Cilium Story - Why We Created Cilium

The Cilium Story - Why We Created Cilium

Cilium is well known today but why did we create it? This talk takes us back to the origins of Cilium. Together, we explore the adventure that led to the creation of the first few lines of Cilium source code. What was the vision? How close was it to what Cilium has become today? As we make our way exploring the many Cilium milestones, we look back to Cilium's roots in Switzerland, the many surprises on the way, and the major milestones that put Cilium on the trajectory it is today.

  15. “We chose Cilium because
    we were looking for a simple
    solution, a resilient solution,
    and one which is ready for
    day two operations.“
    – Alex Berger, Chief Architect
    Cilium is a critical part of the
    Datadog network stack as it
    provides consistent Kubernetes
    networking across cloud
    providers as well as performant
    and secure communications,
    thanks to eBPF.

    specific application that
    initiated the connection.”
    – Bradley Whitfield,
    Senior Lead Platform Engineer
    “We choose Cilium as it
    supports Network Policies at
    Layer 3/4/7, Cloud agnostic
    & easy to deploy anywhere.”

    Connect!
    One Mesh to Connect Them All
    Principle #1:
    Combines all Cilium
    components into a single
    mesh:
    - Kubernetes Networking
    (CNI)
    - Cluster Mesh (Multi-Cluster)
    - Ingress & Egress Gateway
    - Load Balancer
    - Service Mesh
    Principle #2:
    Connects Kubernetes, VMs, and Servers across
