There’s a reason Calico is the most widely adopted network and network
security solution for Kubernetes – you can do amazing things with it.

Lets dive into some of the basics of Calico networking with OpenShift,
and discuss/demo some of the advanced networking capabilities, including:

  • Creating zone based architectures with selective IP address allocation
    by zone, namespace or pod
  • Enabling selective pod connectivity without NAT to/from external
  • Making Service Cluster IP’s natively reachable from outside the cluster
  • ECMP Anycast for native load balancing to services from outside the cluster
    without needing external load balancers
  • Connecting multiple clusters together with or without encapsulation
  • Deploying massive OpenShift clusters (with hundreds to thousands of nodes)
