How Calico Networking Works in OpenShift

Published May 6, 2020

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 workloads
  • 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)
