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
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)
