Cilium is an open-source software for providing, securing, and observing network connectivity between container workloads - cloud-native, and fueled by the revolutionary Kernel technology eBPF.

In this workshop, we will review the following:

- Deployment of Cilium (including Hubble) on a KinD Kubernetes cluster

- Deployment of the booking application

- Looking at the service-to-service communication using the Hubble UI and then looking at the gRPC endpoint which provides the data used by the UI to build the graph

- Leveraging network policies to secure service-to-service communications and diving into how L4 and L7 policies are enforced (through eBPF and Envoy)
