Cilium 1.14 - Effortless Mutual Authentication, Service Mesh, networking beyond Kubernetes, high-scale multi-cluster, and much more

Introduced in Cilium 1.14 is support for a much-requested feature: mutual authentication. From its inception, we looked at delivering an optimal effortless user experience to achieve mutual authentication. The result is simple: add 2 lines of YAML to your Cilium Network Policy, and that’s it – your workload communication is now secured with a mutual TLS handshake. Try it in this new Star Wars-inspired lab!

Learn all about Hubble for the Enterprise

This lab provides an introduction to Isovalent Enterprise for Cilium capabilities related to connectivity observability. This track primarily focuses on Hubble Flow events that provide label-aware, DNS-aware, and API-aware visibility for network connectivity within a Kubernetes environment using Hubble CLI, Hubble UI and Hubble Timescape, which provides historical data for troubleshooting.

In this scenario, we are going to simulate the exploitation of a nodejs application, with the attacker spawning a reverse shell inside of a container and moving laterally within the Kubernetes environment.   We will demonstrate how the combined Process and Network Event Data: identify the suspicious Late Process Execution tie the suspicious processes to a randomly generated External Domain Name trace the Lateral Movement and Data Exfiltration of the attacker post-exploit

Encryption is required for many compliance frameworks. Kubernetes doesn’t natively offer pod-to-pod encryption. To offer encryption capabilities, it’s often required to implement it directly into your applications or deploy a Service Mesh. Both options add complexity and operational headaches. Cilium actually provides two options to encrypt traffic between Cilium-managed endpoints: IPsec and WireGuard. In this lab, you will be installing and testing both features and will get to experience how easy it is to encrypt data in transit with Cilium.

[07:46] In this video, learn about a new Cilium 1.14 feature - support for WireGuard alongside L7 Network Policies!

Form3 is building out a multi-cloud strategy. To avoid cloud vendor lock-in, they chose Cilium with Kubernetes. It also simplifies daily operations and troubleshooting.

In this tutorial, users will learn how to deploy Isovalent Enterprise for Cilium on your AKS cluster from Azure Marketplace on a new cluster and also upgrade an existing cluster from an AKS cluster running Azure CNI powered by Cilium to Isovalent Enterprise for Cilium.

One of the most important thing when running applications in an environment like Kubernetes is to have good observability and deep insights. However, for many organizations it can be challenging to update existing applications to provide the observability you need. With Cilium, you can use the Hubble Layer 7 visibility functionality to get Prometheus metrics for your application without having to modify it at all. In this lab you will learn how Cilium can provide metrics for an existing application with and without tracing functionality, and how you can use Grafana dashboards provided by Cilium to gain insight into how your application is behaving.

Cilium Mesh - One Mesh to Connect Them All. Connect Kubernetes, VMs, and Servers across Cloud, On-Prem, and Edge.

Migrating to Cilium from another CNI is a very common task. But how do we minimize the impact during the migration? How do we ensure pods on the legacy CNI can still communicate to Cilium-managed during pods during the migration? How do we execute the migration safely, while avoiding a overly complex approach or using a separate tool such as Multus? With the use of the new Cilium CRD CiliumNodeConfig, running clusters can be migrated on a node-by-node basis, without disrupting existing traffic or requiring a complete cluster outage or rebuild. In this lab, you will migrate your cluster from an existing CNI to Cilium. While we use Flannel in this simple lab, you can leverage the same approach for other CNIs.
