Kubernetes Networking for Network Engineers - C2C034

Cables2Clouds

What if the future of cloud-native networking could revolutionize everything you thought you knew about Kubernetes? Join us on this episode of Cables 2 Clouds as we continue our "Cloud Demystified" series with a deep dive into Kubernetes networking. We're thrilled to have Nicolas Vibert, a seasoned pro from Isovalent with nearly two decades of experience at Cisco, VMware, and HashiCorp. Together, we explore the essentials of Kubernetes networking through the innovative lens of Cilium, a CNI specifically designed for cloud-native environments.
Nico shares his unique journey of learning Kubernetes from a network engineer’s perspective, emphasizing the critical role of hands-on experience and mentorship. We also discuss the creation of hands-on labs and educational materials tailored for network engineers. This segment is loaded with analogies to help traditional network professionals grasp key Kubernetes concepts with ease.
Ever wondered how Kubernetes orchestrates its complex networking operations? We break down the intricacies of the Kubernetes control plane, likening it to traditional network engineering concepts for clarity. Discover the limitations of Kubernetes' default networking tool, kube-proxy, and why modern CNIs like Cilium offer a more efficient solution for large-scale deployments. Nico explains how Cilium leverages eBPF maps for effective traffic routing and load balancing within Kubernetes clusters. Tune in for invaluable insights into the evolving landscape of cloud-native networking solutions.
