Introduction to Kubernetes podcast
This episode of the Kubernetes podcast features an interview with Bill Mulligan, a community builder at Isovalent and a committer to Cilium. They discuss the importance of eBPF technology and how it functions as a way to run specified programs in the Linux kernel during certain events. The conversation also covers the role of Cilium as an ABPF-powered networking, observability, and security tool. The episode explores the evolution of Cilium from a connectivity layer for containers to a comprehensive solution for service mesh, network policy, and multi-cluster mesh. Additionally, the interview touches on the recent acquisition of Isovalent by Cisco and the future of Cilium as a bridge between traditional networking and cloud-native systems.
Cilium's Role in Cloud-Native Networking
Cilium is a comprehensive solution for cloud-native networking, providing service mesh, network policy, and multi-cluster mesh capabilities. By leveraging eBPF technology, Cilium enhances observability, security, and networking performance within Kubernetes environments. It offers features like connectivity between containers, secure network policies, and advanced observability using Hubble. Cilium's acquisition by Cisco signifies its growing importance in the networking industry and its potential to bridge the gap between cloud-native and traditional networking systems.
The Power of eBPF Technology
eBPF technology enables the execution of specified programs in the Linux kernel during specific events. As a low-level Linux kernel technology, eBPF allows for the addition of new functionality and enhances performance, scalability, and security in the cloud-native space. With the ability to extend the functionality of the Linux kernel, eBPF introduces a paradigm shift where changes can be implemented quickly, bypassing the lengthy upstream acceptance process. eBPF is gaining traction as a critical component in cloud-native infrastructures, providing advanced networking, observability, and security capabilities.
The Future of Cloud-Native Networking
As the cloud-native revolution continues to evolve, networking plays a crucial role in connecting systems and maintaining their security and observability. Cilium, powered by eBPF, is positioned as a key player in the future of cloud-native networking. It enables the extension of Kubernetes capabilities, provides comprehensive service mesh functionality, and bridges the gap between traditional networking and cloud-native systems. The recent acquisition of Cilium's parent company, Isovalent, by Cisco further solidifies Cilium's significance in the networking industry, promising exciting developments and innovations in the years to come.
Certification and Resources
Cilium offers the Cilium Certified Associate (CCA) certification through the Linux Foundation. The CCA certification tests individuals' knowledge of Cilium installation, configuration, architecture, network policy, service mesh, network observability, and EBP-F technology. It serves as an entry-level certification for those interested in expanding their knowledge of Cilium. Additionally, Cilium provides resources such as labs and materials to help users explore the capabilities and features of Cilium, empowering them to gain a deeper understanding of the project and its functionalities.
The Role of DaemonSets in Cilium
Cilium utilizes DaemonSets in Kubernetes to ensure its functionality runs at the kernel level without compromising Kubernetes abstractions. By utilizing eBPF technology, Cilium connects containers, provides network security, and enhances observability. The Cilium agent, installed as a DaemonSet on every node, loads and unloads eBPF programs responsible for networking, security, and observability within Kubernetes clusters. This approach enables Cilium to operate efficiently within the Kubernetes environment, allowing for network-level control and performance enhancements.
