Kubernetes Observability in Action Harnessing Innovative Observability using eBPF and Cilium In today's fast-paced digital world, technology plays a vital role in shaping our lives and societies. The rapid evolution of technology has led to the development of new tools and techniques that enable us to observe and analyze complex systems like never before. One such tool is Kubernetes observability, which provides insights into the behavior of distributed systems, enabling developers and operators to identify issues, optimize performance, and improve overall system health. This article will delve into the concept of Kubernetes observability, its importance, and how it can be harnessed using innovative tools like eBPF and Cilium. The Need for Observability Observability is the ability to gain insights into the internal workings of a system, allowing us to understand how it functions, identify issues, and make improvements. In the context of Kubernetes, observability is crucial for managing and maintaining large-scale distributed systems. With Kubernetes becoming the de facto standard for container orchestration, understanding how to observe and troubleshoot these systems is essential for anyone working with them. The Evolution of Technology Technology has evolved rapidly over the past few decades, transforming the way we live, work, and communicate. From mainframes to personal computers, to mobile devices and cloud computing, each step in this journey has brought about significant changes in how we interact with technology. The rise of Kubernetes as a container orchestration platform represents another significant milestone in this evolution.
