Explore the rising importance of eBPF in cloud-native environments through this comprehensive conference talk. Dive into the core architecture of eBPF programs, learning how they attach and run safely in the kernel. Discover the components of the eBPF subsystem and gain practical knowledge on using utilities like bpftool, bcc tools, bpftrace, and libbpf to manipulate eBPF objects. Understand eBPF's benefits for observability and networking programmability in Linux and containers, with a focus on its applications in Kubernetes clusters. Learn about Cilium's optimized datapath and various eBPF use cases in the wild. Get equipped with the knowledge and tools to instrument clusters effectively, from load-balancing traffic to chasing metrics, and prepare to harness the power of eBPF in cloud-native environments.
