## Resource

Episode 76 of Networking Tech with Fexingo dives into eBPF, the kernel technology that gives network engineers unprecedented visibility into traffic flows without changing application code. Lucas and Luna walk through the network observability startup Cilium and its eBPF-based approach to service mesh and security policies at scale. They discuss how companies like ByteDance and Capital One use eBPF to reduce latency by 40% and cut CPU overhead for network monitoring. The hosts also explore the trade-offs: a steep learning curve and potential kernel stability risks. With practical examples from production deployments, this episode explains why eBPF is the hottest tool in cloud-native networking since Kubernetes. #eBPF #Cilium #NetworkObservability #KernelProgramming #CloudNative #Kubernetes #ServiceMesh #ByteDance #CapitalOne #LinuxKernel #BPF #NetworkPerformance #Latency #SecurityPolicies #Technology #NetworkEngineering #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
