Didi’s observability platform leverages non‑intrusive eBPF probes to automatically capture and validate service‑to‑service call tuples, supplement missing SDK data, achieve roughly 80 % core‑path coverage, and address verification challenges while planning future user‑space VM hooks and deeper MTL integration.
DeeTune is Baidu’s eBPF‑based cloud‑native network framework that automatically builds complete service topologies, records configurable inter‑service traffic, and provides non‑intrusive metric monitoring with minimal CPU and memory overhead, enabling efficient fault localization and performance analysis across heterogeneous PaaS and container environments.
The article explains the new Kubernetes v1.17 topology‑aware service routing feature, describing its purpose, underlying concepts such as topology domains and endpoint slices, the implementation details in kube‑proxy, how to enable it with feature gates and topologyKeys, and the practical benefits of reduced network latency and cost.
