While the training phase is notoriously resource‑intensive, serving these models at low latency—especially in a distributed environment—poses a separate set of engineering challenges. Kubernetes (K8s) has emerged as the de‑facto platform for orchestrating containerized workloads at scale, but it was originally built for stateless microservices, not for the GPU‑heavy, stateful inference pipelines that LLMs demand. ...
Introduction Kubernetes has become the de‑facto platform for running containerized workloads at scale. While most developers interact with the API server, pods, and services daily, the underlying networking layer remains a black box for many. Yet, a solid grasp of how Kubernetes networking works internally is essential for backend engineers who need to: Diagnose connectivity issues quickly. Design resilient multi‑tier applications. Implement secure network policies. Choose the right CNI plugin for their workload characteristics. This guide dives deep into the internals of Kubernetes networking, covering everything from the Linux network namespace that isolates each pod to the sophisticated routing performed by kube-proxy. Along the way, you’ll find practical code snippets, YAML examples, and real‑world context that you can apply to production clusters today. ...
