Kubernetes networking is often considered the “final boss” for system architects. While the platform abstracts away much of the complexity of container orchestration, the underlying networking model is a sophisticated web of IPAM, virtual interfaces, routing tables, and netfilter rules. Understanding how a packet travels from a user’s browser to a container deep within your cluster is essential for building scalable, secure, and resilient systems. In this guide, we will peel back the layers of the Kubernetes networking stack. ...

In the era of social media and character limits, URL shorteners like Bitly and TinyURL have become essential infrastructure. While the core functionality—mapping a long URL to a short one—seems simple, building a system that can handle billions of requests with millisecond latency and 99.99% availability is a classic system design challenge. In this post, we will walk through the architectural blueprint of a scalable, resilient URL shortener. 1. Requirements and Goals Before diving into the architecture, we must define our constraints. ...
