This roundup covers Netflix’s switch to Kueue for Kubernetes-native batch compute, an engineer’s workflow for long-running coding agents, and Zalando’s in-process client load balancer handling over a million requests per second. It also explains Zepto’s dual-sequence re-ranker for real-time personalization, strategies for catching data issues early, why technically strong teams still miss business impact, and a new storage/workload architecture taxonomy—plus a Databricks metrics webinar and SQL tools.

This article breaks down how to design a web system for scale, starting with scope, use cases, and constraints. It then walks through high-level and component design, scaling strategies (caching, load balancing, replication), performance tuning, reliability, and front-end considerations.
