When a system faces a sudden hundred‑fold increase in QPS, this guide walks backend engineers through emergency response, root‑cause analysis, robust design techniques, scaling options, and pressure testing to keep services stable and performant.
This document outlines the standards, evaluation dimensions, and implementation process for dual‑stream construction in big‑data pipelines, describes high‑fidelity pressure‑testing methods and objectives, and provides migration procedures for business units not participating in the tests.
This article describes how to implement a traffic management system using service isolation to address challenges in full-link pressure testing, parallel feature testing, and online gray release.
The article explains how Xianyu guarantees high‑availability of its core Ha3‑based search engine through independent gateway deployment, multi‑datacenter disaster recovery, traffic isolation, comprehensive monitoring, pressure testing, gray releases, and automated/manual failover, enabling rapid issue detection, recovery, and continuous service stability.
JD.com's R&D team completed a full-linkage pressure test for the 618 promotion, addressing hardware shortages by optimizing existing systems and preparing 24/7 monitoring.
