Comprehensive SRE Guide for Summer and Winter High‑Load Periods in an Online Education Platform
This document outlines a comprehensive SRE‑driven operational framework for ensuring stable, high‑availability online education services during peak summer and winter periods, detailing pre‑, during‑, and post‑maintenance phases, architectural principles, load testing, monitoring, capacity management, safety hardening, chaos engineering, incident response, and post‑mortem practices.
The guide presents an SRE‑oriented operational strategy aimed at maintaining stable, high‑availability online education services when user traffic surges during summer and winter vacation periods.
It divides the protection workflow into three stages—pre‑protection, protection in‑progress, and post‑protection—each with specific responsibilities and checklists.
Key architectural principles include N+1 redundancy, rollback capability, feature toggle configuration, built‑in monitoring, multi‑active data‑center design, resource isolation, and horizontal scalability.
Load testing is performed through comprehensive full‑link interface tests, covering live‑streaming scenarios split into 13 micro‑scenes, as well as platform‑wide stress tests, to identify bottlenecks in CPU, network, disk I/O, and business logic.
Monitoring dashboards are reinforced across physical, service, data, and business layers, with dedicated screens for gateway QPS, message system health, and live‑classroom metrics, ensuring real‑time visibility during peak periods.
Security hardening addresses external attacks and injection risks by employing code reviews, WAF integration, and HTTPS enforcement.
Chaos engineering practices, including fire‑drill checklists and simulated failures (Chaos Monkey, latency injection, etc.), are introduced to validate system resilience and improve fault‑tolerance.
Change‑control policies restrict online operations to specific time windows, require advance reporting, and mandate impact assessments before any deployment during critical hours.
On‑call duties cover rapid alert response, daily reporting, and coordinated incident handling procedures, with clear escalation paths and root‑cause analysis responsibilities.
Post‑event activities focus on detailed incident records, post‑mortem reviews, knowledge sharing, and the continual enrichment of a centralized SRE knowledge base for future high‑load events.
