Distributed Web Scraping Architecture for Market Intelligence

Objective

Build a resilient system to track competitor pricing across 50+ global e-commerce sites for market intelligence.

Developer Approach

Use Headless Playwright/Puppeteer orchestrated via Docker Swarm. Instead of a single IP, implement a Proxy Rotation layer to avoid bot detection and distribute load.

Technical Optimization

Implement Content-Addressable Storage (CAS) for HTML snapshots to avoid saving duplicate data, reducing storage costs by 60% during long-term tracking.
