Build a Free-Tier Image Pipeline with Alibaba Cloud OSS + CDN

Описание и применение

Создайте OSS‑bucket, загрузите изображения через SDK, подключите CDN и настройте кэширование и обработку изображений. Это уменьшит нагрузку на сервер и снизит расходы.

Задача

Managing uploaded images on an app server leads to disk bloat, high bandwidth costs, and backup challenges.

Результат

The pipeline reduces server load, scales automatically, and keeps costs low by leveraging OSS storage and CDN caching.

Рабочий процесс

• Create an OSS bucket with private access and public-read pattern
• Upload images via the Python OSS SDK from the backend or use STS for client-side uploads
• Set up a CDN domain pointing to the OSS bucket as origin
• Enable OSS image processing for on-the-fly transformations
• Configure CDN cache TTL (e.g., 7 days)
• Implement server-side upload validation (size, MIME, deduplication)
• Set lifecycle rules to move old originals to cold storage
• Log access for abuse detection

Доказательства

Object storage (OSS) is built for exactly this job: Pay per gigabyte stored and per request — no idle capacity
