Cost Control Strategy: Reducing Bandwidth Costs by 30%+ with Smart Caching

As businesses grow, bandwidth bills often outpace expectations. Apart from negotiating lower prices, technical optimization is the root cure.

1. Smart Compression: Brotli vs Gzip

We recommend enabling Brotli compression site-wide. Data shows that for HTML/CSS/JS text resources, Brotli saves 15% - 20% more size than Gzip. This means a direct 20% reduction in traffic billing. CDN Engine supports dynamic handling based on client `Accept-Encoding` headers.

2. Resource De-duplication

In user upload scenarios (like cloud drives, albums), duplicate files consume massive storage and bandwidth. CDN Engine's object storage gateway supports real-time SHA-256 based deduplication. Even if users upload `funny-cat.mp4` 100 times, we only store 1 copy on disk and transfer it once from origin.

3. Aggressive TTL Strategies

This is the simplest yet most overlooked point. Analyze your access logs, and for those APIs that "actually don't change often" (like configs, public lists), try setting TTL from 0 to 60 seconds. This tiny change can reduce backend load by 99% while significantly lowering internal server bandwidth consumption.
