In the world of content delivery, speed is everything. But how do Content Delivery Networks (CDNs) actually achieve such high speeds? The secret lies in their caching architecture.
The Three-Level Cache Strategy
Our CDN Engine employs a sophisticated three-level caching mechanism to ensure optimal performance for both hot and cold data.
- L1 (Memory): Ultra-fast access for the most popular content.
- L2 (SSD): High-speed storage for warm data.
- L3 (HDD): Massive capacity for long-tail content.
This tiered approach allows us to balance cost and performance effectively, ensuring that your users always get the fastest possible response times.
