FAQs
What is a modern content delivery network, and how is it different from a traditional CDN?
A modern content delivery network (CDN) goes beyond caching static files. It intelligently routes requests across a global edge network, accelerates dynamic content and APIs, reduces latency, and gives teams real-time control over content delivery.
Unlike traditional CDNs that may require longer cache refresh cycles or manual configuration changes, modern platforms enable capabilities like instant cache invalidation, programmable edge logic, real-time observability, and intelligent traffic management. These features help organizations deliver fast, reliable experiences for websites, applications, streaming media, APIs, and AI-powered workloads while reducing demand on origin infrastructure.
How does edge delivery improve website, API, and AI application performance?
Edge delivery improves performance by processing and serving content closer to end users instead of routing every request back to the origin server. This reduces latency, lowers time to first byte (TTFB), and decreases origin load.
For APIs and AI-powered applications, edge delivery also helps maintain responsiveness during traffic spikes by intelligently caching content, optimizing request routing, and providing programmable control at the edge. This enables faster user experiences while improving scalability and infrastructure efficiency.
Why is content delivery important for AI-powered applications?
AI-powered applications rely on fast, reliable infrastructure to deliver prompts, APIs, models, and generated responses with minimal latency. As AI usage grows, infrastructure must also support unpredictable traffic patterns, dynamic workloads, and real-time content updates.
A modern content delivery platform helps accelerate AI applications by optimizing API performance, reducing origin requests, intelligently routing traffic across the edge, and maintaining availability during periods of high demand. This enables developers to build responsive AI experiences while improving scalability and operational efficiency.
How do I choose the right CDN for my business?
The best CDN depends on your performance, security, scalability, and operational requirements.
When evaluating CDN providers, consider:
Global network performance and latency
Dynamic content and API acceleration
Cache invalidation speed
Traffic management capabilities
Real-time observability
Edge programmability
Security integrations
Reliability during traffic spikes
Support for AI and modern application architectures
Organizations that require real-time control, programmable edge capabilities, and fast content updates often prioritize platforms that combine delivery, observability, and edge computing in a single architecture.
How does a CDN support reliable and resilient digital experiences?
Modern CDN infrastructure can improve reliability by intelligently routing traffic and adapting when failures occur. Fastly's self-healing infrastructure detects failures and reroutes traffic in sub-seconds, while its infrastructure is continuously optimized for resilience and availability without compromising performance.
