What is Edge Computing?

Edge computing is a distributed computing model that moves data processing and application logic from central servers closer to users. It provides low latency and high speed.

Cloudflare Workers, Vercel Edge Functions, and AWS Lambda@Edge are popular edge computing platforms.

What is a CDN?

A CDN (Content Delivery Network) caches static content on servers around the world and serves it from the server closest to the user. It is critical for fast loading and low latency.

Cloudflare, Akamai, and Fastly are among the most popular CDN providers.

Edge Runtimes

Edge runtimes let you run JavaScript code at CDN edge locations. They offer fast startup and low resource usage thanks to V8 isolates.

Cloudflare Workers: 100+ locations Vercel Edge Functions: 30+ locations Deno Deploy: 30+ locations Fastly Compute: 60+ locations

Use Cases

Edge computing is ideal for personalized content, A/B testing, authentication, rate limiting, and API gateway scenarios.

Future and Trends

Edge computing will be increasingly used in IoT, real-time applications, and AI inference. With more compute power and lower latency, the edge is shaping the future of cloud computing.
