# Serverless at the Edge: Building Low-Latency Global Applications

> Learn to build low-latency global applications using serverless edge computing with Cloudflare Workers, Lambda@Edge, and more.

## The Edge Computing Revolution

As user expectations for instant responses grow, traditional cloud architectures face latency challenges. Edge computing brings computation closer to users, while serverless eliminates infrastructure management.

### Key Technologies

- **Cloudflare Workers**: JavaScript at 300+ global locations
- **AWS Lambda@Edge**: Functions at CloudFront edge locations
- **Vercel Edge Functions**: Seamless integration with Next.js
- **Deno Deploy**: TypeScript-first edge runtime

### Use Cases

- API routing and authentication
- Personalization and A/B testing
- Image optimization and transformation
- Real-time data processing

### Architecture Patterns

Successful edge architectures typically follow these patterns:

- **Edge-First**: Handle as much as possible at the edge
- **Hybrid**: Edge for routing, origin for complex logic
- **Cache-Heavy**: Maximize cache hit rates at edge

### Cost Considerations

While edge computing offers performance benefits, careful cost analysis is essential. Monitor request volumes and optimize for cacheable responses.
