Understanding Edge Computing
Core concepts of edge for web applications.
- Edge locations: CDN points of presence globally
- Edge functions: Code that runs at edge
- Latency reduction: Processing near users
- Distributed logic: Not just caching, but computation
- Hybrid: Combine edge and origin processing
Edge Computing Use Cases
Where edge computing delivers value.
- Personalization: User-specific content at edge
- A/B testing: Variant selection at edge
- Geolocation: Location-aware experiences
- Authentication: Token validation at edge
- API responses: Dynamic content with edge caching
Edge Computing Platforms
Services offering edge computation.
Building Edge Functions
Developing code for edge execution.
- Lightweight runtime constraints
- Fast cold starts essential
- Limited memory and execution time
- Stateless design (or use edge storage)
- Efficient code for minimal latency
Edge Architecture Patterns
Integrating edge into website architecture.
- Edge-first: Edge as primary compute layer
- Hybrid: Edge for personalization, origin for data
- Cache augmentation: Edge enhances caching
- Edge middleware: Request/response transformation
- Progressive: Add edge capabilities incrementally
Edge Computing Considerations
Factors in edge adoption.
