AWS CloudFront vs AWS Global Accelerator
AWS CloudFront and Global Accelerator both improve global application performance, but they serve different purposes and use different architectures.
| Feature | AWS CloudFront | AWS Global Accelerator |
|---|---|---|
| Purpose | Content delivery (CDN) | Global traffic routing and acceleration |
| Optimized for | Caching static and dynamic content | Directing users to the closest AWS region |
| Use Case | Web assets (images, videos, APIs) | Multi-region applications needing low-latency traffic routing |
| Latency | Reduced through caching | Reduced by routing traffic via AWS backbone |
| Protocol | Works over HTTP/HTTPS | Works over TCP/UDP |
| Routing Method | Uses Edge Locations worldwide | Uses Anycast IPs to route traffic dynamically |
1. Example: Global Website with Static and Dynamic Content
- A news website serves articles, images, and videos to users worldwide.
- Solution with CloudFront:
- Static content (images, CSS, videos) is cached in CloudFront Edge Locations.
- Dynamic content (API responses) is also delivered with low latency by integrating with origin shielding.
- Benefit: Improves performance by reducing direct origin requests.
Architecture
User Requests --> CloudFront Edge Location (Cache) --> Origin (S3 or EC2)2. Example: Multi-Region API for a Banking Application
- A banking app needs users in Europe and Asia to access an API hosted in us-east-1 and ap-southeast-1.
- Solution with Global Accelerator:
- Users are routed to the nearest healthy region (e.g., Europe → eu-west-1, Asia → ap-southeast-1).
- If us-east-1 fails, traffic is automatically rerouted to ap-southeast-1.
- Benefit: Ensures low-latency and high availability.
Architecture
User Request --> Global Accelerator Anycast IP --> Closest AWS Region API Endpoint3. Example: Gaming Application with Real-Time Multiplayer
- A global multiplayer game requires real-time responsiveness.
- Solution with Global Accelerator:
- Players connect using Global Accelerator Anycast IPs, which route them to the closest Game Server.
- Low-latency network paths ensure minimal lag.
- Benefit: Global users get a seamless gaming experience.
Architecture
User Request --> Global Accelerator Anycast IP --> Nearest Game Server RegionWhen to Use?
✅ Use CloudFront when serving static or dynamic web content (CDN use case).
✅ Use Global Accelerator for multi-region applications needing low latency (e.g., APIs, real-time systems).
