fastly vs cloudfront

Here’s the short version:

Fastly vs CloudFront

Fastly

Best for: teams that want high control, low latency, and real-time edge customization.

Strengths

• Very fast CDN performance, especially for dynamic content
• Powerful edge compute and request manipulation
• Excellent real-time caching controls and instant purging
• Great observability/logging
• Popular with engineering-heavy teams

Tradeoffs

• Can be more complex to configure
• Often less “plug-and-play” than CloudFront
• Pricing can feel less predictable depending on traffic patterns

---

CloudFront

Best for: teams already in AWS, or those wanting tight AWS integration and simpler operational fit.

Strengths

• Deep integration with AWS services like S3, ALB, WAF, Lambda@Edge, CloudWatch
• Easy choice if your infrastructure is already on AWS
• Global CDN with strong reliability
• Often simpler to adopt for AWS-native workloads

Tradeoffs

• Edge customization is generally less flexible than Fastly
• Configuration can feel clunky
• Some advanced behaviors are harder to implement cleanly
• Debugging and observability can be less straightforward than Fastly

Choose Fastly if:

• You need sophisticated edge logic
• You care a lot about real-time cache control
• You want very strong debugging and analytics
• Your app benefits from hands-on CDN tuning

Choose CloudFront if:

• You’re already using AWS heavily
• You want native integration with AWS security and compute
• You prefer a more straightforward platform choice
• Your use case is standard CDN + AWS origin protection
