For years, Amazon CloudFront has been the default Content Delivery Network (CDN) for systems deployed within the AWS ecosystem. However, over the past 12 months of troubleshooting European network routing profiles for our clients, we have stopped recommending it as the baseline choice for B2B SaaS platforms targeting EU markets.
The Edge Network Latency Gap
Our routing tests across major European cities (Frankfurt, Munich, Amsterdam, Paris) revealed that CloudFront's default routing profiles can introduce unnecessary latency hops compared to edge networks that route traffic closer to local ISPs. This issue is magnified when your SaaS platform requires dynamic GraphQL and API routing updates, where caching benefits are minimal.
GDPR Compliance & Certificate Locality
Under GDPR rules, data paths and TLS negotiation parameters must comply with strict locality controls. Configuring CloudFront to guarantee that TLS termination and requests remain entirely within the European Economic Area (EEA) requires selecting premium price classes, which increases network costs without improving performance. Alternative CDNs allow you to restrict TLS execution to European zones out of the box.
Alternative Architectures
For B2B SaaS platforms targeting European users, we recommend using Anycast-based routing platforms that support local TLS negotiation and forward request packets directly over dedicated fiber connections. This design typically cuts API latency times by 40-80ms while simplifying certificate storage controls.
