Is Vercel just AWS? A detailed breakdown

Decloak is an AI-powered web security intelligence platform that scans a site's HTTP/TLS posture, JavaScript, and third-party scripts to produce a report anyone can read. This guide is part of Decloak's library of practical, source-backed security guidance.

Key takeaways

• Vercel uses Amazon Web Services for raw compute and storage.
• Vercel adds a proprietary global edge network, anycast routing, DDoS protection, and a custom Fluid compute model.
• The platform abstracts AWS away from developers, providing a higher - level developer experience.

Is Vercel just AWS?

No. Vercel runs many services on top of Amazon Web Services, but it also builds and operates a large, proprietary edge and platform layer that sits in front of AWS.

How does Vercel use AWS?

Vercel’s compute regions (e.g., iad1, cle1) map to AWS regions and run on AWS - based micro - VMs such as Firecracker. Build containers, serverless functions, and storage all rely on AWS hardware.

What does Vercel add on top of AWS?

• Global edge network - Over 126 points of presence with anycast routing, private fiber backbone, TLS termination and DDoS mitigation that are owned by Vercel.
• Fluid compute - A custom serverless model that pre - warms functions, caches byte - code and routes traffic through Vercel’s Functions router instead of raw AWS Lambda.
• Hive build infrastructure - Vercel - managed KVM and Firecracker micro - VMs that provision isolated build containers in seconds.
• Secure Compute VPC peering - Dedicated static - IP networks that can peer directly with a customer’s AWS VPC, providing a private link layer.
• Observability and failover - Vercel’s routing intelligence, regional failover tables and Edge Config store operate independently of AWS routing.

Comparison: Vercel vs raw AWS services

Why the distinction matters for developers

• Zero configuration - Developers push code and Vercel automatically provisions the needed AWS resources without manual IAM or EC2 setup.
• Performance - Requests hit Vercel’s edge cache before any AWS region, reducing latency compared to a straight CloudFront + Lambda setup.
• Cost model - Fluid compute’s concurrency and pre - warming reduce cold - start charges that are typical with vanilla Lambda.
• Security - Vercel’s managed DDoS/WAF and private backbone add protection layers not present in a default AWS deployment.

Bottom line

Vercel leverages AWS for the underlying hardware, but it builds a complete, proprietary edge and platform layer that abstracts AWS away from the developer. Therefore Vercel is not simply AWS; it is a higher - level platform that runs on top of AWS while adding many of its own services.

How can Decloak help monitor Vercel security?

Decloak’s free scan can quickly assess the public surface of a Vercel - hosted site, checking HTTP/TLS posture, static HTML, rendered network behavior, and JavaScript libraries. The vibe - coded platform security layer also detects common misconfigurations in platform - as - a - service stacks, such as exposed service_role keys or mis - configured VPC peering that could leak data. Running a scan gives you a graded, shareable report in about 15 seconds, letting you catch Vercel - specific exposure before attackers do.
