Quick Verdict
Choose Amazon Web Services if you need a comprehensive, enterprise-grade cloud platform with a vast service catalog. Choose Fly.io if your primary goal is to deploy and run low-latency, globally distributed applications with minimal operational overhead.
AWS is a full-service cloud infrastructure provider, offering over 200 services from compute to AI, requiring more architectural and management expertise. Fly.io is a developer-centric platform focused on running stateful applications close to users via a global network of lightweight servers, abstracting away much of the underlying infrastructure. Both use pay-as-you-go pricing, but AWS's model is complex with many services, while Fly.io's is simplified and application-centric. AWS targets organizations of all sizes needing a complete cloud toolbox, whereas Fly.io targets developers and startups prioritizing fast, global deployment and simplicity.

Choose Amazon Web Services if...
AWS is the better choice for enterprises or projects that require a vast, integrated ecosystem of services (e.g., specialized data analytics, machine learning, or enterprise security tools) and have the expertise to manage it. It is also the default for complex, multi-service architectures that need fine-grained control over every layer of the infrastructure.
Choose Fly.io if...
Fly.io is the better choice for developers or small teams who want to deploy a full-stack application or database globally with minimal configuration, using a simple CLI and Docker. It is ideal for applications where low-latency user experience is critical and the team wants to avoid the complexity of managing a traditional cloud vendor's global networking and orchestration.
