Making Your Decision
When to Choose Fly.io
Developers building globally distributed applications that need to run close to users with VM-level control.
Fly.io excels at running applications globally at the edge. If you need your app running in 30+ regions with low latency, Fly delivers what edge functions can't.
Strengths
- True global edge deployment with VMs
- Excellent for latency-sensitive apps
- Run any Docker container anywhere
- Great for distributed databases
Limitations
- Steeper learning curve
- Less polished than Vercel/Netlify for static sites
- Requires more DevOps knowledge
When to Choose AWS Amplify
Teams already invested in AWS who want integrated hosting with other AWS services like Cognito, AppSync, and DynamoDB.
AWS Amplify is the right choice if you're building on AWS. The ecosystem integration is unmatched, but the complexity and learning curve make it less ideal for simple deployments.
Strengths
- Deep AWS ecosystem integration
- Powerful backend features (Auth, API, Storage)
- Good for full-stack AWS applications
- Mature enterprise features
Limitations
- Complex pricing model
- Steeper learning curve than competitors
- AWS console can be overwhelming
