Deploy your AWS app to Fly.io
Step-by-step deployment help for AWS apps on Fly.io. We fix AWS-specific deployment issues, configure Fly.io, and get your app live. From $19.
AWS issues we fix before deploying
Common AWS problems that affect Fly.io deployments.
Overly permissive IAM policies
AI-generated IAM policies using Action: '*' and Resource: '*' — granting full access to every AWS service. This is the cloud equivalent of leaving all your doors unlocked.
Public S3 buckets
S3 buckets configured with public access for convenience during development. User uploads, database backups, and configuration files become accessible to anyone on the internet.
Unencrypted data at rest
Databases (RDS, DynamoDB), S3 buckets, and EBS volumes without encryption enabled. If a backup is exposed, all your data is readable.
Security groups wide open
EC2 security groups allowing inbound traffic from 0.0.0.0/0 on all ports instead of restricting to specific ports and IP ranges.
Fly.io deployment issues we check for
Common Fly.io problems that break AWS apps in production.
Dockerfile missing or misconfigured
Fly.io requires a Dockerfile for deployment. AI tools that scaffold without one force flyctl to auto-generate a suboptimal Dockerfile that misses build steps.
Volume only available in a single region
Fly volumes are pinned to one region. Multi-region deployments try to access a volume that doesn't exist in other regions, causing crashes.
Machine restarts losing in-memory state
AI-generated apps store session data or caches in memory. Fly machines can restart or migrate, wiping all in-memory state without warning.
Internal DNS resolution failing between services
Services within a Fly organization communicate via <app>.internal hostnames, but AI-generated code hardcodes localhost or public URLs.

Frequently asked questions
How do I deploy a AWS app to Fly.io?
We handle AWS deployments to Fly.io end to end. Start with our code audit ($19) to identify deployment blockers specific to your AWS project, then we configure Fly.io, fix issues, and get your app live in production.
What AWS issues affect Fly.io deployments?
AWS projects commonly have overly permissive iam policies and public s3 buckets. On Fly.io, these combine with dockerfile missing or misconfigured and volume only available in a single region to cause deployment failures.
Can SpringCode deploy my AWS project to Fly.io?
Yes. We specialize in deploying AWS applications to Fly.io. We audit your codebase for AWS-specific issues, configure Fly.io correctly, and handle the full deployment so your app runs reliably in production.
What does AWS deployment to Fly.io cost?
Our code audit ($19) identifies all Fly.io deployment blockers in your AWS project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
