Fly.io

Fly.io transforms containers into Firecracker MicroVMs running on bare metal across the globe. It is essentially a "CDN for your backend".

When to Use

• Global/Edge: You want your Node.js server running in Tokyo, London, and New York simultaneously.
• Postgres: Run a Postgres read-replica cluster globally with ease.
• Docker: You have a Dockerfile and want it running in 5 seconds.

Quick Start

fly launch
# Scans source code, creates Dockerfile, creates fly.toml

fly deploy
