Fly.io
A platform that deploys applications close to users globally by wrapping Docker containers in secure, lightweight microVMs for extreme performance.
What it is
Fly.io transforms standard Docker containers into fast-booting Firecracker microVMs and deploys them across a global network of physical servers. It uses Anycast networking to route users to the geographically closest server, making it ideal for low-latency full-stack edge applications and distributed SQLite databases.
When you would use it
You deploy to Fly.io when your application demands low-latency global distribution, or when you need the simplicity of a PaaS combined with the control of raw virtual machines.
Common operations
- Deploying a highly responsive, globally distributed Remix application.
- Running persistent stateful databases at the edge close to end-users.
