FAQPage Schema

How do I deploy an application to Fly.io edge infrastructure?▼

To deploy an application to Fly.io edge infrastructure, you use the flyctl CLI to launch your app, which provisions Firecracker micro-VMs close to users for low latency execution. You need a Dockerfile or app sources to deploy.

What is multi-region deployment on Fly.io?▼

Multi-region deployment on Fly.io runs your workloads across edge locations globally using Firecracker micro-VMs. This reduces latency and enables region-aware scaling for fast, responsive app launches across continents.

Do I need Docker to deploy apps on Fly.io?▼

Yes, you need a Dockerfile or app sources to deploy apps on Fly.io. The deployment process uses the flyctl CLI to package and run your application on Firecracker micro-VMs at edge locations.

How does Fly.io reduce latency for global applications?▼

Fly.io reduces latency by running workloads on edge infrastructure using Firecracker micro-VMs, which places execution near users. This enables near-user execution and fast, responsive app launches across multiple regions.

Can I scale my app across multiple regions with Fly.io?▼

Yes, you can scale your app across multiple regions with Fly.io. The platform supports multi-region deployment and region-aware scaling to maintain low latency for users across different continents.

What is the best way to launch an app on Fly.io edge?▼

The best way to launch an app on Fly.io edge is to install the flyctl CLI, log in, and run the launch command. This streamlines the workflow to provision Firecracker micro-VMs for near-user execution.
