- Fly.io’s region coverage. Three regions, named above; nothing else is claimed.
- Cross-host private networking between services. Same-host private networking works today.
When to choose each
- Choose Fly.io if you need its region footprint or you already run your networking around it.
- Choose MIOSA if your product also needs sandboxes and agent workloads, a console for customers of your own, or one platform for machines, services and data.
