These machines are designed to boot quickly, in around 300ms, making them ideal for responding to HTTP requests. Users can also clone these machines to deploy their applications in any region served by Fly.io.

In addition to its core services, Fly.io also offers a range of additional features, including globally distributed databases, fast nVME storage, and Postgres cluster management. These features are designed to help users manage their applications more effectively and efficiently. Fly.io makes money by charging users for the resources they use. This includes the number of Fly Machines they run, the amount of storage they use, and the amount of data they transfer.
