Introduction

Fly.io provides a platform for deploying and running containerized applications and databases globally, positioning them physically closer to end-users for reduced latency. It abstracts away complex infrastructure management, allowing developers to focus on application logic while leveraging a distributed edge network for high-performance web services and data access. The platform facilitates the operational aspects of maintaining a globally distributed application fleet, from initial deployment to ongoing scaling and monitoring, primarily through a command-line interface complemented by a web-based management console.
