Fly.io
Fly.io is a cloud application hosting platform for developers that runs application containers using microVM technology and supports distributed deployment across multiple global edge nodes. The platform allows users to deploy applications via a command-line tool to data centers closest to end users, reducing network latency. It supports multiple programming languages and frameworks and is suitable for hosting web applications, API services, and databases.
Timeline (last 90 days)
Modern hosting platforms such as Vercel, Railway, and Fly.io have lowered the operational barrier for AI Agent deployment.
Firecracker microVMs are used by AWS Lambda and Fly.io.
Fly.io provides two types of deployment credentials: account-level API tokens and app-scoped deploy tokens.
Fly.io app-scoped deploy tokens can be generated using the command fly tokens create deploy -a <app-name>.
Fly.io Volumes are NVMe-based persistent block storage where data is retained across app restarts or redeployments.
Previously, datasette-publish-fly may not have worked correctly with app-scoped tokens because certain operations required account-level permissions.
In CI/CD environments, it is recommended to use app-scoped deploy tokens to follow the principle of least privilege and limit the attack surface in the event of token leakage.
Common measures to alleviate the difficulty of sudden server scaling include using managed platforms with automatic elastic scaling such as Railway, Fly.io, and Render, introducing message queues to decouple high-concurrency writes, and setting reasonable concurrency limits for WebSocket connections with graceful degradation handling.
Fly.io 和 Railway 对小型多容器项目友好，提供免费额度，冷启动体验优于手动开关虚拟机
对于几乎无流量的展示项目，可采用分层部署：核心模型服务部署到低成本常驻服务，监控组件（Prometheus/Grafana/MLflow）按需拉起
