fly

You can deploy Fly.io apps using flyctl with rolling, immediate, bluegreen, or canary strategies to manage rollouts and inspect changes. These strategies ensure controlled deployments for both stateless and stateful services.

The best way to manage Fly.io secrets is to stage them first, then deploy in a controlled batch. You can audit completeness to catch missing variables and ensure synchronized secret updates across your application.

To enable TLS certificates for a custom domain on Fly.io, use flyctl to add certs, view and poll issuance status, and validate HTTPS readiness with a known endpoint, automating certificate provisioning for your application.

Yes, flyctl supports persistent storage and scaling for stateful services by provisioning volumes, managing snapshots for safer upgrades, and tuning auto-stop and auto-start settings for cost optimization across VM sizes and regions.

Yes, you can SSH into Fly.io Machines and stream logs for debugging. Flyctl provides operational tooling for logs, health checks, SSH access, and diagnostics to debug live Machines without building a custom platform.

You need private networking across Fly.io apps when productionizing stateless and stateful services that require controlled rollouts, persistent data, and certificate automation, enabling secure communication between your deployed applications.
