fly.ioReviews of fly.io

We experienced zero friction migrating our containerized workloads over to Fly.io. It is refreshing to see an infrastructure provider that isn't just an API wrapper over AWS; they run hardware-virtualized KVM containers that spin up fast enough to handle incoming HTTP requests natively. The built-in private mesh networking works beautifully over WireGuard tunnels out of the box, completely eliminating the need for bloated Terraform configurations for intra-cluster auth. To be fair, their official documentation can be quite sparse and minimalist, occasionally forcing you to hunt through their community forums to resolve specific edge-case routing issues. However, their new Sprites sandboxing feature executes environment checkpointing in under a second, and the CLI-driven deployment is rock solid.
