Sōzu

Open source HTTP reverse proxy built in Rust for immutable infrastructures. Most existing tools have a static vision of production: a service is installed once on a long-lived server, updated from time to time, with configuration rarely changing. There's now a shift in infrastructure to short-lived virtual machines and hundreds of new deployments per day, and the usual tools reach their limits. How do we reconcile a dynamic environment with availability guarantees? How can we get "zero downtime" deployments for critical services? SŌZU is a HTTP reverse proxy built in Rust, that can handle fine-grained configuration changes at runtime without reloads, and is designed to never ever stop. SŌZU receives and handles configuration changes at runtime and updates its internal configuration without restarts. You can update the configuration multiple times per second, and it will take care of lingering connections.
