# Sōzu

## What is Sōzu?

Sōzu is a reverse proxy for load balancing, written in Rust. Its main job is to balance inbound requests across two or more clusters backends to spread the load.

* It serves as a termination point for TLS sessions. So the workload of dealing with the encryption is offloaded from the backend.

* It can protect the backends by preventing direct access from the network.

* It returns some metrics related to the traffic between clients and backends clusters behind it.
