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.
