Synapse is a daemon used to dynamically configure and manage local instances of HAProxy as well as local files in reaction to changes in a service registry such as zookeeper. Synapse is half of SmartStack, and is designed to be operated along with Nerve or another system that registers services such as Aurora.

Nerve is a service registration daemon. It performs health checks on your service and then publishes success or failure into one of several registries (currently, zookeeper or etcd).
