libra-pool-mgm- A node pool manager to keep a warm spare pool of load balancers readylibra-worker- A node worker to asynchronously communicate to the API serverlibra-api- A customer API serverlibra-admin-api- An administrative API server
The API server is based on a modified version of the Atlas API specification.
High level overview
Here you can see that the pool manager spins up the required Nova nodes with the load balancer image. It then hands the details of these nodes over to the Admin API server.
The client sends an API request to the API server, which in turn sends the configuration information to the worker on the load balancer node. The worker has a plugin system to speak to multiple load balancer types but is currently designed to use HAProxy.
The statsd monitoring system routinely probes the workers and can alert on as well as disable faulty nodes.
