Load balancing

First introduced in the Grizzly release of OpenStack, Load Balancing as a Service (LBaaS v2) provides users with the ability to distribute client requests across multiple instances or servers. Users can create monitors, set connection limits, and apply persistence profiles to traffic traversing a virtual load balancer. OpenStack Networking is equipped with a plugin for LBaaS v2 that utilizes HAProxy in the open source reference implementation, but plugins are available that manage virtual and physical load-balancing appliances from third-party network vendors.

More information on the use of load balancers within Neutron can be found in Chapter 13, Load Balancing Traffic to Instances.
