Load-Balancing-as-a-Service (LBaaS) enables Neutron, the networking component of OpenStack, to distribute incoming requests among designated instances. This distribution ensures that the workload is shared predictably among instances and enables more effective use of system resources. Because LBaaS supports proprietary and open source load balancing technologies, OpenStack administrators have more options when choosing which back-end technology to use for load balancing.

The current OpenStack release supports LBaaS v1 and LBaaS v2. VMware Integrated OpenStack enables LBaaS v1 automatically. Optionally, you can manually enable LBaaS v2 in the VMware Integrated OpenStack CLI.
