Load-Balancer-as-a-Service (LBaaS)

Understand the following characteristics of the OpenStack-Ansible LBaaS technical preview:

  • The preview release is not intended to provide highly scalable or highly available load balancing services.
  • Testing and recommended usage is limited to 10 members in a pool and no more than 20 pools.
  • Virtual load balancers deployed as part of the LBaaS service are not monitored for availability or performance.
  • OpenStack-Ansible enables LBaaS v2 with the default HAProxy-based agent.
  • The Octavia agent is not supported.
  • Integration with physical load balancer devices is not supported.
  • Customers can use API or CLI LBaaS interfaces.
  • The Dashboard offers a panel for creating and managing LBaaS load balancers, listeners, pools, members, and health checks.
  • SDN integration is not supported.

Since Mitaka, you can enable Dashboard (horizon) panels for LBaaS. Additionally, a deployer can specify a list of servers behind a listener and reuse that list for another listener. This feature, called shared pools, only applies to customers that have a large number of listeners (ports) behind a load balancer.
