Extra info and code examples

Openstack Load Balancer as a Service, codenamed Octavia was borne out of the Neutron LBaaS project. Its conception influenced the transformation of the Neutron LBaaS project, as Neutron LBaaS moved from version 1 to version 2. Starting with the Liberty release of OpenStack, Octavia has become the reference implementation for Neutron LBaaS version 2. Octavia accomplishes its delivery of load balancing services by managing a fleet of virtual machines, containers, or bare metal servers—collectively known as amphorae— which it spins up on demand. This on-demand, horizontal scaling feature differentiates Octavia from other load balancing solutions, thereby making Octavia truly suited “for the cloud.”. This package contains the Python files and libraries.
