Octavia is the OpenStack Load Balancer as a Service (LBaaS) version 2 implementation for the Red Hat OpenStack Platform . It accomplishes its delivery of load balancing services by managing a fleet of virtual machines, collectively known as amphorae, which it spins up on demand.
Load balancing methods -
- Round robin - Rotates requests evenly between multiple instances.
- Source IP - Requests from a unique source IP address are consistently directed to the same instance.
- Least connections - Allocates requests to the instance with the least number of active connections.
