OBLB is a software load balancing tool that is based on iptables. You can configure OBLB for an OBProxy cluster to improve its load balancing capability.
- If the OBLB service is not configured for an OBProxy cluster, you can click Add Load Balancing to add the OBLB service for it.
- If the OBLB service is already configured for an OBProxy cluster, you can click Modify Load Balancing to update the related OBLB information.
