keepalived-2.1.5-8.el8.ML.1

The keepalived utility provides simple and robust facilities for load balancing
and high availability. The load balancing framework relies on the well-known and
widely used IP Virtual Server (IPVS) kernel module providing layer-4 (transport
layer) load balancing. Keepalived implements a set of checkers to dynamically
and adaptively maintain and manage a load balanced server pool according to the
health of the servers. Keepalived also implements the Virtual Router Redundancy
Protocol (VRRPv2) to achieve high availability with director failover.
