Enhance Linux Virtual Server with a reliable keepalive feature for uninterrupted and efficient connectivity.
When one of the servers in an LVS server pool goes down, Keepalived informs the Linux kernel through a setsockopt call. This results in the removal of the server entry from the LVS topology. Additionally, Keepalived also implements an independent VRRPv2 stack to handle director failover.
Overall, Keepalived is a userspace daemon that offers robust health checks for LVS cluster nodes and LVS directors failover. If you are using a LVS director to loadbalance a server pool in a production environment, Keepalived is the tool you need to ensure a stable and reliable solution for health check and failover.
