High Availability monitor built upon LVS, VRRP and service pollers
Keepalived provides simple and robust facilities for load balancing
and high availability to Linux system and Linux based infrastructures.
The load balancing framework relies on well-known and widely used
Linux Virtual Server (IPVS) kernel module providing Layer4 load
balancing. Keepalived implements a set of checkers to dynamically and
adaptively maintain and manage load-balanced server pool according
their health. High availability is achieved by VRRP protocol. VRRP is
a fundamental brick for router failover. In addition, keepalived
implements a set of hooks to the VRRP finite state machine providing
low-level and high-speed protocol interactions. Keepalived frameworks
can be used independently or all together to provide resilient
infrastructures.
