This project provides facilities for load balancing and high-availability to
Linux system and Linux-based infrastructures. The load-balancing framework
relies on the Linux Virtual Server (IPVS) kernel module providing Layer4 load
balancing. Keepalived implements a set of checkers to dynamically and
adaptively maintain and manage loadbalanced server pool according their health.
High-availability is achieved by the VRRP protocol, 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.
