The main goal of this project is +to provide simple and robust facilities for loadbalancing and high-availability +to Linux system and Linux based infrastructures. Loadbalancing framework relies +on well-known and widely used Linux Virtual Server (IPVS) kernel module +providing Layer4 loadbalancing. Keepalived implements a set of checkers to +dynamically and adaptively maintain and manage loadbalanced server pool +according their health. On the other hand 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. + +Usage +----- + +Once ready, deploy as follows: + + juju deploy keepalived + juju add-relation haproxy keepalived + |
