In the previous article we looked at what’s the use LVS, to have a system of load balancing built into the Linux kernel. As mentioned, however, LVS was born to be good in one thing: the load balance, but does not provide additional options, such as monitoring the progress of the machines on which we are balancing service and in case of trouble in one machine remove it from the active machines.
To accomplish this goal and many more wel” take a look at ldirectord
Linux Virtual Server, LVS is an advanced load balancing solution for Linux systems. It is an open source project started by Wensong Zhang in May 1998. The mission of the project is to build a high-performance and highly available server for Linux using clustering technology, which provides good scalability, reliability and serviceability.
The major work of the LVS project is now to develop advanced IP load balancing software (IPVS), application-level load balancing software (KTCPVS), and cluster management components.
