In Conclusion

You don't have to understand exactly how the LVS code hooks into the Linux kernel to build a cluster load balancer, but in this chapter I've provided you with a look behind the scenes at what is going on inside of the Director so you'll know at what points you can alter the fate of a packet as it passes through the Director. To balance the load of incoming requests across the cluster using an LVS Director, however, you will need to understand how LVS implements persistence and when to use it, and when not to use it.
