The document discusses load balancing with Linux Virtual Server (LVS). It describes using LVS with keepalived for high availability across firewall, web, and application tiers. It provides details on Direct Routing configuration and monitoring options in keepalived like weight, connection counts, and packet rates. Real server configuration topics are also covered such as arp settings, iptables rul

Kernel Load-Balancing for Docker Containers Using IPVS
Yesterday at DockerCon Europe, Andrey Sibiryov, a senior engineer at Uber Technologies, demonstrated how to improve load-balancing performance using an open-source technology that’s been part of the Linux kernel for more than a decade — IPVS. What Is IPVS?To be precise, IPVS (IP Virtual Server) has been in the kernel for 15 years, and it’s based on netfilter. It supports TCP, SCTP, and UDP and can

3. LVS Performance and Kernel Tuning
(a non-LVS article on Configuring large scale unix clusters by Dan Kegel.) The article performance data for a single realserver LVS, shows how to test the network links with netpipe and how to determine the effects of LVS on latency and throughput. Note the effect of the LVS code on system performance is the difference between the performance with the director box just forwarding packets as a rout
