Load Balancing Roundup
There’re lots of load balancing algorithms:
- Stupid L4 (round robin) - Slightly smarter L4 (least connection, weighted RR, etc) - L7, or inspection based load balancing. - Perlbal. Guess that’s also L7
In this session we’ll briefly go over each of the basic load balancing algorithms as they’re implemented in popular open source load balancers.
In a second half we’ll show some synthetic load testing situations to illustrate how traffic handles under the different algorithms.
Noticed your servers overloading all the time? Perhaps they’re idle 50% of the time? Want to minimize latency? You might want a thorough understanding of load balancing.
