This segment presents common needs for East-West load balancing in the datacenter and three approaches to addressing them, including software-defined networks.
- [Narrator] We've looked at two different reasons…to load balance traffic in and out of our data center,…and besides fault tolerance benefits,…the potential scale of this north/south traffic…can require some distribution of the load…to balance it out.…But I wanted to take a moment…to mention load balancing of network traffic…within the data center.…This traffic, from server to server…or from virtual machine to virtual machine,…is called east/west traffic,…and it has some different load balancing needs.…
Some data center administrators consider the need…for east/west load balancing to be a design flaw…in the topology.…That servers that need to communicate with each other…should be placed in proximity…so that they have the most direct connection possible,…and while that is definitely one approach,…sometimes more flexibility is needed.…The concept of clusters and virtual IP addresses…can still be used, but passing network traffic…through any kind of MUX or load balancer…can create a bottleneck.…
Most hardware load balancing solutions…
