F5 Load Balancers

Added On	March 12, 2008

Load Balancers distribute incoming connections according to a variety of algorithms

NOTE: There is a maximum of 3 Load Balancers per account allowed. Any attempts to add more than three Load Balancers will fail. This is by design.

Load Balancer Type

Round Robin

Round Robin Load Balancing takes all incoming connections and routes them one at a time, server by server in an equally distributed fashion with each server taking turns. If you have two servers, incoming connections will alternate between the two. If you have 4 servers, connections will be routed to server 1, server 2, server 3 and then server 4 before beginning the cycle again.

Least Connect

Least Connect Load Balancing will route incoming connections to the server with the lowest load on it. Connections are sent to each server depending on the total number of concurrent sessions on the servers. If you have two servers, the first with 24 sessions running and the second with 12 sessions running, then incoming connections will be routed to server 2 until the ratio of connections changes.

Load Balancer Persistence

None

None is the default, determining routing only according to Load Balancer Type

SSL Sticky

SSL Sticky will route all traffic for an SSL session to the same destination after the initial connection establishes the session. Note that this persistence only works for SSL traffic and load balancing for other types of traffic will not work when this is set.

Source Address

Source Address persistence will cause all traffic from a given source address to be routed to the same destination host after the initial connection.
