This article describes how to use clustering with Airlock to provide failover capability and load balancing. This may be realized with Airlock own functions or with dedicated load balancers in front of or behind Airlock.
Two Airlocks together may be operated as a failover cluster. If so, one Airlock is active, receives data and is monitored by the passive one. If the passive Airlock detects an error on the active one, it takes over automatically. The monitoring is done on a separate channel by using the cluster talk protocol.
For loads that cannot be managed with one single hardware anymore, Airlock supports upstream load balancing.
This kind of scenery is recommended only for testing and integration environment.
The following list shows the major positive and negative aspects.
This kind of scenery is used most for productive Airlock environments.The following list shows the major attributes of a failover cluster Airlock system.
This kind of scenery is used for high performance and high redundant system requirements.The following list shows the major attributes of a load balanced Airlock farm.
