How to configure Load Balancer for Crucible? Any documentation available on this?

Crucible can't be clustered, so what purpose would an LB serve?

[Chag]

you might be able to load balance at the network layer. Get a networking device that loads balance between the two websites but, you will have to find a way to have the DB's in sync and same data.

You need a Crucible license, for each instance of Crucible you have running.

As mentioned previously however, Crucible can not be clustered, so load balancing will not work.

If you are concerned about performance due to many concurrent users, or many 1000s of projects on a single instance, one semi-solution which some customers use is to split your single instance down into separate ones. These will have different URLs etc and different data, though can work fine if your organisation can be split up into smaller groups of projects.

Also note that Crucible does not yet support project migration between instances, so choose wisely how to split...

[Sergey Svishchev]

You can set up a cold standby instance and make sure your lb always gives priority to currently active one. As Jamie noted, actual load balancing is not possible.

Typical approach for better scaling. especially for enterprise level, we want go with multiple instances of crucible. and end user is exposed with load balancer host name. 

in this aspect, i am not sure how crucible instances will be able to share load to avoid performance issues. and how does licenses work?

I appreciate your help in this!!
