• How many client controllers does CJOC able to accommodate?
• Is there any limitation on the number of client controllers connected to a single CJOC?

Resolution

There is no technical limit on the number of Client controllers that the CJOC can accommodate. It is rare for customers to have more than 100 controllers connected, and this still does not present any issues. If you are planning to have a larger number connected, we would want to work with you to make sure your CJOC was configured correctly and has enough system resources available. Depending on the terms of your license, you may be limited in the number of controllers you can attach. If you aren’t sure of the limits of your license, you would need to clarify that with your CloudBees Customer Success Manager.
