Hi community

My company plans to use FlowFuse for our product. The price of FlowFuse is based on the number of instances in use.

Currently, we are confusing how to estimate the number of instances with a certain workload. When  
we should create to use a new instance if the current instance’s CPU or Memory usage exceeds a threshold value, for instance.  
Does FlowFuse support any solution or is there any recommendation?

Thank you

Hi @pdt590 that is quite an open ended question that would require a fair bit more information to do it any real justice. I will tag @zackwasli who can arrange a chat to better understand your requirements.
