I currently am running R shiny apps using shinyapps.io under the basic plan. A basic plan is allowed up to 3 instances and I have two questions:
Will each instance be allowed 8gb of RAM or is the memory shared amongst the 3 instances?
How can a second instance be initiated? I am unable to start a second instance despite having the basic plan. In the simplest scenario where I've tried to force multiple instances, I have set the following parameters:
Max worker processes: 2
Max connections: 1
Instance load factor: 100%
The app works fine with two users but a third user (or more) gets a 503 error. This suggests to me that another instance is not firing up even though I would expect it to. It cannot handle a 3rd user, whether the memory usage is low or high, I've tried both.
Any help with these questions would be greatly appreciated!
