Hello @bchastanier,
Thanks for your answer.
I guess you mean why don’t I want to run c5a.xlarge for all?
Well I’m having another problem with the auto-scaling: Auto-scaling with multiple apps - #7 by Pierre_Gerbelot and because of that, it’s costing us a lot of money.
So as we are working on trying to fix the auto-scaling issue, I thought that having an issue with auto-scaling on t3.medium instances would cost less than an issue with c5a.xlarge nodes ^^
