I'm tasked with implementing a 2 tier PKI (ADCS) with 2 subordinate CA's to provide high availabilty. Now I am wondering if I have 2 suborindates with the same certificate templates active, how will be determined what CA will handle requests. (No load balancers present)
Can I expect an even flow or will 1 CA be used most of the time?
The PKI will be built with Windows Server 2019
