I am wondering if it is possible to have two instances of the PI Web API running concurrently against a collective/single instance(s) of PI DA and PI AF?
This is in order to have a coresight server within an internal network to provide its functionality to intranet sites (with the Web API service running in support on the same server, which is done by default on installation of coresight), and to have an additional Web API within the DMZ to provide some access externally to the PI system. More than likely this would be GET/OPTIONS requests initially, with the intention to perform some POST/PUT requests on PI points/AF attributes.
I understand the security issues which will need to be addressed to lock this all down, however I am wondering form a purely Network/Architecture basis if this is possible?
Thanks in advance for any input,
