Has anybody setup a PI system in the cloud where you have a collective already existing on-prem but would like to add a server to the collective in azure? We are looking to setup another server for fail over that would be part of that collective.
In theory that could work. I run my Dev system on Azure virtual machines and have no issues. If i understand correctly, you want to add a secondary PI server in the collective that is on Azure while the primary in on-premise? I'm not sure if the networing part will work due to the loadbalancer used by every VM in Azure. Read some details here: KB01418 - PI AF Client Connection Issues to PI AF Server Hosted in Microsoft Azure
A Collective with a member in the cloud has been done at least once before.
Depending on the version you use, you may have a difficult time with the Collecive creation process. Collective Manager makes heavy use of domain resources to authenticate to the secondary during the creation of a collective. There have been a few fixes in PI Server 2016 that would make this work better than it did in older versions. I assume your could VM will not be in the same domain as the primary. In the worst case, it could force you to do a manual setup of the collective.
Please report back if you do it!
