Redundant Ignition servers & OPC connections

Redundancy is always a challenge, especially in mission critical business. Just wondering, if it’s possible to combine the redundancy solution by other vendors with the redundancy by Ignition to build high availability SCADA systems.

I am particularly impressed with Stratus stratus.com/. Pls share your views.

Note:
I haven’t fully tested the ignition redundancy. I would love to know other people’s experience on this topic to build a robust solution on ignition. Thanks.
