We have an existing three cluster (three server) site being run through a single web adapter that handles all of our web, mobile, image and geoprocessing services. Based on our experience in a test environment we found that adding GeoEvent to an existing ArcGIS for Server box caused performance issues so we had a new production server built to host it. My question to this group is do you need web adapter on an ArcGIS server site setup focused on GeoEvent Processor? How are other groups adding GeoEvent processor into their existing architectures? I haven't been able to find recommendations specific to this extension.
