We have deployed a 2-server ArcGIS Server instance using ESRI ArcGIS Enterprise Cloud Builder 10.8.1 for Microsoft Azure.
In the event of a regional DR scenario what can be done to expedite recovery and/or are there certain items such as configuration of map services that must be re-configured regardless of whether or not we have things replicated to a secondary region?
For example - if there was an outage in Azure US-EAST region for any reason, would pointing resources to a replicated instance in US-CENTRAL cause issues with ESRI map services or would they still run without re-deploying them?
Any documentation or insights into replication of resources or disaster recovery scenarios would be greatly appreciated.
Are you familiar with the WebGIS DR tool? The tool, included with the install of Portal, is designed to help you maintain a "warm standby" by replicating content to a separate deployment in a different region on a scheduled interval. If there are issues with your primary environment, you can flip over to standby.
