title: How would I implement high availability across regions for Azure IOT hub?
body: <p>I'm looking into what our high availability options are for our IOT hubs on azure, specifically cross-region as discussed in this article:</p>
  <p><a href="https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-ha-dr" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-ha-dr</a></p>
  <p>Cross-region HA would give us the quickest RTO (recovery time objective) but I’m struggling to find pertinent tutorials, guidelines on implementation.</p>
  <p>So far I think these are our options:
  i)  Go down the route of using a mediator/listener in a load balanced configuration across regions
  ii) setup a secondary connection on the devices?</p>
  <p>Could anyone help with advising on a typical approach, possibly reference an article we can use as an example?</p>
