Answer

When using the Hub Gateway Add-on, high availability is important because if Hub is down when an external application sends a Gateway request, that request will be lost if the external application does not retry.

If you are concerned about the availability of your Hub server when using the Gateway Add-on, you can set up a high availability configuration with two identical instances of Hub fronted by a load balancer. For more details on this process, please contact customer care to access our Business Continuity & Disaster Recovery materials.
