You are planning the deployment of two Azure Stack Hub integrated systems that will be located in Seattle and Redmond, respectively.
Workloads will run on infrastructure as a service (IaaS) virtual machines that have a static IIS web front-end and a Microsoft SQL Server 2019 cluster backend for database storage.
You plan to leverage Azure Traffic Manager to direct DNS requests to the integrated system in Seattle by default and use the Redmond integrated system in the event of a disaster.
What should you use to replicate application consistent database changes to the Redmond site?
