  • With ASR you will create a Failover Plan, steps to be conducted during failover. When you decide to failover your infra, only one button will be hited.

    I understand what is your concern. You want that somehow, a mechanism will detect failure and kick off the failover process. But this is not as easy as you think, Why? Because till today, there is no Artificial Intelligence that can think and take such difficult decision. Don't you realize that failing over a production infrastructure will have consequences ?? 

    All you workloads will be in Azure, network degradation, downtime, dns changing, new experience and a lot of consequences that imho, will be an Enterprise decision.

    What if for some reason, a power outage happens in your Datacenter, and that Automatic Failover procedure starts after 15 minutes of downtime. What if you knew that this just a button in your powersupply that you have to hit, And that the person will need 16 minutes to be there !

    The real life is : someone needs to evaluate the situation and than make a decision. The decision is to click the Failover button an Azure, and Azure will do everything for you

  • Hi GpC72,

    There is no automatic failover built in the portal. However, you can use the powershell SDK to trigger a failover. You can use the on-premises Orchestrator or SCOM to witness a VM failure and decide to trigger the failover using the SDK. This will make it automatic.

    Hope that helps.

    Thank you,

  • We don't have provision for automatic procedure. ASR solution is automated DR where with one click we are able to bring up VM's, multi-tier applications .
