I'm looking for some input to properly set up a failover system.

• Each DMA has been configured for HTTPS
• A wildcard certificate (eg *.dataminer.company.com) - issued by a trusted certificate authority - has been installed on each DMA
• In IIS, the certificate has a binding to the FQDN of the DMA (which matches with the wildcard certificate (eg dma01m.dataminer.company.com)
• In IIS, HTTP traffic is configured to be automatically redirected to HTTPS

This all works fine. We can reach all main/backup DMA's over HTTPS, and the certificate is correctly validated.

I was wondering what steps need to be taken in case we want to set up a 'virtual' FQDN for such failover pair?

Imagine that we have dma01m and dma01b configured as failover pair, and we'd like to use dma01.dataminer.company.com to access the online agent, in a similar way as a regular virtual IP would.

How could this be achieved?

Thanks!
