2 GTM across different Data Centers

Hi,

 

We are planning to deploy twin DCs and we want to have 1 GTM at DC-A and 1 GTM at DC-B. GTM will act as a DC selector through DNS.

 

I would like to know what will happen if we synchronize them? they will act in an active/passive fashion or in an active/active way, so both GTM will reply to DNS requests?

 

Thank you very much.

 

Best Regards,

 

JJBN

    They would both be active and will be configured as NS records in the zone, but they will work as a synchronised pair in that they will agree which device will monitor which objects and exchange configuration and state information.

     

    To answer your question directly, they will act as active/active and both reply to DNS requests in the same manner.
