Active/Active DC design considerations - Without DNS
We're going through a DC migration at the moment and just in the high level planning stages.
Here's our question:
We can failover a DC or run them active/active using GTMs for Internet facing traffic.
However we have some larger clients who use our private MPLS for dedicated and secure access to our products.
These customers do not use DNS on the WAN, they target an IP (albeit with a hostname or using their local DNS servers)
Running DNS on the WAN is not feasible.
What options are available to provide site resiliency with GTM/LTM when DNS is not available?
