Thank you for the request and for calling out the availability considerations. We understand that High Availability is an important requirement in many environments.
Threat Manager’s current on-prem architecture does not easily support native clustering or built-in HA. Rather than introducing that capability into the existing design, our focus is on delivering resiliency and High Availability as foundational elements in our next-generation platforms.
For customers where uptime is a critical requirement today, we recommend implementing infrastructure-level safeguards such as VM redundancy, as well as defined backup and recovery procedures.
We use a product called Zerto to fail over both our NTM and NTP consoles in the event of a failure and we have our SQL backend configured as a two node cluster. Zerto is able to fail the server to another VM, in our case, in a different data center and is able to manipulate DNS so even if the IP changes, the DNS name will still point to the console.
