Unravel deployment for high availability

The Unravel service can preserve business continuity after a disruptive event, for example, a node failure.

To preserve continuity, you must:

  • Run two Unravel servers in Active-Passive mode.

  • Have a load balancer fronting the network traffic from Unravel sensors, Users, and REST API calls.

  • Run Unravel’s data stores in the HA configuration.

Impact of the switch over from the failed to the passive server

  • During the brief time period traffic from Unravel sensors and REST API calls is lost.

  • User Sessions are not preserved.
