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.
