|Deploying VMP / Vocera Messaging Platform Failover|
Use these steps to create a DNS round robin clustered VMP Server with a secondary IP address associated with the main server hostname.
A Load Balancer is used to redirect traffic to the node of the cluster that is currently active. The DNS entry or IP address of the Load Balancer serves as the point of contact for the outside world. If the primary VMP Server fails, the Load Balancer redirects traffic from the primary server to the secondary server.
In the event of a failover, the VMP services must be manually re-started for the application to function. The data exchange service is restarted on the secondary node.
