IQ Messenger cluster (also known as high availability or redundancy)
The IQ Messenger software runs within an High-Availability (HA) cluster environment on two different (virtual) servers. If there is a disruption of the server or one of the critical applications of the IQ Messenger software, the second server will take over the operation automatically.
When one or more of the critical services are failing on the first server, this server will attempt to autonomously restore the relevant processes. If this does not happen within a variable time, the second server will take over the sessions and act as the primary server. An alarm message is also send to a device or system of choice for notification.
A failover of the redundant server takes about 10 seconds. When medical devices have an alarm during the failover time, they are automatically placed in the alarm queue of the medical device itself or the current status of the medical device is updated. This logic therefore differs per medical device and no messages are lost as they will be resend by the medical device or retrieved by the IQ Messenger platform.
