Continuous Availability for CAD Systems: Ambulance

Assuring CAD continuous availability for one of the world’s largest ambulance services

More people live in New South Wales than any other part of Australia, which leaves the state’s ambulance service with a very big job. In fact, the Ambulance Service of New South Wales (Ambulance) is the third largest in the world and responds to a request for assistance about every 28 seconds. That’s more than 1,133,000 emergency and non-emergency calls. Read on to learn why Ambulance chose Stratus continuous availability solutions to run their CAD systems.
