Event Hubs allow the processing of millions of data points for customer via the Microsoft Azure platform.
In order to receive schedules and/or status data changes and updates from Flight Info Alerts, we require customers' systems to connect to an Event Hub, which is a cloud-based service by Microsoft Azure.
A separate Event Hub is provisioned by OAG for every Flight Info Alerts subscription to handle and process flight changes and customers only need to create an event consumer to receive this data.
