If a study requires real-time monitoring, a new message is created from each result posting to the investigator’s institutional REDCap installation. The destination for this message is Azure Event Hubs. Event Hubs is a fully managed, real-time data ingestion service. Engineers at Microsoft ensure highly reliable endpoints with the potential for scale to millions of events per second. Our platform leverages Event Hubs to ensure captured data is successfully delivered from the iOS device, and available to our analysis and reporting applications at all times. With a dedicated service for receiving data with considerable variation in demand, requirements for downstream applications are automatically decreased to a great degree. Event Hubs also provides additional security from the standpoint that through subscriptions, data posted there is pulled into our application rather than pushed, and through schemas, only messages matching our criteria are ever seen. Event Hubs serves as the “front-end” of presents/with.
