• Microservice hosting API endpoints that handle sign-up requests enable the creation and editing of user and company details. Requests are stored in Kafka and processed by a background consumer service. An IdentityServer on the MSSQL database handles user account creation and setup, atomically writing data to multiple tables within a transaction.
• An event-driven architecture, powered by a set of producer and consumer background services, processes 500,000 change events per day for core models. Producers listen to MongoDB change streams for event triggers, inserting them into Kafka. Consumers then handle these events, managing potential race conditions when multiple services access the same document. Data updates are written to several MongoDB collections concurrently within a transaction for data consistency.
