About This Architecture

Ticketz is a serverless event ticketing platform on Azure combining WAF protection, API Management, and event-driven Functions to handle high-volume concurrent bookings. Users flow through Azure Front Door and Static Web App to API Management, which routes booking requests to Azure Functions that publish to Service Bus for asynchronous processing. Worker Functions consume queue messages, lock seats in Cosmos DB, generate QR code assets in Blob Storage, and retrieve secrets from Key Vault while Application Insights monitors all tiers. This architecture demonstrates virtual queueing and seat-locking patterns essential for preventing overselling during flash sales and high-demand events. Fork this diagram on Diagrams.so to customize resource names, add traffic policies, or extend with additional Functions for refunds and notifications. The event-driven design decouples booking requests from fulfillment, enabling independent scaling of API and worker tiers.

People also ask

How do you build a scalable event ticketing system on Azure that handles virtual queueing and prevents seat overselling?

Ticketz uses Azure Functions for stateless booking APIs, Azure Service Bus for async queue processing, and Cosmos DB with seat-locking logic to prevent overselling. Worker Functions consume queue messages, lock seats atomically, and generate QR codes in Blob Storage, while Application Insights monitors all tiers for performance and errors.
