Azure Service Bus is the planet's most powerful hyperscale PaaS message queuing platform.

Your airport check-in, settling the bill for your online purchase, the package delivery at your doorstep, and unlocking your vehicle with a mobile app may all run through Azure Service Bus. In this session we will pull away the curtain and give you a deep-dive look at how Service Bus is built and run.
