Sending and Receiving Messages to an Azure Service Bus Topic

Azure Service Bus is a cloud-based Publish/Subscribe messaging service from Microsoft. Messaging has many use-cases, including:

• Decoupling applications to improve reliability and scalability
• Load balancing workloads so that costs can scale with usage
• Enabling transactional operations

Azure Service Bus is serverless and managed. When using it, you don't need to worry about storing logs, handling backups, patching servers, or failover strategies. All these things are taken care of for you by Microsoft Azure.

In this hands-on lab, you will create a simple web application in NodeJS that sends and receives messages to and from an Azure Service Bus topic.
