In this lab, you will create, deploy, and configure an application using Java and the Azure Service Bus to demonstrate the use of messaging with queues. Your first exercise will be to create a development environment where you can create and debug Java code. After that, you will create a Service Bus queue, an Azure Function, and an Azure Cosmos DB database to demonstrate the full message cycle. The Java web application, running in Docker on your development machine, will use the Service Bus queue to communicate with the Azure function which will process the message and finally save the result into the Cosmos DB database.
In this exercise, you will install some Visual Studio Code extensions and load the Java project into the editor and check that your environment is configured properly.
