Outline:
Azure Function | Service Bus Queue Trigger | Session Enabled
Introduction
Azure Function is an event-driven, serverless computing platform used to build serverless applications. It gives you the capability to run code without having to manage the infrastructure. Service Bus Queue Trigger is an Azure Function binding that allows you to trigger a function when a message arrives in a Service Bus Queue. Session Enabled allows for messages to be processed in order, meaning that messages sent to a queue in a particular order will be processed in the same order. In this blog post, we’ll discuss the details of Azure Function | Service Bus Queue Trigger | Session Enabled and provide a step-by-step guide for creating a serverless application with this setup.
What is Azure Function?
Azure Function is a serverless computing platform used to build serverless applications. It is an event-driven, pay-per-use computing service that enables developers to quickly create and deploy small pieces of code, known as functions, without having to manage the underlying infrastructure. Azure Functions can be triggered by a variety of events, including timer triggers, webhooks, and changes in data stored in Azure Storage.
What is Service Bus Queue Trigger?
Service Bus Queue Trigger is an Azure Function binding that allows you to trigger a function when a message arrives in a Service Bus Queue. When a message arrives in the queue, the function is triggered, and the function’s logic is executed.
What is Session Enabled?
Session Enabled is a feature of Service Bus Queue Trigger that allows for messages to be processed in order. When this feature is enabled, messages sent to a queue in a particular order will be processed in the same order. This ensures that the messages are processed in the order that they were added to the queue.
Step-by-Step Guide
1. Create an Azure Function App
The first step in creating a serverless application with this setup is to create an Azure Function App. This can be done by logging into the Azure Portal and navigating to the “Function Apps” section. Once there, you will be able to select the “Create Function App” option. You will then be guided through a series of steps to create your function app, including selecting the subscription, resource group, storage account, and region.
2. Add a Service Bus Queue Trigger
The next step is to add a Service Bus Queue Trigger to your Function App. This can be done by navigating to the “Triggers” tab in the Function App’s settings and selecting the “Add” option. You will then be prompted to enter the queue name and the connection string for the queue.
Once the queue is created, you will need to select the “Session Enabled” checkbox to enable the feature. This will ensure that messages sent to the queue in a particular order are processed in the same order.
3. Create a Function
The next step is to create a function in your Function App. This can be done by navigating to the “Functions” tab and selecting the “Create Function” option. You will then be prompted to select the language and template for the function. For this setup, we will be using C# and the Service Bus Queue Trigger template.
Once the function is created, you will need to add the code to define the logic for the function. This code should include instructions for how to process the messages arriving in the queue.
4. Deploy the Function App
The final step is to deploy the Function App. This can be done by selecting the “Deploy” option in the Function App’s settings. This will deploy the Function App and make it available to be triggered by messages arriving in the queue.
Conclusion
Azure Function | Service Bus Queue Trigger | Session Enabled is a powerful combination of features that can be used to create a serverless application. By following the steps outlined in this blog post, you can quickly create a serverless application that can process messages sent to a Service Bus Queue in a particular order.
