![Getting Started with Azure Functions](https://ajtatumdigital.com/wp-content/uploads/banners/getting-started-lightbulbs-1920-by-1080.jpg)

## **Getting Started with Azure Functions**

Now that you understand the benefits and use cases of Azure Functions in workflow automation, let’s dive into the process of getting started with Azure Functions. Here is a step-by-step guide to help you begin your journey:

### **Step 1: Set up an Azure Account**

To start using Azure Functions, you will need an Azure account. If you don’t have one already, you can sign up for a free Azure trial or explore the various subscription options available. Once you have your Azure account set up, you can proceed to the next step.

### **Step 2: Create an Azure Function App**

The next step is to create an Azure Function App, which will serve as the container for your functions. The Function App provides the runtime environment and resources required to execute your functions. You can create a Function App through the Azure portal or by using the Azure CLI, Azure PowerShell, or VS Code with the Azure extension.

![Azure Functions plus VS Code](https://ajtatumdigital.com/wp-content/uploads/banners/web-development/azure-functions-plus-vs-code.png)

I personally recommend installing VS Code and then the Azure extension. After installing the extension, you’ll be prompted to log into your Azure Account. Next, open a folder in VS Code for your project and then press the Ctrl, Shift, and P keys at the same time. In the dialog box, just begin typing Azure Functions, and you’ll see the option to create one.

### **Step 3: Develop your Azure Functions**

Once your Function App is set up, you can start developing your Azure Functions. Choose the language you are most comfortable with and begin writing the code for your functions.

Azure Functions support multiple languages, including C#, F#, JavaScript (Node.js), Java, PowerShell, Python, and TypeScript.

If you’re completely new to programming, I would highly recommend starting with JavaScript or Node.js. Not only is Node.js a powerful language, but you’ll also be learning JavaScript along the way, which can be used on the front-end and back-end of web and mobile applications.

For me, as a .NET/C# developer with over 15 years of experience, I tend to lean towards C# for most of my Azure Functions, and I encourage you to give it a try as Microsoft has done a fantastic job with documentation for you to get started.

However, I definitely believe that there are certain languages that are geared towards specific goals.

For example, if I’m doing something that involves parsing a website or HTML, using JavaScript is my go-to.

If I’m doing something that collects large amounts of data, Python tends to perform well.

### **Step 4: Configure Triggers and Bindings**

Azure Functions rely on triggers to determine when to execute the associated code.

Triggers can be configured to respond to various events, such as HTTP requests, timer schedules, or changes in data storage.

One of the most common triggers that I’ve used is utilizing Azure Storage. You can use Azure Storage Blobs, Queues, and Tables as triggers for an Azure Function.

Additionally, bindings can be used to connect your functions to external resources, such as databases or message queues.

There are a lot of options when it comes to binding to message queues, as Azure has a variety of options, and it can get confusing really quickly. I tend towards Azure Service Bus (you typically only need the basic plan) because it offers more control, is more resilient, and offers more flexibility.

Configure the appropriate triggers and bindings for your functions to ensure they are invoked and interact with the necessary resources.

### **Step 5: Test and Deploy your Functions**

Before deploying your functions to a production environment, it is crucial to thoroughly test them to ensure they function as expected.

If you’re developing your function in VS Code, you can easily test your function by going to the “Run” menu and selecting “Start Debugging”.

Before you start debugging, you may want to consider implementing breakpoints by going to the line of code and pressing the F9 key. Breakpoints allow you to see what a variable or function is doing while debugging, so if something goes wrong, you’ll know exactly where to look.

### **Step 6: Monitor and Scale your Functions**

After deploying your Azure Functions, it is essential to monitor their performance and usage.

Azure provides various monitoring tools and metrics that allow you to track the execution of your functions, identify potential bottlenecks, and optimize their performance. I recommend using Azure Application Insights with every function.

Additionally, take advantage of Azure’s auto-scaling capabilities to ensure your functions can handle increased workloads and maintain optimal performance during peak periods.
