Azure for Beginners: Build Your First App Today

Want to understand Azure technology but don’t know where to start? It can seem daunting, but breaking it down into manageable steps makes it approachable, even for complete beginners. Ready to build your first cloud application? Let’s get started.

1. Setting Up Your Azure Account

First, you’ll need an Azure account. You can sign up for a free trial, which gives you a certain amount of credits to use within the first 30 days. After that, you’ll need to switch to a pay-as-you-go subscription, which means you only pay for the resources you use. I recommend using a separate email address for your Azure account, especially if you’re using it for learning and experimentation. This helps keep things organized and avoids accidental charges on your primary account.

Pro Tip: Don’t forget to set up multi-factor authentication (MFA) on your account! It’s an extra layer of security that protects your resources from unauthorized access. You can find the MFA settings in the Azure Active Directory section of the portal.

2. Navigating the Azure Portal

The Azure portal is your central hub for managing everything in Azure. Think of it as the control panel for your cloud environment. On the left side, you’ll find a navigation menu with various services like Virtual Machines, App Services, and Databases. The search bar at the top is your best friend; use it to quickly find the service you’re looking for. For example, type “Virtual Machines” to jump directly to the Virtual Machines creation page. I had a client last year who spent hours clicking through menus trying to find a specific setting, only to realize they could have just used the search bar!

Common Mistake: Overlooking the Azure Resource Manager (ARM) templates. These templates allow you to automate the deployment of resources in a repeatable and consistent manner. Learn ARM templates early on – they will save you a ton of time.

3. Creating Your First Virtual Machine

Let’s create a simple Virtual Machine (VM). Go to the Azure portal and search for “Virtual Machines.” Click “Create” and then “Azure virtual machine.” You’ll be prompted to fill out a form. Choose a resource group (or create a new one – resource groups are logical containers for your resources). Give your VM a name (e.g., “myFirstVM”). Select a region close to you – for instance, “East US” if you’re on the East Coast, or “West Europe” if you’re in London. Choose an image (e.g., “Ubuntu Server 22.04 LTS”). Select a size (the “Standard_B1ls” is a good starting point for testing). Set a username and password (or use SSH keys, which are more secure). Finally, configure inbound port rules, allowing at least port 22 for SSH access if you chose a Linux image. Click “Review + create” and then “Create” to deploy your VM. This typically takes a few minutes.

Pro Tip: When choosing a VM size, consider the workload you’ll be running. For development and testing, smaller sizes are usually sufficient. For production environments, you’ll need to choose a size that meets your performance requirements.

4. Connecting to Your Virtual Machine

Once your VM is deployed, you’ll need to connect to it. Find your VM in the Azure portal. Look for the “Public IP address.” This is the address you’ll use to connect. If you chose a Linux image, you can use SSH to connect from your terminal. Open your terminal and type: ssh username@your_public_ip_address. Replace “username” with the username you set during VM creation and “your_public_ip_address” with the actual IP address. You’ll be prompted for your password. Enter it, and you should be logged in.

Common Mistake: Forgetting to open the necessary ports in the network security group (NSG) associated with your VM. If you can’t connect, double-check that the NSG allows traffic on the port you’re using (e.g., port 22 for SSH, port 80 for HTTP, port 443 for HTTPS). You can find the NSG settings in the Azure portal under the “Networking” section of your VM.

5. Deploying a Simple Web App with Azure App Service

Azure App Service is a platform for hosting web applications, REST APIs, and mobile back ends. It supports various programming languages and frameworks, including .NET, Java, Python, Node.js, and PHP. It handles the infrastructure management for you, so you can focus on writing code. To deploy a simple web app, search for “App Services” in the Azure portal and click “Create.” Choose a resource group, give your app service a name (e.g., “myWebApp2026”), select a runtime stack (e.g., “.NET 8”), and choose a pricing plan (the “Free” plan is sufficient for testing). Click “Review + create” and then “Create.” Once deployed, you can deploy your code using various methods, such as FTP, Git, or the Azure CLI. For example, you can deploy a simple HTML file by uploading it via FTP using the deployment credentials provided in the App Service overview.

Pro Tip: Use deployment slots for staging and testing changes before deploying them to your production environment. Deployment slots allow you to create separate environments within your App Service, so you can test new features without affecting your live site. You can find the deployment slots feature in the Azure portal under the “Deployment slots” section of your App Service.

6. Working with Azure Storage

Azure Storage provides scalable and durable storage for various types of data, including blobs, files, queues, and tables. To create a storage account, search for “Storage accounts” in the Azure portal and click “Create.” Choose a resource group, give your storage account a name (e.g., “myStorageAccount2026”), select a location, and choose a performance tier (the “Standard” tier is suitable for most use cases). Click “Review + create” and then “Create.” Once deployed, you can upload and download data using the Azure portal, the Azure CLI, or the Azure Storage SDKs. For example, you can create a blob container and upload a file to it using the Azure portal. This is incredibly useful for storing static website assets, images, videos, and other types of unstructured data. We ran into this exact issue at my previous firm when migrating a legacy application to the cloud, and Azure Storage was the perfect solution.

Common Mistake: Not properly securing your storage account. Make sure to configure access keys, shared access signatures (SAS), or Azure Active Directory (Azure AD) authentication to protect your data from unauthorized access. You can find the security settings in the Azure portal under the “Configuration” section of your storage account.

7. Understanding Azure Networking

Azure Networking provides various networking capabilities, including virtual networks, subnets, network security groups, and load balancers. A virtual network (VNet) is a logically isolated network in Azure that allows you to connect your resources together. You can create a VNet by searching for “Virtual networks” in the Azure portal and clicking “Create.” Choose a resource group, give your VNet a name (e.g., “myVNet2026”), and specify an address space (e.g., “10.0.0.0/16”). You can then create subnets within your VNet to further segment your network. Network security groups (NSGs) are used to control inbound and outbound traffic to your resources. Load balancers distribute traffic across multiple VMs to improve performance and availability.

Pro Tip: Use Azure Network Watcher to monitor and diagnose network issues. Network Watcher provides various tools for troubleshooting network connectivity, including packet capture, connection troubleshooting, and network performance monitoring. You can access Network Watcher in the Azure portal by searching for “Network Watcher.” It’s better than guessing, wouldn’t you agree?

8. Working with Azure Databases

Azure offers a variety of database services, including Azure SQL Database, Azure Cosmos DB, and Azure Database for PostgreSQL. Azure SQL Database is a fully managed relational database service based on the SQL Server engine. Azure Cosmos DB is a globally distributed, multi-model database service that supports various data models, including document, graph, and key-value. To create an Azure SQL Database, search for “SQL databases” in the Azure portal and click “Create.” Choose a resource group, give your database a name (e.g., “myDatabase2026”), select a server (or create a new one), and choose a pricing tier. Click “Review + create” and then “Create.” Once deployed, you can connect to your database using SQL Server Management Studio (SSMS) or other SQL clients. Remember to configure firewall rules to allow access from your client machine.

Common Mistake: Not backing up your databases regularly. Azure SQL Database offers automated backups, but you should also consider implementing your own backup strategy to ensure data durability and availability. You can configure backup settings in the Azure portal under the “Backups” section of your SQL database.

9. Azure Resource Groups: The Foundation

Resource groups are logical containers for your Azure resources. They allow you to manage related resources as a single unit. When you create a resource, you must assign it to a resource group. This makes it easy to deploy, manage, and delete resources together. For example, you can create a resource group for a specific application or project. When you’re finished with the application, you can simply delete the resource group to remove all the associated resources. This helps prevent resource sprawl and makes it easier to manage your Azure environment. I’ve found that properly organizing resource groups from the beginning saves a lot of headaches down the line.

Pro Tip: Use naming conventions for your resource groups to make them easier to identify and manage. For example, you can use a prefix that indicates the environment (e.g., “dev-“, “test-“, “prod-“) followed by a descriptive name. For example, “prod-webapp-rg” for the resource group containing the production web app resources.

10. Case Study: Migrating a Small Business to Azure

Last year, we helped “Bob’s Burgers,” a fictional burger joint located near the intersection of North Druid Hills Road and Clairmont Road in Decatur, Georgia, migrate their legacy on-premises system to Azure. Bob had been using an aging server in the back office to manage orders, inventory, and customer data. The server was unreliable and difficult to maintain. We proposed migrating their application to Azure App Service, their database to Azure SQL Database, and their file storage to Azure Blob Storage. Here’s the breakdown:

• Timeline: The entire migration took approximately 4 weeks.
• Tools Used: Azure App Service, Azure SQL Database, Azure Blob Storage, Azure DevOps for CI/CD.
• Cost: The estimated monthly cost for running the application in Azure was $300 (after optimizing resource sizes). This was a significant improvement compared to the cost of maintaining the on-premises server.
• Outcome: Bob’s Burgers experienced a 99.9% uptime, improved performance, and enhanced security. They were also able to scale their application more easily to handle peak loads.

To ensure a smooth transition, we followed Azure best practices. We also made sure to document everything thoroughly.

Before the migration, we conducted a thorough assessment of Bob’s existing infrastructure and applications. This assessment helped us identify potential risks and challenges. To learn more about avoiding pitfalls, check out our article on common mistakes to avoid in cloud migrations. We also provided Bob with training on how to use Azure. This training helped him to manage his new cloud environment effectively.
