Practical guide to Azure deployment: Tools, tutorial, and tips

How do you deploy applications to Azure?

To deploy applications to Azure, developers typically start by selecting an appropriate deployment service based on their project needs. For applications requiring minimal configuration, Azure App Service provides a platform-as-a-service (PaaS) option for quickly deploying web apps, APIs, or mobile backends.

Developers can use CI/CD pipelines integrated with Azure DevOps or GitHub Actions to automate deployments, reducing manual intervention. For more complex applications, such as microservices-based systems, Azure Kubernetes Service (AKS) offers container orchestration, allowing developers to deploy and scale containerized workloads easily.

The deployment process often involves defining infrastructure using infrastructure-as-code (IaC) tools like Azure Resource Manager (ARM) templates or Azure Bicep. These tools allow teams to define the necessary resources—such as virtual machines, storage accounts, or databases—in a declarative format. The configuration can then be deployed programmatically using interfaces like Azure CLI or Azure PowerShell, ensuring repeatability and consistency across environments.

This is part of a series of articles about cloud deployment.

Example: Deploy an application to Azure Kubernetes Service

Here’s an outline of the process for deploying a sample application using AKS. These instructions are adapted from the Azure documentation.

1. Update the Kubernetes manifest file

The Kubernetes manifest file defines the configuration of your application and the associated resources. To deploy your application, start by updating the manifest file (e.g., aks-store-quickstart.yaml) to reference your container images stored in Azure Container Registry (ACR).

1. First, retrieve your ACR login server name using the Azure CLI command:

   az acr list --resource-group <resource-group> --query "[].{acrLoginServer:loginServer}" --output table

2. Then, open the manifest file and replace placeholders (e.g., ghcr.io/azure-samples) in the image property with your ACR login server name. For example:

   containers:
     - name: order-service
       image: <acrName>.azurecr.io/aks-store-demo/order-service:latest

3. Save the updated file to apply the changes.

2. Deploy the application

To implement deployment:

1. Use the kubectl apply command to deploy the application to the Kubernetes cluster. This command reads the manifest file and creates the defined resources in the cluster:

   kubectl apply -f aks-store-quickstart.yaml

2. After running the command, verify that the resources, such as deployments and services, are successfully created. You can check the status of your pods with:

   kubectl get pods

3. Expose and test the application

When the application runs, a Kubernetes service (e.g., a LoadBalancer) exposes the application to the internet.

1. To monitor this process, use:

   kubectl get service store-front --watch

2. Initially, the EXTERNAL-IP for the service might show as <pending>. Wait for it to update to a public IP address. Once the IP address is available, you can stop the watch process using CTRL-C.

3. Visit the application by navigating to the external IP address in a web browser, for example:

   http://<external-ip>

4. If the application does not load, it could be due to authorization issues with the container registry. In this case, ensure the AKS cluster is authenticated with Azure Container Registry.

4. Clean up resources

After validating that the application is running successfully, you can clean up the deployed resources to prepare for future deployments.

1. Use the following command to delete the application:

   kubectl delete -f aks-store-quickstart.yaml

2. Confirm that the application pods have been removed by running:

   kubectl get pods

5 best practices for Azure deployment

By implementing the following best practices, organizations can ensure the most effective deployment in Azure.
