Step-by-Step: AKS Setup for Native Apps

⚠️ Attention: Why AKS is Your Key to Azure-Native Success

Developing scalable, cloud-native apps on Microsoft Azure can be challenging, especially with the complexity of containerized workloads. Azure Kubernetes Service (AKS) simplifies the challenge, providing a managed Kubernetes environment that abstracts the complexities of deploying and scaling Azure Native apps. As a cloud architect or DevOps engineer, learning how to set up AKS is essential for building secure, future-ready systems. In this tutorial, we will provide a practical step-by-step exercise to help you set up AKS for Azure Native apps so you can get involved in the deployment.

💡 Interest: The Power of AKS in Azure Cloud Native Architecture

AKS (Azure Kubernetes Service) is considered a key part of the Azure-native architecture. Allowing developers to manage containers in a consistent manner in Azure. They also receive automatic upgrades, scaling, and monitoring, which reduces the operational overhead. The intent of this guidance document is Azure-native application AKS configuration, including Azure Monitor and Bicep, to provide an Infrastructure as Code (IaC) framework. Using these means you will be able to deploy CloudCrafter-level deployments targeted at pragmatic use cases.

Here are some highlights of why AKS is preferential:

• Scalability: Pods can now scale automatically with increased traffic.

• Cost Effective: Leverage serverless resource management.

• Security: Increase the access control of the system using Azure Active Directory.

• Simplicity: Leverage Automated Managed Kubernetes to simplify operational complexity.

🚀 Desire: Build Scalable Azure Native Apps with Ease

Imagine deploying a microservices-based application on Azure with minimal hassle, where your AKS cluster handles scaling and monitoring seamlessly. This step-by-step guide will empower you to achieve that, using Azure-native tools and best practices. Whether you’re transitioning from a monolith or building a new cloud-native app, this process will help you create a scalable, secure system.

Step 1: Prepare Your Azure Environment

Before creating an AKS cluster, ensure your Azure environment is ready:

• Create a Resource Group: In the Azure Portal, create a resource group (e.g., my-aks-rg) to organize your resources.
• Set Up Azure CLI: Install the Azure CLI or use Azure Cloud Shell for command-line operations.
• Verify Permissions: Ensure your account has the “Contributor” role for the subscription.

Pro Tip: Use a consistent naming convention like aks-[project-name]-[env] for clarity.

Step 2: Create an AKS Cluster with Bicep

Using Infrastructure as Code (IaC) ensures repeatable deployments. We recommend Bicep over ARM templates for its simplicity in Azure-native setups. Here’s a sample Bicep file to create an AKS cluster:

param location string = 'eastus'
param clusterName string = 'my-aks-cluster'

resource aksCluster 'Microsoft.ContainerService/managedClusters@2023-01-01' = {
  name: clusterName
  location: location
  properties: {
    kubernetesVersion: '1.25.6'
    dnsPrefix: '${clusterName}-dns'
    agentPoolProfiles: [
      {
        name: 'agentpool'
        count: 3
        vmSize: 'Standard_D2_v2'
        osType: 'Linux'
        mode: 'System'
      }
    ]
  }
}

Save this as aks.bicep and deploy it using:

az deployment group create --resource-group my-aks-rg --template-file aks.bicep

.

Step 3: Configure kubectl for AKS

Once the cluster is created, connect it to kubectl:

az aks get-credentials --resource-group my-aks-rg --name my-aks-cluster
kubectl get nodes

---

Step 4: Deploy a Sample Azure Native App

Let’s deploy a simple microservice to test your AKS setup. Create a YAML file (sample-app.yaml):

apiVersion: apps/v1
kind: Deployment
metadata:
  name: sample-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: sample-app
  template:
    metadata:
      labels:
        app: sample-app
    spec:
      containers:
        - name: sample-app
          image: nginx:latest
          ports:
            - containerPort: 80
---
apiVersion: v1
kind: Service
metadata:
  name: sample-app-service
spec:
  selector:
    app: sample-app
  ports:
    - port: 80
      targetPort: 80
  type: LoadBalancer

Apply it with:

kubectl apply -f sample-app.yaml

Check the service URL with:

kubectl get svc

---

Step 5: Enable Monitoring with Azure Monitor

Monitoring is critical for Azure Native apps. Integrate Azure Monitor for AKS:

• In the Azure Portal, navigate to your AKS cluster.

• Enable “Container Insights” under the Monitoring section.

• View metrics like CPU usage and pod health in the Azure dashboard.

.

---

Step 6: Optimize and Scale Your AKS Cluster

To ensure cost efficiency and scalability:

• Enable Autoscaling:

kubectl autoscale deployment sample-app --cpu-percent=70 --min=3 --max=10

• Right-Size Nodes: Choose VM sizes like Standard_D2_v2 for cost-effective performance.

• Review Costs: Use Azure Cost Management to monitor expenses [insert affiliate link].

---

Step 7: Secure Your AKS Cluster

Security is paramount for AzureNative apps:

• Enable RBAC: Integrate Azure Active Directory for role-based access control.

• Network Policies: Restrict pod-to-pod communication with Kubernetes network policies.

• Regular Updates: Keep your AKS cluster on the latest Kubernetes version.

✅ Why This AKS Setup Works for AzureNative Apps

The AKS process shown here follows step-by-step using Azure-native tools like Bicep and Azure Monitor, and slides have been created for a secure and scalable environment. This means you have set up a way to deploy microservices, optimized costs, and ensured reliability. It is streamlined, as we avoided the unnecessary complexity of generic Kubernetes deployments, and we kept to the CloudCrafter culture of ease of use in Azure-native architecture.
