Using Azure CLI to Deploy AKS

The Azure CLI is one of the fastest ways to create and manage AKS clusters. Here’s a step-by-step guide to deploying your first cluster:

1. Install the Azure CLI and log in using az login.
2. Create a resource group: az group create --name myResourceGroup --location eastus.
3. Create the AKS cluster: az aks create --resource-group myResourceGroup --name myAKSCluster --node-count 2 --enable-addons monitoring --generate-ssh-keys.
4. Install kubectl: az aks install-cli.
5. Connect to the cluster: az aks get-credentials --resource-group myResourceGroup --name myAKSCluster.

Once connected, you can deploy a sample application using kubectl apply -f deployment.yaml. This method is ideal for developers who want quick feedback and iterative testing.

Infrastructure as Code with Terraform

For production environments, Infrastructure as Code (IaC) is essential for consistency, version control, and repeatability. Terraform is widely used to define AKS clusters declaratively.

Kubernetes Service (AKS) – Kubernetes Service (AKS) menjadi aspek penting yang dibahas di sini.

• Define provider configurations for Azure.
• Create a virtual network and subnet for the cluster.
• Configure the AKS resource with node pools, RBAC, and add-ons.

Here’s a simplified Terraform snippet:

resource "azurerm_kubernetes_cluster" "example" {
  name                = "example-aks-cluster"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  dns_prefix          = "example-aks"

  default_node_pool {
    name       = "default"
    node_count = 2
    vm_size    = "Standard_D2_v2"
  }

  identity {
    type = "SystemAssigned"
  }
}

This approach ensures that your Kubernetes Service (AKS) environment is reproducible across development, staging, and production. You can find full examples in the Terraform Azure Provider documentation.

Scaling and Performance Optimization in AKS

One of the core promises of Kubernetes is scalability, and Kubernetes Service (AKS) delivers this with powerful built-in tools and integrations.

Horizontal Pod Autoscaler (HPA)

The Horizontal Pod Autoscaler automatically adjusts the number of pod replicas based on CPU usage or custom metrics.

• HPA monitors resource utilization via the Metrics Server.
• You can define scaling rules based on CPU, memory, or custom Prometheus metrics.
• HPA works seamlessly with AKS to ensure applications scale during traffic spikes.

Example configuration:

apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
metadata:
  name: nginx-hpa
spec:
  scaleTargetRef:
    apiVersion: apps/v1
    kind: Deployment
    name: nginx-deployment
  minReplicas: 2
  maxReplicas: 10
  metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 50

This ensures your application remains responsive under load while avoiding over-provisioning.

Cluster Autoscaler

While HPA scales pods, the Cluster Autoscaler adjusts the number of nodes in your node pool.

• It adds nodes when pods cannot be scheduled due to resource constraints.
• It removes nodes when they are underutilized for a sustained period.
• Supports multiple node pools and spot instances for cost optimization.

The Cluster Autoscaler is especially useful for unpredictable workloads or batch processing jobs. When combined with AKS, it ensures optimal resource utilization and cost efficiency. More details are available in the official AKS autoscaling guide.

Security and Compliance in Kubernetes Service (AKS)

In enterprise environments, security is non-negotiable. Kubernetes Service (AKS) provides a robust set of features to secure your clusters and comply with regulatory standards.

Role-Based Access Control (RBAC) with Azure AD

Integrating AKS with Azure Active Directory (AAD) enables fine-grained access control.

• Users and groups can be assigned Kubernetes roles (e.g., admin, viewer) via AAD.
• Conditional Access policies can enforce MFA for cluster access.
• Integration with Azure RBAC allows control over who can manage the cluster infrastructure.

This dual-layer RBAC (Azure + Kubernetes) ensures least-privilege access and auditability. For example, a developer might have read-only access to pods but no permission to modify node pools.

Network Policies and Firewalls

AKS supports network policies through Calico or Azure Network Policies to control traffic between pods.

Kubernetes Service (AKS) – Kubernetes Service (AKS) menjadi aspek penting yang dibahas di sini.

• Define ingress and egress rules to restrict communication.
• Use Azure Firewall or Application Gateway for external traffic filtering.
• Enable private clusters to isolate the API server within a virtual network.

Private clusters ensure that the Kubernetes API server is not exposed to the public internet, reducing the attack surface. This is critical for organizations handling sensitive data. Learn how to enable private clusters at Microsoft’s private AKS documentation.

Monitoring and Observability in AKS

Running containers at scale requires deep observability. Kubernetes Service (AKS) integrates with powerful monitoring tools to provide full-stack visibility.

Azure Monitor for Containers

Azure Monitor offers comprehensive monitoring for AKS clusters, including metrics, logs, and alerts.

Kubernetes Service (AKS) – Kubernetes Service (AKS) menjadi aspek penting yang dibahas di sini.

• Collects CPU, memory, and disk usage from nodes and pods.
• Integrates with Log Analytics for advanced querying using Kusto (KQL).
• Provides pre-built dashboards for cluster health and performance.

You can set up alerts for high memory usage or pod restarts, enabling proactive incident response. For example:

Kusto Query Language (KQL)
InsightsMetrics
| where Name == "
" and AggregatedValue > 90

This query identifies nodes with CPU usage above 90%, triggering an alert.

OpenTelemetry and Prometheus Integration

For teams using open-source observability stacks, AKS supports Prometheus and OpenTelemetry.

• Prometheus can be deployed via Helm to scrape metrics from applications.
• OpenTelemetry collectors can export traces and metrics to Azure Monitor or other backends.
• Grafana can be used for visualization with data from Prometheus or Azure Monitor.

This flexibility allows organizations to adopt hybrid monitoring strategies. The Azure Monitor integration with Prometheus is a game-changer for teams already invested in the CNCF ecosystem.

Cost Management and Optimization for AKS

While AKS eliminates control plane costs, node and storage expenses can add up. Effective cost management is crucial for sustainable operations.

Using Spot VMs for Non-Critical Workloads

AKS supports Azure Spot VMs, which can reduce compute costs by up to 90%.

Kubernetes Service (AKS) – Kubernetes Service (AKS) menjadi aspek penting yang dibahas di sini.

• Spot VMs are ideal for stateless, fault-tolerant, or batch workloads.
• If Azure needs the capacity back, the VM is evicted with a 30-second warning.
• You can combine spot and regular node pools for hybrid cost-performance balance.

Example use cases: CI/CD runners, data processing jobs, or staging environments.

Right-Sizing Node Pools

Choosing the right VM size and count prevents over-provisioning.

• Use Azure Advisor to get recommendations on VM size optimization.
• Monitor resource utilization to identify underused nodes.
• Consider burstable VMs (like B-series) for variable workloads.

Additionally, enabling auto-scaling ensures you only pay for what you use. Tools like Azure Cost Management help track AKS spending and forecast future costs.
