As cloud computing is rapidly evolving, Kubernetes has become an enabler for orchestrating containerized applications.Among the plethora of options available, two giants stand out: Microsoft’s Azure Kubernetes Service (AKS) and Amazon Web Services’ Elastic Kubernetes service (EKS). Both have their own distinctive characteristics and capabilities, which allows the choice between them to become a point of no return for organizations as well as developers.
This article embarks on an in-depth journey towards understanding and contrasting these two powerful Kubernetes services. We’ll begin by giving an overview of AKS, looking at its implementation before examining the key details as well benefits. Next, we will discuss EKS and explain the strengths of this tool as well as its features. Our expedition does not limit itself to mere descriptions; we will have a blueprint guide for setting up clusters in both environments using Terraform, an IAC tool that is widely adopted.
What makes the difference in this comparison is our practical approach. Rather than just enumerating features, we’ll look at practical use cases that include discussing and picking apart factors like ease of installation and setup, management potentials alongside cost considerations average proceedings. By the close of this article, you’ll have a better understanding on which between AKS and EKS is better for your specific case.
No matter if you’re a cloud veteran or an ambitious rookie who would like to venture the Kubernetes realm, this article is meant to provide you with useful guidance for optimal decision-making between AKS and EKS. In other words, let’s get down to this illuminating trip through the domains of Azure and AWS in order to utilize Kubernetes on cloud.
Getting Started with Azure Kubernetes Service (AKS)
The Microsoft Azure suite features one of the best container services in AKS, a powerful managed service that helps deploy manage and scale applications on Kubernetes. AKS seamlessly integrates with Azure’s core features, allowing users to easily access the benefits of Kubernetes within the confines of an Azure environment.
In this section, we’ll look at how to create an AKS cluster using Terraform. This is a popular infrastructure as code tool that allows you define provision and manage cloud infrastructures with the help of codes.
Prerequisites: Before diving into the Terraform code, ensure you have the following:
- An active Azure subscription. If you don’t have one, sign up for a free trial here.
- Azure CLI installed on your local machine. Instructions for installation can be found here.
- Terraform installed on your local machine. You can download it from Terraform’s website.
- Authenticate your Azure CLI session. Run az login and follow the instructions to log in with your Azure credentials.
Creating an AKS Cluster: Let’s use Terraform to define our AKS cluster. The configuration below illustrates the creation of an Azure resource group and AKS cluster within it through a simple Terraform.
- Define the Azure Provider: First, specify the Azure provider version and region in your Terraform configuration.
provider "azurerm" {
features {}
}
- Define the Azure Resource Group: This block of code creates a new resource group in Azure where your AKS cluster will reside.
resource "azurerm_resource_group" "aks" {
name = "myAKSResourceGroup"
location = "westus"
}
- Define the AKS Cluster: The following configuration creates an AKS cluster within the specified resource group.
resource "azurerm_kubernetes_cluster" "aks" {
name = "myAKSCluster"
location = azurerm_resource_group.aks.location
resource_group_name = azurerm_resource_group.aks.name
dns_prefix = "myAKS"
linux_profile {
admin_username = "azureuser"
ssh_key {
key_data = file("~/.ssh/id_rsa.pub")
}
}
agent_pool_profile {
name = "aksagentpool"
count = 3
vm_size = "Standard_DS2_v2"
os_type = "Linux"
}
}
After doing the above steps, you will have an AKS cluster. The configuration is also easy — building a cluster for initial investigation and development purposes.
This configuration can be further enhanced with more advanced features like network setting, scaling parameters and integration of other Azure services as you become accustomed to AKS and Terraform.
In the following section, we will now concentrate on Amazon Elastic Kubernetes Service (EKS) and how to set it up using Terraform that serves as a springboard for comparing AKS with EKS.
Introduction to Amazon Elastic Kubernetes Service (EKS)
To further cater to the needs of its clients, AWS provides Amazon Elastic Kubernetes Service (EKS) which is a fully managed service by Amazon. It offers a scalable and safe environment in which you can operate your containerized programs. Therefore, EKS is a very smart choice for those who use an Amazon cloud platform since it easily integrates with the mighty AWS ecosystem.
In this section, we will demonstrate how to create an EKS cluster using Terraform. This pragmatic perspective provided you with an understanding of how EKS works and also some practical hints regarding its implementation.
Prerequisites: Before we begin, ensure you have the following:
- An AWS account. You can create one here.
- AWS CLI installed on your local machine. Follow the installation guide here.
- Terraform installed on your local machine. Download it from Terraform’s website.
- Configure AWS CLI with your credentials using aws configure. This step will require your AWS Access Key ID and Secret Access Key.
Setting Up an EKS Cluster: Below, we provide a Terraform script to set up a basic EKS cluster. This script is a starting point and can be expanded for more complex deployments.
- Define the AWS Provider: First, specify the AWS provider version and region in your Terraform configuration.
provider "aws" {
version = "~> 3.0"
region = "us-west-2"
}
- Create an EKS Cluster: Define the EKS cluster along with the necessary computing resources, such as node groups.
resource "aws_eks_cluster" "example" {
name = "myEksCluster"
role_arn = aws_iam_role.eks.arn
vpc_config {
subnet_ids = [aws_subnet.example.id]
}
}
resource "aws_iam_role" "eks" {
name = "eksClusterRole"
assume_role_policy = jsonencode({
Version = "2012-10-17",
Statement = [{
Action = "sts:AssumeRole",
Effect = "Allow",
Principal = {
Service = "eks.amazonaws.com"
}
}]
})
}
resource "aws_eks_node_group" "example" {
cluster_name = aws_eks_cluster.example.name
node_group_name = "eks-node-group"
node_role_arn = aws_iam_role.eks_node.arn
subnet_ids = [aws_subnet.example.id]
scaling_config {
desired_size = 3
max_size = 3
min_size = 1
}
}
This Terraform script configures a simple EKS cluster. The setup includes the creation of an IAM role for EKS, defining clusters, and setting up Nodegroups for resources that compute a cluster.
EKS provides different advanced configurations including integrating with AWS Fargate for serverless compute nodes, auto-scaling and more. Over time, as you gain more experience with AWS and EKS, this simple setup can be extended to meet your exact needs.
In the following section, we will compare AKS and EKS in a practical setting using features like setup ease, management quality, scalability ability; cost efficiency and performance. This discussion will prove useful for anyone trying to select between these two reliable Kubernetes services.
