What is Landing Zone in Azure? How to implement it via Terraform

March 16, 2023 Architecture, Architectures, Azure, Azure Kubernetes Service(AKS), Azure Solution Architect Expert, Best Practices, Cloud Computing, Emerging Technologies, Kubernetes, Microsoft, Software/System Design, Terraform No comments

In Azure, a landing zone is a pre-configured environment that provides a baseline for hosting workloads. It helps organizations establish a secure, scalable, and well-managed environment for their applications and services. A landing zone typically includes a set of Azure resources such as networks, storage accounts, virtual machines, and security controls.

Implementing a landing zone in Azure can be a complex task, but it can be simplified by using Infrastructure as Code (IaC) tools like Terraform. Terraform allows you to define and manage infrastructure as code, making it easier to create, modify, and maintain your landing zone.

Here are the steps to implement a landing zone in Azure using Terraform:

  1. Define your landing zone architecture: Decide on the resources you need to include in your landing zone, such as virtual networks, storage accounts, and virtual machines. Create a Terraform module for each resource, and define the parameters and variables for each module.
  2. Create a Terraform configuration file: Create a main.tf file and define the Terraform modules you want to use. Use the Azure provider to specify your subscription and authentication details.
  3. Initialize your Terraform environment: Run the ‘terraform init’ command to initialize your Terraform environment and download any necessary plugins.
  4. Plan your deployment: Run the ‘terraform plan’ command to see a preview of the changes that will be made to your Azure environment.
  5. Apply your Terraform configuration: Run the ‘terraform apply’ command to deploy your landing zone resources to Azure.

By implementing a landing zone in Azure using Terraform, you can ensure that your environment is consistent, repeatable, and secure. Terraform makes it easier to manage your infrastructure as code, so you can focus on developing and deploying your applications and services.

Once the landing zone architecture is defined, it can be implemented using various automation tools such as Azure Resource Manager (ARM) templates, Azure Blueprints, or Terraform. In this blog, we will focus on implementing a landing zone using Terraform.

Terraform is a widely used infrastructure-as-code tool that allows us to define and manage our infrastructure as code. It provides a declarative language that allows us to define our desired state, and then it takes care of creating and managing resources to meet that state.

To implement a landing zone using Terraform, we can follow these steps:

  1. Define the landing zone architecture: As discussed earlier, we need to define the architecture for our landing zone. This includes defining the network topology, security controls, governance policies, and management tools.
  2. Create a Terraform project: Once the landing zone architecture is defined, we can create a Terraform project to manage the infrastructure. This involves creating Terraform configuration files that define the resources to be provisioned.
  3. Define the Terraform modules: We can define Terraform modules to create reusable components of infrastructure. These modules can be used across multiple projects to ensure consistency and standardization.
  4. Configure Terraform backend: We need to configure the Terraform backend to store the state of our infrastructure. Terraform uses this state to understand the current state of our infrastructure and to make necessary changes to achieve the desired state.
  5. Initialize and apply Terraform configuration: We can initialize the Terraform configuration by running the terraform init command. This command downloads the necessary provider plugins and sets up the backend. Once initialized, we can apply the Terraform configuration using the terraform apply command. This command creates or updates the resources to match the desired state.

By implementing a landing zone using Terraform, we can ensure that our infrastructure is consistent, compliant, and repeatable. We can easily provision new environments, applications, or services using the same architecture and governance policies. This can reduce the time and effort required to manage infrastructure and improve the reliability and security of our applications.

Implementing Azure Landing Zone using Terraform and Reference Architecture

Below I provide general guidance on the steps involved in implementing an Azure Landing Zone using Terraform and the Azure Reference Architecture.

Here are the general steps:

  1. Create an Azure Active Directory (AD) tenant and register an application in the tenant.
  2. Create a Terraform module for the initial deployment of the Azure Landing Zone. This module should include the following:
    • A virtual network with subnets and network security groups.
    • A jumpbox virtual machine for accessing the Azure environment.
    • A storage account for storing Terraform state files.
    • An Azure Key Vault for storing secrets.
    • A set of Resource Groups that organize resources for management, data, networking, and security.
    • An Azure Policy that enforces resource compliance with standards.
  3. Implement the Reference Architecture for Azure Landing Zone using Terraform modules.
  4. Create a Terraform workspace for each environment (dev, test, prod) and deploy the Landing Zone.
  5. Set up and configure additional services in the environment using Terraform modules, such as Azure Kubernetes Service (AKS), Azure SQL Database, and Azure App Service.

Conclusion

Implementing an Azure Landing Zone using Terraform can be a powerful way to manage your cloud infrastructure. By automating the deployment of foundational resources and configuring policies and governance, you can ensure consistency, security, repeatable, and compliance across all of your Azure resources. Terraform’s infrastructure as code approach also makes it easy to maintain and update your Landing Zone as your needs evolve. This can help us reduce the time and effort required to manage our infrastructure and improve the reliability and security of our applications.

Whether you’re just getting started with Azure or looking to improve your existing cloud infrastructure, implementing an Azure Landing Zone with Terraform is definitely worth considering. With the right planning, tooling, and expertise, you can create a secure, scalable, and resilient cloud environment that meets your business needs.

Example Code

  1. Implementing Azure Landing Zone using Terraform :

Here’s an example Terraform code snippet that creates an Azure Landing Zone with a virtual network, subnets, and a network security group:

  • Define the subscription and resource group using Terraform:
#hcl coderesource "azurerm_resource_group" "landing_zone_rg" {
  name     = "landing-zone-rg"
  location = var.location
}

resource "azurerm_virtual_network" "landing_zone_vnet" {
  name                = "landing-zone-vnet"
  address_space       = ["10.0.0.0/16"]
  location            = var.location
  resource_group_name = azurerm_resource_group.landing_zone_rg.name

  subnet {
    name           = "web-subnet"
    address_prefix = "10.0.1.0/24"
  }

  subnet {
    name           = "db-subnet"
    address_prefix = "10.0.2.0/24"
  }
}
resource "azurerm_network_security_group" "landing_zone_nsg" {
  name                = "landing-zone-nsg"
  location            = var.location
  resource_group_name = azurerm_resource_group.landing_zone_rg.name

  security_rule {
    name                       = "http"
    priority                   = 100
    direction                  = "Inbound"
    access                     = "Allow"
    protocol                   = "Tcp"
    source_port_range          = "*"
    destination_port_range     = "80"
    source_address_prefix      = "*"
    destination_address_prefix = "*"
  }

  security_rule {
    name                       = "ssh"
    priority                   = 200
    direction                  = "Inbound"
    access                     = "Allow"
    protocol                   = "Tcp"
    source_port_range          = "*"
    destination_port_range     = "22"
    source_address_prefix      = "*"
    destination_address_prefix = "*"
  }
}
resource "azurerm_network_security_group" "nsg-web" {
  name                = "nsg-web-dev"
  location            = azurerm_resource_group.resource_group.location
  resource_group_name = azurerm_resource_group.resource_group.name
}

resource "azurerm_network_security_group" "nsg-db" {
  name                = "nsg-db-dev"
  location            = azurerm_resource_group.resource_group.location
  resource_group_name = azurerm_resource_group.resource_group.name
}

resource "azurerm_subnet_network_security_group_association" "web-nsg" {
  subnet_id                 = azurerm_virtual_network.virtual_network.subnet_web.id
  network_security_group_id = azurerm_network_security_group.nsg-web.id
}

resource "azurerm_subnet_network_security_group_association" "db-nsg" {
  subnet_id                 = azurerm_virtual_network.virtual_network.subnet_db.id
  network_security_group_id = azurerm_network_security_group.nsg-db.id
}

This Terraform code creates a resource group, a virtual network, a subnet, and two additional subnet for web-frontend, db-backend , associated network security groups, and associates the subnet with the network security group. The network security group allows inbound traffic on port 22 (SSH) and port 80 (HTTP). This is just an example, and the security rules can be customized as per the organization’s security policies.

  • Create an Azure Kubernetes Service (AKS) cluster:
#hcl code
resource "azurerm_kubernetes_cluster" "aks" {
  name                = "aks-dev"
  location            = azurerm_resource_group.resource_group.location
  resource_group_name = azurerm_resource_group.resource_group.name
  dns_prefix          = "aks-dev"

  default_node_pool {
    name            = "default"
    node_count      = 1
    vm_size         = "Standard_D2s_v3"
    os_disk_size_gb = 30
  }
}

2. Implementing Azure Landing Zone using Terraform and Cloud Adoption Framework:

Cloud Adoption Framework for Azure provides a set of recommended practices for building and managing cloud-based applications. You can use Terraform to implement these best practices in your Azure environment.

Here’s an example of implementing a landing zone for a development environment using Terraform and the Cloud Adoption Framework modules:

security groups using the Azure Cloud Adoption Framework (CAF) Terraform modules:

#hcl code
provider "azurerm" {
  features {}
}

module "caf" {
  source  = "aztfmod/caf/azurerm"
  version = "5.3.0"

  naming_prefix               = "myproject"
  naming_suffix               = "dev"
  resource_group_location     = "eastus"
  resource_group_name         = "rg-networking-dev"
  diagnostics_log_analytics   = false
  diagnostics_event_hub       = false
  diagnostics_storage_account = false

  custom_tags = {
    Environment = "Dev"
  }

  # Define the virtual network
  virtual_networks = {
    my_vnet = {
      address_space = ["10.0.0.0/16"]
      dns_servers   = ["8.8.8.8", "8.8.4.4"]

      subnets = {
        frontend = {
          cidr           = "10.0.1.0/24"
          enforce_public = true
        }
        backend = {
          cidr = "10.0.2.0/24"
        }
      }

      nsgs = {
        frontend = {
          rules = [
            {
              name                       = "HTTP"
              priority                   = 100
              direction                  = "Inbound"
              access                     = "Allow"
              protocol                   = "Tcp"
              source_port_range          = "*"
              destination_port_range     = "80"
              source_address_prefix      = "*"
              destination_address_prefix = "*"
            }
          ]
        }
      }
    }
  }
}

In this example, the aztfmod/caf/azurerm module is used to create a virtual network with two subnets (frontend and backend) and a network security group (NSG) applied to the frontend subnet. The NSG has an inbound rule allowing HTTP traffic on port 80.

Note that the naming_prefix and naming_suffix variables are used to generate names for the resources created by the module. The custom_tags variable is used to apply custom tags to the resources.

This is just one example of how the Azure Cloud Adoption Framework Terraform modules can be used to create a landing zone. There are many other modules available for creating other types of resources, such as virtual machines, storage accounts, and more.

Due to the complexity and length of the example code for implementing Azure Landing Zone using Terraform and Reference Architecture, it is not possible to provide it within a blog article.

However, here are the high-level steps and an overview of the code structure:

  1. Define the variables and providers for Azure and Terraform.
  2. Create the Resource Group for the Landing Zone and networking resources.
  3. Create the Virtual Network and Subnets with the appropriate address spaces.
  4. Create the Network Security Groups and associate them with the appropriate Subnets.
  5. Create the Bastion Host for remote access to the Virtual Machines.
  6. Create the Azure Firewall to protect the Landing Zone resources.
  7. Create the Storage Account for Terraform state files.
  8. Create the Key Vault for storing secrets and keys.
  9. Create the Log Analytics Workspace for monitoring and logging.
  10. Create the Azure Policy Definitions and Assignments for enforcing governance.

The code structure follows the Cloud Adoption Framework (CAF) for Azure landing zones and is organized into the following directories:

  • variables: Contains the variables used by the Terraform code.
  • providers: Contains the provider configuration for Azure and Terraform.
  • resource-groups: Contains the code for creating the Resource Group and networking resources.
  • virtual-networks: Contains the code for creating the Virtual Network and Subnets.
  • network-security-groups: Contains the code for creating the Network Security Groups and associating them with the Subnets.
  • bastion: Contains the code for creating the Bastion Host.
  • firewall: Contains the code for creating the Azure Firewall.
  • storage-account: Contains the code for creating the Storage Account for Terraform state files.
  • key-vault: Contains the code for creating the Key Vault for secrets and keys.
  • log-analytics: Contains the code for creating the Log Analytics Workspace.
  • policy: Contains the code for creating the Azure Policy Definitions and Assignments.

Each directory contains a main.tf file with the Terraform code, as well as any necessary supporting files such as variables and modules.

Overall, implementing an Azure Landing Zone using Terraform and Reference Architecture requires a significant amount of planning and configuration. However, the end result is a well-architected, secure, and scalable environment that can serve as a foundation for your cloud-based workloads.

It’s important to note that the specific code required for this process will depend on your organization’s specific needs and requirements. Additionally, implementing an Azure Landing Zone can be a complex process and may require assistance from experienced Azure and Terraform professionals.

GitOps with a comparison between Flux and ArgoCD and which one is better for use in Azure AKS

March 15, 2023 Azure, Azure, Azure DevOps, Azure Kubernetes Service(AKS), Cloud Computing, Development Process, DevOps, DevSecOps, Emerging Technologies, GitOps, KnowledgeBase, Kubernates, Kubernetes, Microsoft, Orchestrator, Platforms, SecOps No comments

GitOps has emerged as a powerful paradigm for managing Kubernetes clusters and deploying applications. Two popular tools for implementing GitOps in Kubernetes are Flux and ArgoCD. Both tools have similar functionalities, but they differ in terms of their architecture, ease of use, and integration with cloud platforms like Azure AKS. In this blog, we will compare Flux and ArgoCD and see which one is better for use in Azure AKS.

Flux:

Flux is a GitOps tool that automates the deployment of Kubernetes resources by syncing them with a Git repository. It supports multiple deployment strategies, including canary, blue-green, and A/B testing. Flux has a simple architecture that consists of two components: a controller and an agent. The controller watches a Git repository for changes, while the agent runs on each Kubernetes node and applies the changes to the cluster. Flux can be easily integrated with Azure AKS using the Flux Helm Operator, which allows users to manage their Helm charts using GitOps.

ArgoCD:

ArgoCD is a GitOps tool that provides a declarative way to deploy and manage applications on Kubernetes clusters. It has a powerful UI that allows users to visualize the application state and perform rollbacks and updates. ArgoCD has a more complex architecture than Flux, consisting of a server, a CLI, and an agent. The server is responsible for managing the Git repository, while the CLI provides a command-line interface for interacting with the server. The agent runs on each Kubernetes node and applies the changes to the cluster. ArgoCD can be integrated with Azure AKS using the ArgoCD Operator, which allows users to manage their Kubernetes resources using GitOps.

GitOps is a relatively new approach to software delivery that has been gaining popularity in recent years. It is a set of practices for managing and deploying infrastructure and applications using Git as the single source of truth. In this blog post, we will explore the concept of GitOps, its key benefits, and some examples of how it is being used in the industry.

What is GitOps?

GitOps is a modern approach to software delivery that is based on the principles of Git and DevOps. It is a way of managing infrastructure and application deployments using Git as the single source of truth. The idea behind GitOps is to use Git to store the desired state of the infrastructure and applications, and then use automated tools to ensure that the actual state of the system matches the desired state.

The key benefit of GitOps is that it provides a simple, repeatable, and auditable way to manage infrastructure and application deployments. By using Git as the source of truth, teams can easily manage changes to the system and roll back to previous versions if needed. GitOps also provides a way to enforce compliance and security policies, as all changes to the system are tracked in Git.

How does GitOps work?

GitOps works by using Git as the single source of truth for managing infrastructure and application deployments. The desired state of the system is defined in a Git repository, and then automated tools are used to ensure that the actual state of the system matches the desired state.

The Git repository contains all of the configuration files and scripts needed to define the system. This includes everything from Kubernetes manifests to database schema changes. The Git repository also contains a set of policies and rules that define how changes to the system should be made.

Automated tools are then used to monitor the Git repository and ensure that the actual state of the system matches the desired state. This is done by continuously polling the Git repository and comparing the actual state of the system to the desired state. If there are any differences, the automated tools will take the necessary actions to bring the system back into compliance with the desired state.

With GitOps, infrastructure and application deployments are automated and triggered by changes to the Git repository. This approach enables teams to implement Continuous Delivery for their infrastructure and applications, allowing them to deploy changes faster and more frequently while maintaining stability.

GitOps relies on a few key principles to make infrastructure and application management more streamlined and efficient. These include:

  • Declarative Configuration: GitOps uses declarative configuration to define infrastructure and application states. This means that rather than writing scripts to configure infrastructure or applications, teams define the desired end state and let GitOps tools handle the rest.
  • Automation: With GitOps, deployments are fully automated and triggered by changes to the Git repository. This ensures that infrastructure and application states are always up to date and consistent across environments.
  • Version Control: GitOps relies on version control to ensure that all changes to infrastructure and application configurations are tracked and documented. This allows teams to easily roll back to previous versions of the configuration in case of issues or errors.
  • Observability: GitOps tools provide visibility into the state of infrastructure and applications, making it easy to identify issues and troubleshoot problems.

Key benefits of GitOps

GitOps offers several key benefits for managing infrastructure and application deployments:

  • Consistency: By using Git as the source of truth, teams can ensure that all changes to the system are tracked and auditable. This helps to enforce consistency across the system and reduces the risk of configuration drift.
  • Collaboration: GitOps encourages collaboration across teams by providing a single source of truth for the system. This helps to reduce silos and improve communication between teams.
  • Speed: GitOps enables teams to deploy changes to the system quickly and easily. By using automated tools to manage the deployment process, teams can reduce the time and effort required to make changes to the system.
  • Scalability: GitOps is highly scalable and can be used to manage large, complex systems. By using Git as the source of truth, teams can easily manage changes to the system and roll back to previous versions if needed.

Comparison between GitOps and Traditional Infrastructure Management:

  1. Deployment Speed: Traditional infrastructure management requires a lot of manual effort, which can result in delays and mistakes. With GitOps, the entire deployment process is automated, which significantly speeds up the deployment process.
  2. Consistency: In traditional infrastructure management, it’s easy to make mistakes or miss steps in the deployment process, leading to inconsistent deployments. GitOps, on the other hand, ensures that deployments are consistent and adhere to the same process, thanks to the version control system.
  3. Scalability: Traditional infrastructure management can be challenging to scale due to the manual effort required. GitOps enables scaling by automating the entire deployment process, ensuring that all deployments adhere to the same process and standard.
  4. Collaboration: In traditional infrastructure management, collaboration can be a challenge, especially when multiple teams are involved. With GitOps, collaboration is made easier since everything is version-controlled, making it easy to track changes and collaborate across teams.
  5. Security: Traditional infrastructure management can be prone to security vulnerabilities since it’s often difficult to track changes and ensure that all systems are up-to-date. GitOps improves security by ensuring that everything is version-controlled, making it easier to track changes and identify security issues.

Examples of GitOps in Action

Here are some examples of GitOps in action:

  1. Kubernetes: GitOps is widely used in Kubernetes environments, where a Git repository is used to store the configuration files for Kubernetes resources. Whenever a change is made to the repository, it triggers a deployment of the updated resources to the Kubernetes cluster.
  2. CloudFormation: In Amazon Web Services (AWS), CloudFormation is used to manage infrastructure as code. GitOps can be used to manage CloudFormation templates stored in a Git repository, enabling developers to manage infrastructure using GitOps principles.
  3. Terraform: Terraform is an open-source infrastructure as code tool that is widely used in the cloud-native ecosystem. GitOps can be used to manage Terraform code, allowing teams to manage infrastructure in a more repeatable and auditable manner.
  4. Helm: Helm is a package manager for Kubernetes, and it is commonly used to manage complex applications in Kubernetes. GitOps can be used to manage Helm charts, enabling teams to deploy and manage applications using GitOps principles.
  5. Serverless: GitOps can also be used to manage serverless environments, where a Git repository is used to store configuration files for serverless functions. Whenever a change is made to the repository, it triggers a deployment of the updated functions to the serverless environment.
