Azure and Terraform

Simple and Powerful

HashiCorp Terraform enables you to safely and predictably create, change, and improve infrastructure. It is an open source tool that codifies APIs into declarative configuration files that can be shared among team members, treated as code, edited, reviewed, and versioned.

The following table is a quick comparison feedback between Terraform and Azure ARM template.

Comparison Terraform ARM Template
Pro Common language to deal with several providers (Azure including AzureRm and Azure AD, AWS, Nutanix, VMware, Docker,…)

Detect if a resource’s parameter could be updated in place or if the resources need to be re created

Compliant test could be done easily to ensure that what you have deployed remains coherent

Facilitating CICD testing as the “plan” function tells you exactly what need to be done

If the Terraform resource doesn’t exist we can execute ARM template from the Terraform resource “azurerm_template_deployment”
Microsoft Azure ownership

Detect if a resource’s parameter could be updated in place or if the resources need to be re created through the What-if feature

Compliant test could be done easily to ensure that what you have deployed remains coherent through the What-if feature

Facilitating CICD testing as the the What-if feature tells you exactly what need to be done

If the ARM template could not be used, we can launch a Deployment Scripts from an ARM template

Variety of parameters types

Deployment log stored in the Azure Resource Group
Cons Could not use secure object as parameter

New release might not be delivered as fast if it was the provider own tool
AzureRm only, we can mitigate this cons using Deployment Scripts

The deployment mode “complete” permits to guarantee that your RG contains exactly what you want but the ARM template could be hard to read depending on the number of resources you put on it

About the Terraform’s modules

On of the objective here is to share Terraform custom modules with the community with the following guidelines :
