Terraform Stacks for Efficient Infrastructure Management

Voiced by Amazon Polly


Terraform, a widely adopted Infrastructure as Code (IaC) tool, has recently introduced an impactful feature known as Terraform stacks. These stacks offer a structured approach to managing infrastructure by enabling the division of complex systems into smaller, more manageable components. This article presents a practical proof of concept (POC) highlighting the advantages of leveraging the Terraform infrastructure management stack.

Terraform Stacks

Terraform stacks organize infrastructure into reusable components, each associated with a module and configured with its set of inputs. These stacks facilitate the cohesive management of related resources, ensuring that actions such as applying, destroying, or modifying a stack affect all associated resources.

This organization simplifies the management of intricate deployments and promotes modularity and scalability.

Terraform stacks revolutionize infrastructure management by introducing several key advantages

  • Modularity: By breaking down infrastructure into smaller, manageable components, Terraform stacks enhance maintainability and reliability. This modular approach allows teams to focus on individual components, facilitating easier troubleshooting and updates.
  • Lifecycle Management: Stacks streamline the management of related resources, ensuring cohesive handling during deployments. With stacks, complex deployments become more manageable as changes to one component trigger coordinated actions across the stack.
  • Variable Sharing: One of the standout features of Terraform stacks is their ability to facilitate seamless variable sharing between components. This capability empowers teams to efficiently share resources and configuration settings, promoting consistency across the infrastructure.
  • Environment Isolation: By leveraging stacks, organizations can create isolated environments for development, staging, and production. While sharing the same infrastructure code, these environments can have distinct configurations, enabling thorough testing and validation without impacting other environments.
  • State Management: Each Terraform stack maintains its own state file, reducing the risk of conflicts and simplifying state management. This granular approach enhances visibility and control, ensuring smooth operations even in complex infrastructures.

Proof of Concept

We will deploy an Amazon EC2 instance for the demonstration and modify its attributes using Terraform stacks. The project directory structure is as follows:


In the at the root level, we create an Amazon EC2 instance:

Then, in the modules/change_tags/, we define a module that changes the tags of an instance:

Finally, we use a Terraform stack to apply these modifications to the instance:


This proof of concept illustrates how Terraform stacks streamline infrastructure management by fostering modularity and structured modifications. By encapsulating related resources within stacks, organizations can efficiently manage the lifecycle of their infrastructure components, particularly in complex projects. It’s essential to note that while this example provides a simplified overview, the implementation of Terraform stacks can be tailored to suit specific project requirements and Terraform project structures.
