Learn about the benefits of adopting Terraform IaC for platform teams, including efficient cloud provisioning, collaboration, and compliance. Explore practical strategies for adoption and real-world use cases.
Most platform teams would agree that managing cloud infrastructure can be complex and time-consuming.
By adopting Terraform infrastructure as code (IaC), platform teams can streamline cloud provisioning and management through infrastructure automation.
In this post, you'll learn what Terraform IaC is, the benefits it offers for platform teams, and practical strategies for adoption to enable efficient infrastructure operations.
Managing cloud infrastructure can become complex as organizations scale their footprint across multiple environments and cloud providers. This leads to infrastructure sprawl and inconsistencies that make management difficult. Adopting Infrastructure as Code (IaC) practices with Terraform can help address these challenges.
Terraform provides consistency and efficiency by enabling infrastructure to be described as code and applied across environments. Key benefits include:
By adopting Terraform IaC, platform teams gain efficiency, reduce risk, and enable collaboration for cloud infrastructure efforts.
Terraform is a popular open source IaC tool that provides a consistent workflow for managing infrastructure across public cloud providers. Key aspects that make Terraform a gateway to efficient cloud provisioning include:
For platform teams overseeing cloud environments, Terraform improves efficiency by enabling collaboration around infrastructure as code. Changes are easily tracked, resources are consistently provisioned, and environments are easily replicated.
By adopting Terraform IaC methodology, teams streamline cloud provisioning and reduce risk around manual processes. This empowers developers with self-service access while maintaining oversight, compliance and cost optimization.
Terraform is an open-source Infrastructure as Code (IaC) tool that provides a consistent CLI workflow to manage hundreds of cloud services. Terraform codifies cloud APIs into declarative configuration files.
This allows infrastructure to be described as code and enables users to version, test, and share their infrastructure in a codified manner. Teams use Terraform to manage infrastructure safely and efficiently.
Terraform provides several key benefits:
Infrastructure as Code - Infrastructure is codified, allowing changes to be made and versioned just like application code. This improves efficiency and reduces human error.
Execution Plans - Terraform has a planning stage where it generates an execution plan showing what infrastructure will be created or changed. This allows teams to preview changes before applying them.
Resource Graph - Terraform understands resource relationships, allowing it to determine creation order and parallelize operations for faster infrastructure builds.
Change Automation - Complex change sets across resources can be applied in an automated manner. Teams spend less time on manual tasks and reduce risk.
Multicloud - Terraform supports most major cloud providers, allowing a consistent workflow across AWS, Azure, GCP and more. This simplifies management for multicloud environments.
By codifying infrastructure and processes, Terraform provides teams a scalable approach to manage infrastructure efficiently and safely in dynamic cloud environments. Its growing provider ecosystem and large community make it a versatile IaC tool for organizations.
Terraform is considered one of the best infrastructure as code (IaC) tools available today for several key reasons:
Provider ecosystem - Terraform has over 1000 providers across major cloud platforms like AWS, Azure, and GCP as well as Kubernetes, OpenStack, and more. This extensive provider ecosystem allows teams to manage nearly any infrastructure with a consistent workflow.
Declarative syntax - Terraform uses a declarative language called HCL (HashiCorp Configuration Language) to define desired infrastructure states. This makes infrastructure easy to visualize and collaborate on.
Plan and apply model - Terraform has a plan and apply model for change management. The plan stage lets teams preview changes before the apply stage provisions real infrastructure.
State management - Terraform remote state allows teams to store state in a backend like S3 or Terraform Cloud. This facilitates collaboration and helps prevent state file corruption.
Maturity - Released in 2014, Terraform has many years of production use and is backed by HashiCorp. The tool is mature, stable, and trusted by organizations worldwide.
While there are other good IaC options, Terraform stands out for its provider breadth, approachability, safety, and production-readiness. Its declarative style, planning workflow, and remote state management help platform teams implement robust IaC practices efficiently. For most organizations, Terraform strikes the right balance of power and usability.
Infrastructure as Code (IaC) and DevOps are complementary practices that enable organizations to efficiently manage and deploy cloud infrastructure and applications. Here are some key differences:
So in summary, IaC handles provisioning cloud infrastructure while DevOps facilitates deploying apps onto that infrastructure efficiently. Together they enable fully automated application delivery workflows.
Ansible and Terraform are two major Infrastructure as Code (IaC) tools that help enterprises create configurations and scale them easily. Both tools act as advanced-level platforms in deploying complex applications.
There are some key differences between Ansible and Terraform:
Purpose: Ansible is mainly used for configuration management whereas Terraform focuses on infrastructure provisioning. Ansible ensures systems are configured correctly while Terraform provisions the infrastructure.
Approach: Ansible uses an imperative approach, executing tasks in a defined order. Terraform uses a declarative approach, specifying the desired end state.
Flexibility: Ansible works over SSH and can be used across operating systems. Terraform relies on providers and is focused on infrastructure.
Integration: Ansible integrates with various tools through Ansible Tower. Terraform has limited integration capabilities currently.
Learning Curve: Ansible has a gentler learning curve compared to HashiCorp Configuration Language (HCL) used in Terraform.
In summary, Ansible and Terraform can complement each other in infrastructure management. Ansible ensures correct configuration while Terraform provisions and scales the infrastructure. Using them together provides flexibility and automation across infrastructure environments.
Platform teams can benefit from integrating Ansible and Terraform in their infrastructure as code (IaC) approach:
An integrated approach with Terraform and Ansible allows platform teams to streamline cloud operations, enhance efficiency through automation, and improve scalability. The infrastructure can be easily replicated across environments due to the IaC capabilities.
Overall, combining these technologies based on their strengths and weaknesses allows organizations to optimize infrastructure management.
Terraform is an open source infrastructure as code (IaC) tool that provides a consistent CLI workflow to manage hundreds of cloud services. Terraform codifies cloud APIs into declarative configuration files.
Terraform allows teams to define infrastructure in human-readable configuration files that can be shared amongst team members. These configuration files serve as the single source of truth for the infrastructure.
Some key benefits of Terraform IaC:

Some key components of Terraform:
Compared to other Infrastructure as Code (IaC) tools like CloudFormation and Ansible, some benefits Terraform provides:
This section details best practices for platform teams to effectively adopt Terraform IaC within their cloud management processes.
Terraform modules allow teams to build reusable, composable infrastructure components that abstract away unnecessary details and enable collaboration. By providing a library of approved Terraform modules, platform teams can:
To scale module adoption:
With well-structured modules, developers can quickly build infrastructure while platform teams maintain guardrails.
By integrating Terraform into CI/CD pipelines, infrastructure changes can be validated and applied in a consistent, compliant way. Best practices include:
terraform fmt, validate and plan in CI to prevent malformed, noncompliant or disruptive changes from deployingterraform apply, with approvals for productionFollowing these patterns, platform teams can enable developer velocity through Terraform while retaining appropriate control and visibility.
Terraform remote state is a powerful feature for collaboration, but mismanagement can lead to issues like state corruption and configuration drift. Recommendations include:
With robust state management and disaster recovery practices, platform teams can provide reliable foundations for developers building infrastructure.
Terraform is a powerful infrastructure as code (IaC) tool that enables developers to programmatically provision and manage infrastructure across various providers. As organizations continue their cloud journeys, Terraform usage is accelerating for automating infrastructure workflows.
Here are some common real-world use cases where Terraform delivers immense value:
Kubernetes has become the de-facto standard for container orchestration. With Terraform, developers can declaratively define and provision Kubernetes clusters across on-premises and cloud environments like AWS, Azure, and GCP.
Key benefits include:
Overall, Terraform simplifies Kubernetes infrastructure automation across teams and clouds.
Maintaining compliance in dynamic cloud environments can be challenging. With Terraform, infrastructure can be validated against security policies and compliance requirements before provisioning.
For example:
This "compliance as code" approach shifts security left and enables preventative governance. Teams save time and reduce risk.
Organizations often leverage multiple cloud providers (AWS, Azure, GCP) and on-prem environments. Terraform provides a consistent workflow to provision infrastructure across these heterogeneous platforms.
Benefits include:
With Terraform, multicloud management is simplified.
Terraform is an open source infrastructure as code (IaC) tool that allows you to define, provision, and manage infrastructure in a safe, consistent, and repeatable manner. As a platform team looking to adopt IaC practices, Terraform is an excellent place to start.
Let's walk through some hands-on examples of using Terraform for infrastructure management.
To demonstrate Terraform in action, we'll build a simple AWS architecture consisting of a VPC, public/private subnets across two availability zones, an internet gateway, route table, and security groups.
First, we configure the AWS provider in main.tf:
provider "aws" {
region = "us-east-1"
}
Next, we create the VPC resources in vpc.tf:
# Create VPC
resource "aws_vpc" "example" {
cidr_block = "10.0.0.0/16"
}
# Create public subnets
resource "aws_subnet" "public" {
vpc_id = aws_vpc.example.id
cidr_block = "10.0.1.0/24"
availability_zone = "us-east-1a"
tags = {
Name = "Public Subnet 1"
}
}
# Create private subnets
resource "aws_subnet" "private" {
vpc_id = aws_vpc.example.id
cidr_block = "10.0.2.0/24"
availability_zone = "us-east-1b"
tags = {
Name = "Private Subnet 1"
}
}
We handle routing, gateways, and security groups similarly. When ready, we provision resources with terraform apply. This demonstrates how Terraform allows declarative infrastructure management for AWS.
Let's walk through building a Terraform configuration from scratch. We'll use the Azure provider as an example.
First, configure the provider block with subscription ID:
provider "azurerm" {
subscription_id = "xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
}
Next, define the resource to create, like a resource group:
resource "azurerm_resource_group" "example" {
name = "resourceGroup1"
location = "West US 2"
}
We can add outputs to print created resource attributes:
output "resource_group_id" {
value = azurerm_resource_group.example.id
}
This covers the basics - a provider, resource definition, and output. We execute with:
terraform init
terraform apply
This initializes the provider and provisions the resource group. The output prints the id.
As infrastructure grows, we can use modules to package and reuse configurations. Modules allow abstraction and encapsulation for simplified management.
We can also use backends to store state remotely instead of locally. Backends improve collaboration by enabling state sharing between team members.
For example, we may use a Azure storage backend:
terraform {
backend "azurerm" {
storage_account_name = "myaccount"
container_name = "tfstate"
key = "prod.terraform.tfstate"
}
}
This allows persistent storage of state in a Azure blob container instead of on a local machine.
Terraform Cloud provides a SaaS backend to enable teams to collaborate on infrastructure in a centralized platform. Features include:
With Terraform Cloud, teams can standardize practices around Terraform to scale infrastructure management.
In closing, adopting Terraform IaC enables platform teams to improve cloud infrastructure efficiency, collaboration and compliance while reducing risk.
Terraform IaC provides several key benefits for platform teams managing cloud infrastructure:
