Most developers would agree: provisioning cloud infrastructure manually is tedious and error-prone.

But what if you could automate infrastructure deployment with code? Terraform allows you to define, provision, and manage infrastructure efficiently as version-controlled code.

In this post, we'll explore how Terraform enables infrastructure as code to streamline DevOps workflows. You'll learn Terraform's key capabilities for codifying infrastructure, harnessing multi-cloud potential, integrating with CI/CD pipelines, and embracing best practices for impactful Terraform adoption.

Introduction: Embracing Terraform for DevOps Efficiency

Terraform is revolutionizing infrastructure as code by enabling developers to define, provision, and manage cloud environments with a human-readable, declarative coding language. As organizations accelerate cloud adoption, Terraform unlocks new levels of efficiency, automation, and innovation in DevOps practices.

In just a few short years, Terraform has become the de facto standard for infrastructure as code across AWS, Azure, Google Cloud, and more. Its elegant syntax allows developers to model everything from single servers to complex multi-tier architectures. Changes made through code are version controlled, enabling collaboration while avoiding risky manual processes.

Terraform is deeply integrated with popular DevOps tools like Kubernetes, Ansible, Jenkins, and more. This makes it easy to tie automated infrastructure provisioning into CI/CD pipelines. By treating infrastructure as just another application component, teams can test locally, iterate faster, and reduce risk.

For modern development teams, Terraform delivers the automation, safety, and collaboration needed to scale cloud-native infrastructure efficiently. Its growing community and extensible provider ecosystem cement its position as a key enabler of DevOps transformation.

Is terraform an infrastructure as code?

Terraform is indeed an infrastructure as code (IaC) tool. IaC allows engineers to define, provision, and manage infrastructure in configuration files rather than using a graphical user interface.

By writing infrastructure as code, engineers can treat their infrastructure like application code:

  • Version control - Store Terraform configs in Git to track changes and enable collaboration
  • Reuse - Create reusable Terraform modules to avoid duplication
  • Validate - Catch issues early via terraform plan before provisioning
  • Automate - Build self-service workflows with Terraform to enable automation

This "shift left" brings infrastructure closer to developers and unlocks valuable benefits:

  • 🚀 Speed - Spin up environments on demand for rapid iteration
  • 🧠 Productivity - Spend time building, not on manual tasks
  • 💲 Cost - Destroy unused infrastructure easily
  • ♻️ Consistency - Standardize deployments across environments

By codifying infrastructure, Terraform serves as a "single source of truth" that facilitates collaboration between developers and ops teams. Rather than one-off manual changes, everything is captured as code that can be inspected, shared, changed, and versioned together.

This is a powerful paradigm shift that enables builders to move fast without breaking things. Treating infrastructure as code with Terraform helps streamline workflows and unlocks efficiency at scale.

What are the drawbacks of using terraform for infrastructure as code?

While Terraform is a powerful tool for infrastructure as code, it does have some drawbacks to be aware of:

The Drawbacks of Terraform

  • Drift: One issue with Terraform is drift. This occurs when the actual infrastructure diverges from what is defined in the Terraform configuration files. For example, if someone manually changes infrastructure that Terraform is managing, the files become out of sync. This often causes "drift", meaning the configuration file does not match reality.
  • Steep Learning Curve: Terraform uses a proprietary syntax, HashiCorp Configuration Language (HCL), for infrastructure configuration. This can be challenging for beginners and comes with a steep learning curve. While HCL is designed to be human-readable, becoming proficient requires an investment of time.
  • State File Dependence: Terraform relies heavily on its state file to map real world resources to the configuration. If the state file is lost or corrupted, Terraform may not know about existing infrastructure, causing significant issues.

Carefully managing these limitations allow you to use Terraform effectively for infrastructure as code. But being aware of the drawbacks is important when evaluating tools.

Is terraform a PaaS or IaaS?

Terraform is commonly used to automate and manage infrastructure as code at the Infrastructure-as-a-Service (IaaS) level, enabling configuration of cloud resources like virtual machines, load balancers, networks, etc. However, Terraform's flexibility allows it to potentially manage Platform-as-a-Service (PaaS) resources as well.

Terraform's capabilities

Terraform supports provisioning infrastructure and services across a wide variety of cloud providers and technologies. This includes not only IaaS resources like compute instances and networking, but also many PaaS layers like databases, message queues, functions, containers, and more.

Additionally, there are a growing number of SaaS services that provide Terraform integrations using provider plugins. These make services like DNS management or monitoring directly available natively within Terraform configurations.

By leveraging terraform modules and Terraform Cloud integrations, teams can automate infrastructure provisioning spanning IaaS, PaaS, and even SaaS layers, enabling broad infrastructure as code capabilities.

Unlocking automation

With Terraform's versatility to automate services across cloud technology stacks, developers can configure and provision entire application environments in parallel. Rather than dealing with separate tools and orchestration mechanisms for each layer, Terraform language provides a consistent way to describe and manage infrastructure in configurations that can deploy horizontally integrated architecture.

By codifying and automating infrastructure builds in Terraform, organizations streamline provisioning and gain efficiency. This is particularly useful for Terraform Azure and Terraform AWS builds, where resources can be intricately interdependent.

In summary, Terraform allows flexibility between IaaS and PaaS resource automation to maximize productivity. Codified configurations handle cross-cutting orchestration, unlocking efficiency at any layer.

What is the difference between infrastructure as code terraform and pulumi?

Infrastructure as code (IaC) tools like Terraform and Pulumi enable developers to manage cloud infrastructure through code instead of manual processes. Both tools follow infrastructure as code principles but have some key differences:

Provisioning Approaches

Terraform uses a declarative approach to provision infrastructure - you describe the desired end state of infrastructure through HCL or JSON and Terraform figures out how to create it.

Pulumi takes an imperative approach - you write code in languages like JavaScript, TypeScript, Python, or Go to provision infrastructure. This allows more flexibility to leverage programming constructs.

State Management

Terraform maintains state to map real infrastructure to your Terraform configuration. If resources are created manually, Terraform state has to be updated to prevent drift.

Pulumi relies on programming languages so state is managed through code. Resources can be referenced without needing centralized state management.

Code Organization

Terraform configurations tend to grow in complexity over time. Workspaces and modules help organize infrastructure across files and directories.

Pulumi leverages packages and libraries from programming languages allowing more flexibility in structuring infrastructure as code projects.

So in summary - Pulumi's programming approach avoids needing to manually manage state when provisioning cloud infrastructure. But ultimately both tools can help streamline infrastructure as code workflows.

Understanding Terraform Infrastructure as Code

Terraform is a powerful infrastructure as code (IaC) tool that allows developers to define, provision, and manage infrastructure in a declarative configuration language. With Terraform, you describe your desired cloud architecture in easy-to-read definition files using its own syntax, which then gets interpreted to manage infrastructure components like networks, virtual machines, Kubernetes clusters, etc.

This approach brings numerous advantages over traditional infrastructure management:

Terraform Language: The Syntax of Infrastructure Automation

At the heart of Terraform is its configuration language - a declarative syntax for describing infrastructure components and their relationships. Some key aspects:

  • Resource blocks: Used to define components like compute instances, storage, networks. Supports all major cloud providers like AWS, Azure, GCP.
  • Input variables: Parameterize resource configurations for reusability and customization.
  • Output values: Expose data from resources to output them from Terraform state.
  • Modules: Encapsulate reusable, production-grade components as packages to promote reusability.

The Terraform language offers an intuitive way to model infrastructure architecture. Its readability empowers developers across skill levels to quickly grasp infrastructure relationships.

Eradicating Configuration Drift with Code

A key value proposition of Terraform is its management of your infrastructure's desired state. Terraform maintains this state and reconciles any drifts from the actual state in the cloud.

This prevents configuration drifts that happen when changes are made manually outside Terraform's purview. Such drifts make infrastructure fragile and opaque over time.

With Terraform managing desired state in code, infrastructure stays consistent as per developer intentions. This maintains resilience and transparency in the infrastructure lifecycle.

Change Management: A Version-Controlled Approach

Terraform enables a version-controlled approach to infrastructure change management. All infrastructure components reside in human-readable definition files that can integrate with VCS tools like Git.

This produces an immutable log of changes made over time. Teams can collaborate effectively by inspecting diffs, merging changes, and maintaining revision history.

Such VCS integration also facilitates change approval workflows. Infrastructure changes become transparent PRs that can be reviewed before applying to production.

Overall, Terraform unlocks infrastructure as code - a modern paradigm that brings DevOps agility, consistency, and safety to cloud architecture management. Its declarative language models infrastructure elegantly while its state management and VCS capabilities provide powerful DevOps advantages.


Leveraging Terraform Modules for Scalable Architectures

Terraform modules are reusable bundles of Terraform configuration code that help structure infrastructure as code (IaC) in a modular way. As organizations scale their cloud infrastructure, Terraform modules promote consistency, reduce duplication, and simplify management of complex architectures.

Reusable Code with Terraform Modules

Terraform modules encapsulate infrastructure components into reusable code packages. For example, you can create a networking module with VPCs, subnets, route tables etc. By parameterizing inputs and outputs, the same module can be reused across different environments like dev, test, and prod.

Some benefits of using Terraform modules include:

  • Simplified code: Abstract infrastructure code into small, focused modules that hide unnecessary details
  • Reusability: Leverage existing pre-built modules from the Terraform Registry instead of reinventing the wheel
  • Consistency: Standardize infrastructure patterns so they can be replicated easily
  • Encapsulation: Modules act as black boxes, reducing coding effort and complexity for developers

For example, to set up a reusable autoscaling group module:

variable "instance_type"{}
variable "min_size" {}
variable "max_size" {}

resource "aws_launch_configuration" "example" {
  # ...

resource "aws_autoscaling_group" "example" {
  launch_configuration =
  min_size = var.min_size
  max_size = var.max_size

  # ...

This abstracts away instance details, letting you reuse the same pattern across environments by simply tweaking the module's variables.

Automated Resource Deployment with Execution Plans

An incredibly powerful capability of Terraform is execution plans. An execution plan lets you preview changes before actually applying them.

This provides a "safety net" so you can:

  • Verify create, update, and destroy actions accurately reflect your intent before changes happen
  • Catch any unintended or dangerous changes to critical infrastructure
  • Share plans with your team to align on changes before applying

For example:

$ terraform plan 

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:  

  # aws_instance.web will be created
  + resource "aws_instance" "web" {
      + ami           = "ami-1234567"
      + instance_type = "t2.micro"

Plan: 1 to add, 0 to change, 0 to destroy.

This previews the AWS instance resource that will be created, enabling you to confirm the deployment parameters before Terraform actually provisions anything.

Using execution plans helps reduce manual errors and provides oversight for safer, more reliable infrastructure changes.

Infrastructure Dependency Mapping with Resource Graphs

As infrastructure grows in complexity, it can be challenging to track dependencies between resources. Terraform builds a dependency graph to show relationships between resources so you can visualize the connectivity.

In the Terraform UI, you can render graphs to map components like:

  • VPCs, subnets, route tables, security groups
  • Load balancers, autoscaling groups, compute instances
  • Databases, caches, object storage
  • IAM roles and permissions

Benefits include:

  • Understand dependencies - Identify cascading relationships upfront to prevent unexpected failures.
  • Plan changes - Determine order of resource creation/updates intelligently by analyzing graph links.
  • Refactor safely - Reshape graphs by decoupling resources without breaking connectivity.

Getting a bird's eye view of your infrastructure topology helps foster resilience and uptime by making component interdependencies transparent.

Overall, leveraging Terraform modules and capabilities like execution plans and resource graphs help tame infrastructure complexity. This allows developers to manage infrastructure-as-code more efficiently as system scale and team size grows.

Harnessing Multi-cloud Capabilities with Terraform

Terraform's versatility across major cloud providers makes it a powerful tool for managing multi-cloud strategies. Its infrastructure as code approach enables simplified provisioning and management of resources across AWS, Azure, Google Cloud Platform (GCP) and more.

Infrastructure as Code: AWS and Terraform Integration

  • Infrastructure testing: Teams can rapidly spin up temporary test environments with Terraform to validate application changes safely without impacting production infrastructure.
  • Cost optimization: Terraform makes it easier to manage idle infrastructure in Azure. Teams can identify and eliminate resources not being utilized fully.
  • Reusability: Modules enable creating standardized components that can be integrated across projects consistently. This improves efficiency while ensuring environment consistency.

By leveraging Terraform Azure modules, teams can maximize productivity and cost-efficiency when building cloud solutions on Azure.

Google Cloud Platform and Terraform Synergy

Together, GCP and Terraform provide robust infrastructure automation capabilities:

  • Simplified GCP resource provisioning: Terraform enables declarative infrastructure as code for creating GCP resources rapidly without manual effort. This boosts team productivity.
  • Built-in validation: Terraform validates configuration syntax and dependencies before provisioning GCP infrastructure. This prevents errors and unexpected outages.
  • Automated testing workflows: Teams can quickly spin up and tear down test environments in GCP with Terraform. This facilitates infrastructure testing without production impact.
  • Reusable infrastructure: GCP modules make Terraform configurations reusable across environments. Teams can build standardized platforms rapidly.

With GCP and Terraform, teams unlock productivity gains through reliable infrastructure automation across staging, testing and production environments.

By integrating Terraform with major cloud platforms like AWS, Azure and GCP, teams can harness true multi-cloud capabilities while benefiting from consistent, automated infrastructure provisioning. Terraform unlocks teams from manual processes and facilitates infrastructure testing, reuse and standardization across environments, boosting productivity and operational efficiency significantly.

Infusing Terraform into the DevOps Lifecycle

Terraform fits naturally within the DevOps paradigm, streamlining CI/CD pipelines and infrastructure management. By treating infrastructure as code, Terraform aligns perfectly with key DevOps principles like version control, testing, and automation.

Testing as a Pillar of Terraform Infrastructure

Testing is a critical pillar of robust Terraform infrastructure, guarding against unintended changes and configuration drift. Here are some key testing strategies:

  • Unit Tests: Validate individual Terraform modules and components in isolation to pinpoint issues. Mock dependencies for faster test runs.
  • Integration Tests: Assess interactions between modules by deploying a simplified stack. Helps catch integration errors early.
  • End-to-End Tests: Deploy the full stack to a test environment and run validation checks. Confirms production readiness.
  • Pre-Commit Hooks: Automatically run tests on infrastructure changes pre-commit to uncover problems immediately.
  • Linting: Static analysis of Terraform code catches formatting, deprecation, and security issues.

Comprehensive testing transforms infrastructure changes from nerve-wracking events to confident, mundane tasks.

Synergy with Configuration Management Tools

While Terraform excellently handles provisioning infrastructure, leveraging configuration management tools like Ansible, Puppet, or Chef to configure resources unlocks additional DevOps value:

  • Separation of Concerns: Terraform provisions; Ansible/Puppet/Chef configures. Clear responsibilities.
  • Idempotent Configuration: Tools guarantee configuration consistency and self-healing abilities.
  • Faster Convergence: Parallelizing Terraform resource creation and Ansible/Chef/Puppet configuration cuts lead time.

This best-of-breed approach harnesses the strengths of each tool for robust and speedy infrastructure management.

Seamless CI/CD Integration with Terraform

With proper integration, Terraform fortifies CI/CD pipelines by enabling infrastructure changes to flow through the same automated channels as application code changes. Popular options include:

  • GitOps: Mirror desired infrastructure state in Git. Terraform plans/applies happen via CI/CD upon merge.
  • Atlantis: GitOps workflow built on Terraform pull requests and automated policy enforcement.
  • Spinnaker: Multi-cloud CI/CD platform for release management. Terraform stages deploy infrastructure.

This eliminates slow, unreliable manual steps, ensuring infrastructure keeps pace with accelerating application release tempos.

Strategies for Cost-Effective Infrastructure with Terraform

Terraform empowers teams to codify and implement cost optimization best practices:

  • Right-sizing: Create modules that deploy just enough resources to meet SLAs. Simple to adjust sizing configs.
  • Auto-Scaling: Streamline scaling infrastructure up/down based on demand signals with Terraform's count meta-argument.
  • Spot Instances: Take advantage of significant EC2 savings by gracefully handling spot interruptions.
  • RI Utilization: Improve visibility into RI usage; prevent over-purchasing.
  • Unused Resource Identification: terraform state reveals orphaned resources to eliminate waste.

Infrastructure thriftiness directly boosts the bottom line. Teams increase velocity by not worrying about waste and overspending.

Security and Compliance: Terraform's Governance Features

Terraform's infrastructure as code approach enables organizations to implement robust governance practices for enhanced security and regulatory compliance. By codifying infrastructure, Terraform facilitates the enforcement of policies, access controls, change tracking, and drift detection critical for regulated environments.

Enforcing Policies as Code with Terraform

Terraform offers native integration with policy-as-code frameworks like HashiCorp Sentinel. Sentinel policies define guardrails and constraints over Terraform configurations, preventing unsafe actions like:

  • Deploying assets in prohibited regions
  • Using unapproved instance types
  • Opening insecure ports

By embedding policy checks into CI/CD pipelines, organizations can mandate infrastructure changes adhere to security best practices and compliance standards. For example:

policy "restrict-instance-size" {
  enforcement_level = "hard-mandatory"
  main = rule {
    all aws_instances.size == "t3.micro"

This Sentinel policy strictly limits AWS EC2 instances to the T3 Micro size, reducing costs.

Version Control System Integrations for Role-Based Access

Terraform natively integrates with version control systems like GitHub and GitLab. Organizations can scope user permissions to specific repositories and branches containing Terraform code.

For example, developers may have write access in lower environments while operators have exclusive production access. This facilitates a separation of duties, a core tenet of governance frameworks like SOC 2.

Achieving Regulatory Compliance through Codification

In regulated industries like healthcare and finance, organizations must adhere to complex compliance standards like HIPAA, PCI DSS, and SOX.

Terraform simplifies audit preparation by providing complete visibility and change tracking over infrastructure. Its state file logs all actions, enabling teams to quickly demonstrate compliance controls to auditors.

Further, codified infrastructure ensures consistency and reduces human error that often lead to misconfigurations flagged in audits.

Maintaining Synchronicity: Drift Detection and Remediation

Even with rigorous change control procedures, infrastructure still succumbs to "drift" over time as components are modified outside Terraform.

Terraform's drift detection capability scans cloud resources and identifies deviations from state. Teams can then remediate drift by either updating the Terraform configuration or destroying and recreating offending resources.

This ensures infrastructure remains in sync with its desired state per the Terraform code, critical for both security and compliance.

Embarking on the Terraform Journey: Best Practices and Tips

Adopting Terraform Gradually: A Pragmatic Approach

When first adopting Terraform, it's best to start small and manage non-critical infrastructure resources at the beginning. As teams gain proficiency, Terraform usage can be gradually expanded to more critical components.

For example, Terraform could be used to manage:

  • Non-production resources like staging environments
  • New pilot projects or minor applications
  • Small subsets of infrastructure rather than an entire architecture

This pragmatic approach reduces risk, builds organizational skills, and lays the foundation for smoothly scaling terraform infrastructure as code over time. Rushing into widespread Terraform adoption across critical systems can overwhelm teams still climbing the learning curve.

Beginning with peripheral resources allows for experimentation, knowledge growth, and gathering of best practices without severely impacting operations if mistakes occur. Infrastructure can be incrementally migrated to Terraform control as proficiency advances.

Effective Terraform State Management

With Terraform being used collaboratively by teams, proper state management is crucial for avoiding conflicts, errors, and issues. Utilizing a secure remote state store should be a priority.

We recommend using Terraform Cloud's built-in remote state management functionality. Benefits include:

  • Secure storage of state files
  • Locking mechanisms to prevent concurrent state file access
  • Versioning of all changes
  • Access controls and permissions

Robust remote state improves efficiency and reduces mistakes from poor state sharing. It's an essential pillar for successful team usage of infrastructure as code with Terraform.

DRY Principles in Terraform: Refactor and Reuse

The "Don't Repeat Yourself" (DRY) principle should be applied to Terraform code. When identical or similar provisioning logic is needed for multiple cloud resources, it's best to refactor that logic into reusable Terraform modules.

Modules abstract away common provisioning patterns, making configurations more maintainable. Teams can consume modules without worrying about the underlying implementation details. This reduces duplication and centralizes logic for easier updates.

Some examples of good module candidates:

  • VPC networks
  • Compute clusters
  • Database instances
  • Load balancers

See the Terraform Module Registry for quality community modules that can be referenced.

Fostering a Collaborative Terraform Community

While Terraform usage is ramping up internally, also encourage teams to engage with the broader open source community. Knowledge sharing and contributions ultimately lift all users.

Consider participating in forums like HashiCorp Discuss to exchange ideas and solutions. Contribute bug reports or fixes to Terraform GitHub. For modules, publish ones your team creates to the Module Registry for others to use.

This collaborative ethos aligns with the nature of infrastructure as code tooling. Strengthening community bonds will support your long-term Terraform goals.

Conclusion: Terraform's Role in Modern DevOps

Terraform has become an indispensable tool for infrastructure as code and enabling automated, efficient DevOps workflows.
