Top 10 Infrastructure as Code Tools

Ever wish you could snap your fingers and have your infrastructure magically provisioned and configured? While that’s a job for a magician, there is a real-world alternative that is (almost) as fast and miraculous – Infrastructure as Code (IaC).

With 68% of DevOps teams already using IaC, it’s clear this magic is real. Yet, IaC tools can be challenging to get to grips with if you are new to these types of applications, and choosing the right one can be the difference between mastery and confusion. 

What are infrastructure as code tools?

Infrastructure as Code (IaC) tools are software applications that manage and provision IT infrastructure through machine-readable definition files, replacing manual processes. This codified approach enables the automation of infrastructure provisioning, configuration, and management throughout its entire lifecycle.

By abstracting infrastructure into code, IaC offers several advantages:

• Automation: Eliminates manual intervention, reducing human error and accelerating deployment times.
• Consistency: Ensures identical environments across development, testing, and production, minimizing configuration drift.
• Scalability: Facilitates the effortless scaling of resources to match demand.
• Collaboration: Provides a shared, version-controlled repository of infrastructure configurations for enhanced teamwork.

Declarative vs imperative IaC

Declarative IaC focuses on the ‘what’ (desired state), while imperative IaC describes the ‘how’ (specific steps). Declarative IaC excels in managing complex infrastructure, while imperative IaC provides control over individual actions. Here’s a quick comparison between declarative and imperative IaC.

Feature	Declarative IaC	Imperative IaC
Focus	Defines the desired end state of the infrastructure.	Specifies the step-by-step actions to achieve the desired state.
Tool Examples	Terraform, AWS CloudFormation	Ansible, Chef
Idempotency	High: Re-running the configuration consistently results in the same infrastructure state.	Lower: Requires careful management of state and order of operations to ensure consistency.
Configuration	Usually more concise and readable.	Often more verbose and detailed.
Flexibility	Offers greater flexibility in how the desired state is achieved.	Provides more granular control over the exact steps taken during provisioning.
Use Cases	Ideal for managing large and complex infrastructure where a consistent state is crucial.	Well-suited for ad-hoc tasks, configuration management, and scenarios requiring precise control over the provisioning process.

Types of Infrastructure as Code Tools

Infrastructure as Code (IaC) tools encompass several categories, each catering to specific aspects of infrastructure management:

1. Configuration Management Tools: These tools specialize in automating the configuration of software and systems on existing infrastructure. They maintain consistency across environments, ensuring desired configurations are enforced and maintained.
2. Provisioning Tools: Provisioning tools handle the initial creation of infrastructure resources, such as virtual machines, networks, and storage. They automate resource allocation, freeing engineers from manual setup tasks.
3. Orchestration Tools: Coordinate complex workflows and dependencies between different infrastructure components. They manage the order and timing of operations to ensure a smooth and reliable deployment process.
4. Server Templating Tools: Server templates streamline the creation of standardized server configurations. By defining a baseline template, these tools ensure consistency across multiple servers, saving time and minimizing errors in manual setups.

Benefits of infrastructure as code tools

Increased Speed and Efficiency 

IaC automates the provisioning and configuration of infrastructure, drastically reducing manual effort and accelerating deployment times. This agility enables faster response to changing business needs.

Improved Consistency and Reliability

IaC ensures infrastructure is provisioned consistently across environments, minimizing configuration drift and reducing the risk of human errors. This consistency translates to more reliable and predictable system behavior.

Enhanced Collaboration

IaC enables version control and collaboration on infrastructure configurations, facilitating better communication and teamwork between development, operations, and security teams.

Scalability and Cost Optimization

IaC simplifies scaling infrastructure resources up or down to match demand, ensuring optimal resource utilization and cost efficiency.

Disaster Recovery

IaC configurations serve as documentation and blueprints, allowing faster and more reliable recovery in case of system failures or outages.

Key features to look for in an infrastructure as code tool

1. Declarative Language Support

A robust declarative language allows you to define the desired state of your infrastructure without specifying the exact steps to achieve it. It simplifies code, enhances readability, and minimizes errors. Look for tools that support popular declarative languages like HashiCorp Configuration Language (HCL), YAML, or domain-specific languages tailored for infrastructure. 

For example, Control Plane caters to different preferences by offering APIs and CLIs for those who prefer imperative commands alongside a user-friendly YAML specification for a more declarative approach. 

2. Modularity and Reusability

Creating and reusing modules or components promotes code maintainability and consistency across different environments. This feature streamlines infrastructure management, reduces redundancy, and accelerates deployment.

3. State Management

Effective state management is crucial for tracking the actual state of your deployed infrastructure. Choose tools with robust mechanisms for storing, querying, and reconciling state information to prevent configuration drift and ensure accurate deployments.

4. Integration with CI/CD Pipelines

Seamless integration with CI/CD pipelines enables automated infrastructure provisioning as part of your software delivery process. This feature accelerates release cycles, improves collaboration, and ensures consistent environments throughout the development lifecycle.

5. Cloud-Agnostic or Multi-Cloud Support

Depending on your infrastructure strategy, consider either cloud-agnostic tools (supporting multiple cloud providers) or offer robust support for your chosen cloud platform. This flexibility allows you to adopt the best tool for your needs and avoid vendor lock-in.

For example, many SaaS providers offer great solutions like Internal Developer Platforms (IDPs), yet they often push customers into their proprietary model, increasing the risk of vendor lock-in. In contrast, you can consider more flexible platforms like Control Plane, which adopts and provides open source IaC through Terraform and Pulumi. In this instance, you can do everything through the Control Plane CLI.
