Infrastructure as Code (IaC) has transformed how organizations provision and manage their IT infrastructure. In this article, we will review some of the most useful IaC tools for your business in 2025.

What is IaC?

IaC treats all infrastructure pieces as code, using different programming languages or tools. By codifying infrastructure, IaC allows for automation, consistency, and repeatable processes in deploying and managing resources. This approach not only reduces human error but also enhances efficiency and scalability.

What are Infrastructure as Code tools?

IaC tools are software solutions that enable the automation of infrastructure provisioning and management. They use code to automate the setup and configuration of IT resources, making it easier to manage large-scale, complex, and dynamic environments.

Why should you use IaC Tools?

Infrastructure as Code tools and frameworks bring several benefits, including:

  • Speed and Efficiency: Automated processes reduce the time required for provisioning and managing infrastructure.
  • Consistency and Accuracy: Code-based management minimizes human error, ensuring a more consistent environment.
  • Scalability and Flexibility: Large-scale infrastructure is easier to manage, and adaptation to changes is quicker.
  • Version Control and Documentation: Infrastructure changes are tracked, providing an audit trail and documentation.

Key points

IaC is critical in modern IT operations, ensuring speed, efficiency, and accuracy in infrastructure management. Each of the range of IaC solutions available has unique features, catering to different environments and requirements.

These best Infrastructure as Code tools work well on their own, but the extra layer of orchestration that a platform like Spacelift provides allows you to handle them at scale and enhance the collaboration between your team members.
