Navigating IAC: A Guide To The 22 Best Tools Of 2025
10 Best IAC Tools Shortlist
Here's my pick of the 10 best software from the 22 tools reviewed.
Our one-on-one guidance will help you find the perfect fit.
As someone who has navigated the ins and outs of infrastructure management, I fully appreciate the pain points you're likely experiencing. Modern software development requires managing a lot of moving parts - dependencies, cloud resources, on-premises hardware, operating systems, and the list goes on.
Tools like Amazon's CLI, Microsoft's Azure Resource Manager, and others on GitHub have become indispensable. They help provision infrastructure across cloud environments and handle the automation necessary for efficient software delivery.
Let's talk about Infrastructure as Code (IAC) tools - they transform infrastructure configuration into source code. I can't overstate how transformative this is; it enables automation of infrastructure deployments, making them as manageable as version-controlled code.
Need expert help selecting the right tool?
With one-on-one help, we guide you to your top software options. Narrow down your software search & make a confident choice.
We can use familiar programming languages like Ruby, JavaScript, or TypeScript, or domain-specific languages (DSL) like HashiCorp Configuration Language.
These tools, some of which are becoming quite popular, allow us to declare our infrastructure requirements, and they create and manage the necessary cloud resources or virtual machines to meet those requirements.
We can set up dependencies, manage different operating systems, and create SSH keys all with code, reducing the risk of manual errors. This declarative approach to defining our infrastructure is the game changer, as it assures the state of our systems matches our source code declarations.
This is why you'll want to seriously consider the IAC options I'm going to share.
What Are IAC Tools?
Infrastructure as Code (IAC) tools are digital powerhouses, transforming the way technology practitioners manage and provision their IT resources. At their core, these tools allow IT infrastructure to be managed programmatically, making the entire process more efficient, repeatable, and secure. IAC tools are favored by system administrators, developers, and DevOps professionals who strive to automate the setup, deployment, and management of servers and networks.
They're used to maintain consistency across different environments, speed up deployment times, and minimize potential human error during configuration. Whether you're managing a small-scale project or a large, complex system, IAC tools offer a way to streamline operations and drive high-performing digital environments.
