15 Best Infrastructure As Code Tools In 2024
Best Infrastructure As Code Tools Shortlist
Here are my top 12 Infrastructure as Code tools for different uses, evaluated on scalability, security, and other key features.
Our one-on-one guidance will help you find the perfect fit.
To streamline your infrastructure management, consider using Infrastructure as Code tools for benefits such as automated configuration, enforced consistency, decreased security risks, and increased productivity.
What Are Infrastructure As Code Tools?
Infrastructure as Code tools set up infrastructure resources such as networks and virtual machines through configuration files. This is in contrast to legacy methods, in which teams would manually set up physical servers and virtual machines and provision cloud computing.
By using code-based deployment of infrastructure, IaC enables automatic deployment instead of manual deployment, saving setup time. The use of code for the infrastructure layer also enables infrastructure versioning, akin to versioning in source code elsewhere.
Another major advantage of IaC is that it simplifies your network by enforcing consistency. This helps you avoid “snowflake” environments in which individual machines diverge into unique configurations over time. Because the IaC code runs the same way every time you execute it, you can remove system inconsistencies and keep every instance the same, which simplifies other tasks like troubleshooting and application deployment.

Other Options
I came across a couple of other highly beneficial Infrastructure as Code tools that are worth having a look at, even if they didn’t make the cut for the top 10 list:
Selection Criteria For Infrastructure as Code Tools
Here’s are the selection and evaluation criteria I used to narrow down my selections for best Infrastructure as Code tools:
Core Functionality
I started by looking at Infrastructure as Code tools that had core functionalities like:
- Automating infrastructure deployment, configuration, and management tasks
- Scaling your infrastructure resources up or down
- Granular control of infrastructure configurations
- Consistent results in delivering the desired environment
Key Features
Here are a few other necessary features needed to deliver the core functionalities listed above:
- Declarative syntax: This allows you to define infrastructure resources as code in a structured way, based on the endpoints you wish to reach. This increases readability and reduces human error.
- Version control: Infrastructure commonly goes through a lot of changes over time. Version control allows you to track your changes and even revert to a previous version if needed.
- Multi-cloud management: This feature allows you to use the Infrastructure as Code tools to manage multiple cloud providers, increasing flexibility and scalability.
Cost
I chose the best value-for-money tools to ensure you’re getting a good return on your investment. Some tools provide a free and enterprise edition, with the enterprise edition providing numerous features that aren’t available in the free version. Other tools have a pay-as-you-go model, where you only pay for the resources you use.
Scalability
I’ve looked for tools that scale with your infrastructure. I took note of which tools are better at scaling up with multiple cloud providers, and which are more specialized for scaling with a particular resource type.
Security
For this criteria, I’ve looked for features such as granular access controls to help reduce the number of unauthorized actions, as well as the ability to enforce any relevant compliance and security settings at the infrastructure level.
Integration
Infrastructure as Code tools require an API to integrate other external systems, enabling you to create more holistic workflows and processes. Because IaC tools are used in a cloud-native ecosystem, they should engage well with all of your existing and future platforms.
People Also Ask
Here are answers to commonly asked questions about Infrastructure as Code tools:
What is the most commonly used Infrastructure as Code tool?
Terraform is the most popular Infrastructure as Code tool for many reasons. One is multi-cloud support, meaning you can manage infrastructure resources across multiple cloud providers such as Google and Azure.
Terraform is highly effective for managing your network infrastructure and automating the creation of cloud infrastructure. Even if you’re working with a massive infrastructure environment, Terraform works well for managing many resources at once.
What are the three main categories in Infrastructure as Code tools?
There are three main categories of Infrastructure as Code tools based on the phases of the deployment process.
Configuration management includes tools for managing software and applications that run on provisioned infrastructure resources.
Infrastructure provisioning is another category, which includes tools that automate the process of provisioning infrastructure resources. These tools allow you to define infrastructure resources as code.
The last category is application deployment. These tools can deploy and manage applications on provisioned infrastructure. These help with deploying applications as code, making scalability more manageable.
What languages do Infrastructure as Code tools use?
There’s a whole range of languages used in Infrastructure as Code tools. Each tool uses different languages, depending on the specialty it’s designed for. For example, HashiCorp developed HashiCorp Configuration Language (HCL), which they use in Terraform.
JSON and YAML are often used to help automate infrastructure management. Some more general examples include Python and Ruby.
Finding The Right Tool
Infrastructure as Code tools have changed how teams run their infrastructure, but that doesn’t make it easy to choose the right one. A large enterprise might find more value in the robust offerings of an established provider, while a budget-strapped startup may prefer to look at free, open-source options. Consider each tool listed in this article, and decide which best suits your needs based on their strengths. There are plenty of great IaC options on the market, and I hope this list helps you narrow down your choices.
