Software developers and project managers can use infrastructure as code (IaC) software to automate the management and provisioning of infrastructure. By bypassing manual configuration, software development teams can enjoy lower costs, faster speed, and fewer errors. This guide will discuss the following infrastructure as code tools in terms of their features, pros, cons and pricing so you can pick the ideal solution for your needs:
- Puppet: A great option for teams seeking IaC software that can handle large-scale infrastructure and also has an established and supportive community.
- Chef: An excellent pick for developers seeking a flexible and advanced configuration management tool that relies on infrastructure as code to automate complex tasks.
- Terraform: An ideal solution for development teams seeking an open-source IaC tool for cloud-based environments.
Puppet is an IaC tool that uses its own declarative language to define desired infrastructure states. It has a solid interface and reporting capabilities and is ideal for teams and organizations in charge of managing large-scale infrastructures.
Features of Puppet
Some of Puppet’s features that have made it a popular DevOps tool include:
- Multi-platform support.
- Real-time monitoring.
- Third-party integrations.
Puppet supports multiple platforms, including Windows, Linux, Microsoft Azure, AWS, GCP and more. The IaC software has real-time monitoring and reporting to help developers spot drift and compliance errors. It also leverages policy-as-code for streamlining and enforcing compliance. You can also extend Puppet’s functionality by integrating it with third-party cloud, infrastructure, secret management, policy-as-code and other services.

Pros of Puppet
Puppet’s pros include:
- Well-established community.
- Fast error fixes.
- Learnable language.
- Intuitive interface.
Since Puppet has been around since 2005, it has a large, well-established community that can offer support and resources for new users and those who stumble upon obstacles. Puppet highlights lines containing coding errors so they can be fixed quickly.
While Puppet’s use of its own declarative scripting language (DSL) can be a con for some newer users, the language is at least easy to learn and eventually write. Puppet’s user interface is also clean and easy to follow.
Cons of Puppet
Puppet’s cons include:
- Can be complicated to configure.
- Complexity – known for its steep learning curve.
- Requires some programming knowledge.
Setting up Puppet can take some time and patience and requires users to be more hands-on than some simpler competing tools since it was designed more for system administrators than less technical users.
Puppet has a steep learning curve, and unless you have a programming background and knowledge of the Puppet DSL, you may have a hard time adapting to it. Additionally, since Puppet only has two versions, some teams may find the custom Enterprise pricing prohibitive if they want more advanced features.
Project managers and developers can choose between Open-Source Puppet and Puppet Enterprise. The open-source version is free.
Puppet offers the Enterprise version via custom-priced plans. It comes with automation features, extensions and more. Get a custom Puppet Enterprise pricing quote.
Progress Chef (formerly Chef) is a flexible configuration management tool with a large following that uses infrastructure as code. It is used by software developers, DevOps teams, system administrators and more to automate their infrastructure and applications’ configuration management.
Features of Chef
Chef has several features that make it a popular DevOps tool, including:
- IaC features and adherence.
- Recipes and cookbooks.
- Chef Supermarket.
- Integrations with third-party DevOps tools.
Chef is a platform-agnostic programmer tool due to its system resource abstraction, allowing it to support different cloud platforms and operating systems. Due to its reliance on infrastructure as code, Chef keeps configuration consistent and repeatable and promotes version control via a host of version control tools.
Staying in line with the “Chef” name, the IaC tool relies on recipes and cookbooks. Recipes are specific actions/configurations, while cookbooks are recipe collections. Chef’s recipes and cookbooks keep configuration management simple for developers by letting them reuse code and embrace the power of modularity.
The Chef Supermarket is loaded with pre-built cookbooks to speed up configuration management. There is also a large community ecosystem that supplies users with best practices, cookbooks, modules and more. Chef is highly extensible, too, thanks to third-party integrations with Jenkins, CircleCI and other popular tools.
Pros of Chef
Some of Chef’s biggest advantages as an IaC tool include:
- Advanced configuration management capabilities.
- Community support.
- Versatile, offering greater control of configurations.
Some of Chef’s competition is best served for handling basic tasks. Chef, on the other hand, has advanced configuration management features to handle complex tasks, such as test driven development infrastructure deployment on-demand. Progress Chef also excels in extensibility as the programmer tool integrates with top DevOps tools like CircleCI, Jenkins, Bitbucket, GitHub and more.
If you are looking for an infrastructure as code tool with a large community that offers added support and resources, you will find just that with Chef. And if you are looking for an IaC tool that is flexible so you have more configuration control, Chef offers that, too, since it follows a code-driven approach.
Cons of Chef
Chef could improve in some areas as a developer tool, such as:
- Required experience level.
- Time investment.
- Expensive for small teams.
Yes, Chef was built to handle even the most complex tasks. But to unlock that functionality, you will face a steep learning curve. Remember that Chef was created with experienced programmers in mind, so it will take some time to learn. One thing that could help is taking a Ruby course prior to tackling Chef. Beyond the complexity obstacle, you may find Chef pricey, especially if you are part of a smaller development team with a limited budget.
Pricing of Chef
Developers can buy Chef directly through Progress or via a marketplace. Buy the IaC tool from Progress, and you can get a custom quote for the SaaS or on-premise option. Buy Chef from the Azure Marketplace, and you get three options:
