OverviewCommon automation toolsDifferent approachesThe Red Hat difference

Choosing theautomation solution that works best for your organization is no easy task. There’s not a single "right" approach—you can automate your enterprise in multiple ways. Indeed, many IT organizations today use more than one automation tool, and a major consideration is how well they work together to achieve business goals.  

Other factors to keep in mind when evaluating automation tools include architecture (is it agent-based or agentless?), programming (is it declarative or procedural?), and language (is it data-serialized or domain-specific?). And of course your operating system.  It’s also important to understand the level of community support for each product and what each is primarily engineered to do, such as provisioning, configuration management, and compliance.    

Clearly, there are many considerations when choosing an automation software for your business. This article helps explain the differences betweenRed Hat® Ansible® Automation Platform and other common open source automation tools.

Common open source automation tools

With open source at its core,Red Hat Ansible Automation Platform is asecurity-hardened, tested subscription product that offers full life cycle support for organizations. It’s built upon the foundation of its upstream project, Ansible, and benefits from the experience and intelligence of its thousands of global contributors.

So where does Ansible fit in the wider landscape of automation tools that includes Terraform, Puppet, Chef, and Salt?  Each of these products is supported and takes a distinct approach to automation, and all are available as enterprise solutions sold by different software companies.  

  • Terraform was created in 2014 by HashiCorp. 
  • Puppetis supported by Perforce and is available in a series of commercial products including Puppet Enterprise and Puppet Bolt.
  • Chef was acquired by Progress in 2020 and is available in a series of commercial products including Chef Enterprise Automation Stack. 
  • Salt(commercially known as SaltStack) was acquired by VMWare in 2020, to be included as part of the vRealize Automation portfolio that was recently rebranded as VMware Aria Automation. VMware was acquired by Broadcom in 2022.

Each tool approaches IT automation differently

Ansible

Known for its simplicity and ease of use, Ansible Automation Platform is an open source, command-line IT automation software application that usesYAML-based "playbooks" to configure systems, deploy software, andorchestrate advanced workflows to support application deployment, system updates, networking configuration and operation, and more. It does not require the installation of an agent on managed nodes, which simplifies the deployment process. And it has strong support for cloud-based infrastructure.

Terraform

Terraform is a cloud infrastructure provisioning and deprovisioning tool with an infrastructure as code (IaC)approach. It’s a specific tool with a specific purpose—provisioning. Like Ansible, it has an active open source community and well-supported downstream commercial products. And it has strengths that—when combined with Ansible Automation Platform—work well to create efficiencies for many businesses.

Puppet

Puppet is an automation application designed to manage large and complex infrastructures. By using a model-driven approach with imperative task execution and declarative language to define configurations, it can enforce consistency across a large number of systems. It also has strong reporting and monitoring capabilities, which can help IT teams identify and diagnose issues quickly.

Chef

Chef is an IT automation platform written in Ruby DSL that transforms infrastructure into code. Similar toAnsible Playbooks, Chef uses reusable definitions known as cookbooks and recipes (thus the product name) to automate how infrastructure is configured, deployed, and managed across networks—whether on-premise, in the cloud, or in a hybrid environment. It has strong support for testing and verification of configurations, which can help catch issues before they affect production systems.

Salt

 Salt is a modular automation application written in Python. Designed for high-speed data collection and execution, it’s aconfiguration management tool with a lightweight ZeroMQ messaging library and concurrency framework that establishes persistent Transmission Control Protocol (TCP) connections between the server and agents.
