cdist vs Chef Infra

cdist is a free, open-source configuration management system that applies a defined state to computers through shell scripts and cdist types. It is positioned as an alternative to Ansible, Chef, and Puppet. Types provide the extension mechanism, and the project says their results are idempotent, so outcomes do not depend on call order. cdist uses push mode: source computers connect to targets over SSH and apply configuration, without requiring a central server or an agent on the target. A target needs a POSIX-compatible shell and SSH server, while the source needs a POSIX-like shell, Python 3.5 or later, and an SSH client. The project lists a small core, standard types, and parallel execution. Installation is documented through Git or pip. Supported systems include Linux distributions, BSD systems, Mac OS X, and XenServer. Manuals are available in HTML and man-page formats, with community help through Matrix and IRC.

Chef Infra automates infrastructure configuration and helps keep systems aligned with a defined desired state. Teams express configurations and policies as code, test them, and deliver them through automated pipelines; Chef Infra can correct configuration drift when systems diverge. It supports Windows and Linux systems, cloud ARM systems, and Mac laptops across on-premises, cloud, and edge environments. Chef Infra Client includes more than 150 resources, while the community provides thousands of configuration templates. Chef Workstation bundles the client with Chef InSpec, Chef Habitat, Test Kitchen, Cookstyle, and Chef Upgrade Lab. The policy language is Ruby DSL, and listed capabilities include policy testing, reporting, and CI/CD integration. The free community version is non-commercial. Business costs $59 a year per node, and Enterprise costs $189 a year per node; Enterprise Plus requires a customized quote. Chef Infra Client 19.x is listed as the current LTS release, while 18.x is deprecated and earlier versions are end of life.
