Chef Infra vs Fabric

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.

Fabric is a free, open-source Python library for running shell commands remotely over SSH and returning Python objects. It supports individual hosts and multiple hosts, with serial or parallel execution, and can run Python functions or code blocks against those connections. Through Invoke, Fabric exposes Python tasks with parameters and pre- or post-tasks through the fab command-line tool; a comma-separated host list supports serial task execution. Paramiko supplies SSH protocol support, while documented authentication methods include private key files, SSH agents, and passwords. The installation guide recommends pip install fabric and lists Python, Invoke, and Paramiko as requirements. Fabric is available for Linux, macOS, and Windows in a self-hosted, agentless model. Its documentation says it adds no extra GSSAPI support beyond Paramiko’s connection parameters. Modern Fabric can be installed alongside Fabric 1 for a gradual upgrade. Each run or sudo call uses a separate remote shell session, so directory changes do not persist between calls.
