Chef Infrastructure Automation

Chef is a configuration management tool and infrastructure as code platform that automates the deployment and management of infrastructure across physical, virtual, cloud, and container environments. Founded in 2008 by Adam Jacob in Seattle, Chef Software (formerly Opscode) was acquired by Progress Software in 2020 for approximately 220 million USD. Chef serves over 1,000 enterprise customers including Meta, Target, and Capital One. Key features: Chef Infra (agent-based configuration management using Ruby-based DSL recipes and cookbooks that define desired system state, with idempotent execution ensuring systems converge to declared state on every run). Chef cookbooks (versioned collections of recipes, attributes, templates, files, and custom resources, shared via Chef Supermarket with over 3,000 community cookbooks). Chef Infra Client (runs on each managed node, periodically pulling and applying cookbook updates from Chef Infra Server, with detailed run reports and converged state tracking). Chef Infra Server (central hub storing cookbooks, node data, and policy, with role-based access control and high availability clustering). Chef Workstation (development tools including Chef Infra Client for local testing, Test Kitchen for integration testing, Cookstyle linting, and ChefSpec for unit testing). Chef Habitat (application automation and packaging tool that builds, deploys, and manages applications in containers, VMs, or bare metal with supervisors for lifecycle management). Chef InSpec (compliance as code framework with human-readable profiles for security and compliance testing against CIS, HIPAA, and PCI-DSS baselines). Chef Automate (unified visibility platform providing configuration management dashboards, compliance reporting, and infrastructure analytics). Ohai (system profiling tool that collects platform, network, hardware, and cloud metadata for use in cookbooks).
