Azure Automation vs Chef Infra

Azure Automation is a cloud service for process automation, configuration management, patch management, and remediation automation on Windows and Linux. Process automation is divided into job run time and watchers: the job run time plan includes 500 minutes per month, while the watchers plan is listed at free with 744 hours included monthly. Configuration management has separate Azure-node and non-Azure-node plans. The Azure-node option includes a configuration pull service and change tracking; the non-Azure-node option includes five nodes per month. An Update management plan lists update visibility and update deployment. These options cover automating processes, managing configuration, and handling updates across both supported operating systems. Azure Automation uses a cloud deployment model. The pricing model is listed as freemium, although the facts also state there is no free plan.

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.
