Puppet is one of the long standing tools in the full-fledged configuration management space. It’s an open source tool, but given how long it’s been around, it has been well vetted and deployed in some of the biggest and most demanding environments. Puppet is based on Ruby, but uses a customized Domain Scripting Language (DSL) closer to JSON for working within it. It runs as a master-client setup and uses a model-driven approach. The Puppet code design works as a list of dependencies, which can make things easier or more confusing, depending on your setup.

When to use it: Puppet is a good choice if stability and maturity are key factors for you. It’s good for large enterprises with a heterogeneous environment and range of skills on the DevOps team.

Price: Puppet comes in a free open source version or a paid commercial enterprise version that runs $120 per node per year, with volume discounts.
