Don't let this gap widen
Without Puppet mastery, manual IT infrastructure management produces inconsistent configurations and uncontrolled drifts.
75 % of major server incidents stem from these human errors, costing an average of 40 000 € per downtime and 8 hours of emergency work per administrator.
Your company suffers 25 % productivity losses and regulatory non-compliance risks, while your career stagnates against automated DevOps.
Every month without automation equals 10 000 € in lost time and increased vulnerability to cyber threats.
Presentation of the infrastructure as code concept. History of Puppet and positioning in the DevOps ecosystem. Puppet architecture: Master, Agent, Catalog, reports. Installation of Puppet on different OS. Discovery of the management console. Creation of first manifests: resources, classes, nodes.
Organization and structuring of Puppet modules. Use of ERB templates. Intelligent parameterization with Hiera. Management of multi-platform environments. Implementation of centralized configuration management. Practical examples: installation and configuration of services (Apache, MySQL...), user management, custom scripts.
Implementation of security rules (hiera-eyaml, secret management). Puppet development best practices (version control, publications on Puppet Forge). Testing, debugging, and validation of manifests. Resolution of common errors, report analysis. Infrastructure lifecycle management. Concrete case study: complete automation of a company infrastructure.
The Mastering Puppet: Automation and IT Infrastructure Management program is delivered onsite or remote (blended-learning, virtual classroom, remote presence).

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
