DevOps Foundation case studies
DevOps Foundation · Put your knowledge to work in context.
The DevOps Foundation certificate is an entry-level credential for anyone who needs a shared, practical vocabulary for DevOps - developers, operations and support staff, testers, project and product managers, and business stakeholders working in or alongside a delivery team. It is a foundations-level exam rather than a hands-on engineering test: it checks whether you understand why DevOps exists and how its principles connect, not whether you can build a pipeline unaided. The syllabus is organised around six areas: DevOps introduction and purpose; culture and behaviour; practices such as flow, Lean, Agile and continuous delivery; automation and technology; measurement, metrics and reporting; and sharing, feedback and continuous improvement. Preparation works best in layers - learn the purpose and vocabulary first, then the practices, then how automation and metrics support them - and consolidate with practice questions that force you to distinguish closely related terms. The DevOps Foundation case studies are 5 cases and about 4,103 words.
