DevOps Essentials

We recommend the following knowledge:

• Basic knowledge of processes -and understanding -IT
• Reading English.

The DevOps movement believes there is a better way of building teams and software that has rapidly spread across the development and operations community. The culture of a DevOps organization and team is the heart of the movement and the most important pillar to implement. In this two day course you will explore the origins of the movement, the building blocks of Agile and Lean and the cultural changes you and your organization will need to adopt to become a successful DevOps team. In a blended mixture of theory, hands on, workshops and the use of tools such as Jenkins you will learn how to plan, organize and work in an atmosphere of collective responsibility.

This course provides an insight into the principles, added value and characteristics of DevOps.
