Eclipse Sirius is a successful open-source project that has already been adopted worldwide on multiple different engineering domains: healthcare, space, energy, insurance, and so many more… With the advent of its Web version, numerous new use-cases are going to emerge. The game changer is the possibility to define a new DSL and its graphical syntax directly in the Cloud, and the ease to give access to rich studios to end-users directly from their web browser. In this talk we will show which concrete use-cases are already enabled by the current version and how they can be deployed on operational projects with Obeo Cloud Platform, the product that extends Sirius Web with additional collaborative and access control features. If you are new to Eclipse Modeling, or to Cloud technologies (or both), we will also present how we can accompany you on your projects, at your own pace, from a proof-of-concept up to an industrial deployment.
