HI! Is there a good slideshow or videos somewhere that would explain the different components of Pulumi: what exactly is project, stack (micro-stack), etc. I would be interested in such a solution, where the infrastructure is managed by more than one team - lets say that team A manage only network stack, team B databases and how to use all this logic together with GitLab CI/CD (flow) without the Pulum cloud capabilities.

It’s not a slideshow or a video, but this series of blog posts (start with part 1 at https://www.pulumi.com/blog/iac-recommended-practices-code-organization-and-stacks/) may be helpful in this situation. In particular, the third post (on structuring projects) and the fourth post (on using stack references) may be especially applicable.
