Each new feature should reside in its own branch, which can be pushed to the central repository for backup/collaboration. But, instead of branching off of master, feature branches use develop as their parent branch. When a feature is complete, it gets merged back into develop. Features should never interact directly with master.
The idea is to create a pipeline per branch. Each pipeline has a lifecycle that is tied to the branch. When a new, short-lived branch is created, we create the pipeline and required resources. After the short-lived branch is merged into develop, we clean up the pipeline and resources to avoid recurring costs.
