In Nutanix Self-Service,Projectsare the foundational organizational construct. Documentation states that Projects allow administrators to:
* Groupusers and user groups
* Assignroles(Consumer, Developer, Project Admin, etc.)
* Defineresources(clusters, networks, images) allocated to that project
* Attachblueprints, application profiles, and environments
