- <\/b>Basic roles, <\/b><\/strong>originally called primitive roles, are Owner, Editor, and Viewer. Each is extremely broad, an Editor can modify almost anything in a project, and they predate IAM entirely. Current guidance limits these to testing and sandbox environments, not production, since a compromised account holding a basic role has a very large blast radius.<\/li>\r\n
- <\/b>Predefined roles, <\/b><\/strong>maintained by Google for each specific service, are the recommended default for real work. Google’s own product teams define these based on the permissions a given job actually needs, and they update automatically as a service evolves, without you having to maintain anything yourself.<\/li>\r\n
- <\/b>Custom roles, <\/b><\/strong>which you build yourself from individual permissions, exist for the cases a predefined role does not cover precisely, either too broad or missing something specific. They take real ongoing maintenance, since Google does not update them for you as services change.<\/li>\r\n<\/ul>\r\n
The order to actually check them in is predefined first, custom only if nothing predefined truly fits, and basic roles reserved for throwaway testing.<\/p>\r\n

<\/figure>\r\n<\/div>\r\nWhat Actually Happens When You Delete a Custom Role<\/h2>\r\n
Deleting a custom role does not erase it immediately. It becomes soft deleted, and you have 7 days to undelete it if you change your mind, during which any existing bindings to it stop working but the role definition itself is still recoverable. After 7 days, it is permanently deleted and cannot be recovered, and any remaining bindings to it are removed entirely. Even after that, the specific role ID cannot be reused for a new role until roughly 30 days beyond the permanent deletion point, so if you need the exact same ID again soon, expect to wait.<\/p>\r\n
