This boolean constraint requires buckets to use uniform bucket-level access where this constraint is set to True.

Any new bucket in the Organization resource must have uniform bucket-level access enabled, and no existing buckets in the organization resource can disable uniform bucket-level access.
Enforcement of this constraint is not retroactive: existing buckets with uniform bucket-level access disabled continue to have it disabled.

The default value for this constraint is False. Uniform bucket-level access disables the evaluation of ACLs assigned to Cloud Storage objects in the bucket.
Consequently, only IAM policies grant access to objects in these buckets.

Affected Resources:

Cloud Storage

In Solvay...

All resources IAM has to be audited.
Cloud Storage bucket provide the flexibility to provide folder level access.
In order to simplify auditing, all buckets have to implement uniform bucket-level access instead.

No exception will be allowed. All buckets will need to be bucket-level access.
