With bucket policies, you allow or deny an action to a resource in a bucket. You can also define conditions within a policy.

Bucket policies consist of policy statements and are limited to 20 KB in size. You can create a single policy per bucket, but you can add multiple statements to a single policy.

Bucket policies use a JSON-based language. See Policies and Permissions in Amazon S3 .

VMware Cloud Director Object Storage Extension provides a policy editor that you can use instead of the JSON editor.
