In some embodiments, services and resources may be assigned to more than one additional resource container. For example, the VM 228 may not only be assigned to ProjectPhobos, but also to a ProjectDeimos (not pictured) resource container, which may be shared with additional customer C (also not pictured). In this example, the additional customer C may have a separate account (e.g., Account 789) with the computing resource service provider from the accounts of the customer A 202A and the customer B 202B (e.g., lacking access to Account 123 and Account 456, respectively). Consequently, customer A 202A may not have access to the ProjectDeimos resources, other than those that may already be accessible either through ProjectPhobos or already associated with Account 123 of customer A 202A. However, because the VM 228 in this example is associated with both ProjectPhobos and ProjectDeimos, the VM 228 may be accessible to each of the customers A 202A, B 202B, and C. However, in this example, the table 224 is not associated with ProjectDeimos, and consequently the additional customer C may be denied access to the table 224.
