A database management system for managing a database includes each document being stored as a number of replicas for accessibility and data preservation. The system includes: a processor; a network interface; and a memory comprising programming instructions for execution by the processor to implement a database management service, the service configured to maintain a primary replica of a document, a number of secondary replicas of the document, and another log-only replica storing a log of changes to the document rather than contents of the document. The service makes head reads to the primary replica as needed when a read request to the number of secondary replicas does not result in a quorum.

Document database system using replicas of a stored document

A policy management service receives a request to associate a version of a computing resource policy as a default version of the policy. In response to the request, the service identifies, from a policy database, an entry for the default version of the policy. The service updates the entry in order to associate the version specified in the request as the default version of the policy. This results in the version of the policy becoming applicable to control access to the computing resources associated with principals associated with the default version of the policy.

Sharing of computing resource policies

A security token service receives a request for a token. The request indicates a set of access control policies that define a set of permissions for access to a resource. The security token service generates the token to comprise a set of identifiers of the set of access control policies. The security token service provides the token in response to the request to enable the token to be used to access the resource in accordance with the set of access control policies.
