1. A computer-implemented method comprising: providing, by one or more configured computing systems implementing a computer infrastructure services provider having a plurality of objects for use by multiple users of the computer infrastructure services provider, a first object from the plurality for use by a user of the multiple users, wherein the first object has a first object identifier and is a type of computing resource; receiving, by the one or more configured computing systems, input from the user that includes one or more parameters and that does not include a first user-specified tag that is associated with the first object, wherein the first user-specified tag defines management activities for the computer infrastructure services provider to perform on the first object for the user; retrieving, by the one or more configured computing systems and based on the received user input, stored information that includes at least the first object identifier for the first object and a second object identifier for a second object not associated with the first user-specified tag, and that further associates the first object and the first user-specified tag; and performing, by the one or more configured computing systems and based at least in part on the first object being associated with the first user-specified tag in the stored information, an action on the first object for the user that is part of the management activities of the computing infrastructure services provider defined by the first user-specified tag, and not performing the action on the second object based at least in part on the second object not being associated with the first user-specified tag, wherein the performing of the action includes one or more of: classifying one or more instances of the first object in a specified manner; or encrypting one or more instances of the first object; or terminating one or more instances of the first object; or migrating one or more instances of the first object to a storage location.
