Abstract: Configurations of computing resources established in a network-based computing service can be tested to assess impacts of proposed changes to the configuration states of the computing resources or to policies governing the configurations of such computing resources. Test environments can be established to simulate an operational computing environment under study. Changes to the configuration of one or more computing resources can be introduced to the test environment, and impacts to the test environment can be assessed. Changes to configuration policy can also be introduced and subsequent impacts can be observed.

Abstract: A configuration history service for web-based computing resources is implemented by capturing and storing a historical record of each configuration state for each computing resource in a subscriber's account. Files of the configuration history store information about a computing resource type offered by the web service. The file comprises records for each particular resource of that type that is or was actively configured in the subscriber's account during the period that the configuration history service is active in the account. Each record lists a particular configuration state, at a particular point in time, for a particular computing resource. The configuration history of a computing resource can be displayed as a timeline by which a subscriber can access information describing the configuration state of the particular computing resource at any point in time.

Abstract: Configurations of computing resources established on a web-based computing service can be monitored, managed and controlled. According to one embodiment, a method may include discovering a set of computing resources being used by an enterprise. The disclosed resource configuration service can deliver a set of resource-specific data that uniquely identifies each computing resource and describes each resource's configuration state. The resource configuration service monitors the computing environment and detects changes to the configurations of computing resources. The resource configuration service can deliver a stream of notifications when computing resources are created, updated, deleted or otherwise reconfigured. The notifications can be used by, for example, software tools or system administrators.

Abstract: Configurations of computing resources established on a web-based computing service can be monitored, managed and controlled. According to an embodiment, a configuration compliance service is implemented. Policy rules governing attributes of configuration states for computing resources in a subscriber's account are defined. The computing resources in the account are monitored for changes to configuration states. In response to detection of a change to a configuration state that violates a rule, a predefined action is taken. The predefined action can include sending a notification to the subscriber's account, reconfiguring the configuration state of the computing resource, and deactivating the computing resource.
