US Patent 9356883 Allocating cloud-hosted application resources using end-user metrics

At least one workflow comprising end-user interactions with an application implemented using provider network resources is identified by a resource allocation service of the provider network. The service collects performance metrics associated with the end-user workflow. If a performance metric meets a threshold criterion, a re-evaluation of the resources assigned to the application is initiated. Configuration changes to modify the set of provider network resources assigned to the application are implemented in accordance with a result of the resource re-evaluation.
