Abstract: Disclosed herein is a system for providing a test environment, composed of one or more virtual machines, to a developer instantly in response to a checkout request from the developer. To do this, a sandbox service implements a smart, tiered approach to creating and provisioning virtual machines that compose the test environments. The approach is flexible and elastic in nature, so that the developers do not have to wait an extended period of time for a test environment, yet the costs associated with configuring the virtual machines (e.g., storage and compute costs) are minimized. For example, the sandbox service can use historical data to predict a number of checkout requests expected for a first time interval (e.g., one day), a second time interval (e.g., thirty minutes), and a third time interval (e.g., five minutes). The sandbox service can then configure virtual machines into different states based on the predicted numbers.

Abstract: Aspects of the present disclosure relate to systems and methods for impersonating target user accounts via account redirection. In one aspect, a request may be received at a service issued from a temporary account of the service accessed by a client application. It may be determined whether the temporary account is stored in a mapping table comprising one or more temporary accounts mapped to a corresponding impersonation token. When it is determined that the temporary account is stored in the mapping table, the corresponding impersonation token mapped to the temporary account may be identified. The request may be processed in an impersonation mode based on the identified impersonation token.

Abstract: A visitor to a profile page is invited to modify a user profile associated with the profile page. If the visitor elects to provide a suggested modification to the profile page, a message is transmitted to the user that owns the profile page requesting authorization to perform the suggested modification. In response to the message, the user can accept the suggested modification to the user profile, decline the suggested modification to the user profile, or edit the suggested modification to the user profile. If the user accepts or edits the suggested modification to the user profile, the user profile is modified accordingly. In this manner, a visitor to a profile page can assist in the creation of a user profile.
