Abstract: The application describes an authentication process that incorporates voice commands with an HTTP interface module to perform a multifactor authentication (MFA) process. For example, a first computer system may initiate the MFA process by sending, with a HTTP interface module maintained by the first computer system, a request to initiate the MFA process to the second computer system. The MFA process may also transmit an one-time password (OTP) to a first user device. The first computer system may receive an audible recitation of the OTP from a second user device. The OTP may be parsed and used to generate an HTTP request. The HTTP interface module may send the HTTP request to the second computer system. When the second computer system authenticates the user based at least in part on the non-audible file, the first computer system may receive confirmation of authentication of the user to initiate the transaction.

Abstract: Techniques are described for managing program execution capacity used to execute software programs, such as for a group of computing nodes in use executing one or more programs for a user. Dynamic modifications to the program execution capacity of the group may include adding or removing computing nodes, such as based on automated determinations that previously specified criteria are currently satisfied. The described techniques further include tracking information about changes that occur in one or more capacity utilization metrics of interest in response to dynamic modifications to the program execution capacity of the group, and then using such learned responses to determine a customized capacity modification policy that is configured for the actual operation of the software program(s) for the user. In some situations, the techniques are used in conjunction with a fee-based program execution service that executes multiple programs on behalf of multiple users of the service.
