Various embodiments of the present disclosure are directed to improved systems, apparatuses, methods, and computer program products for managing and synchronizing independent computing resources. In this regard, embodiments may manage and/or synchronize computing resources, data, and the like between the embodiments and various independent third-party systems, while handling transmission errors that occur during synchronization. In an example context, embodiments manage synchronization of subscriber profiles between the various systems. Some embodiments manage computing resources for processing one or more unprocessed actions of various types, for example by scaling executed process instances based on an action queue length and a queue length minimum threshold and/or queue length maximum threshold.
