Staged rollout framework for feature release

Abstract:

An application update system performs staged rollouts to push new versions or features of applications to users quickly and with minimal negative impact to the users. The application update system allocates users of an application to populations. The populations specify a subset of users to receive a feature update for the application. The application update system performs a staged rollout of the feature update by iteratively pushing the feature update to the identified subset of users, monitoring the performance of the feature update, and, based on the performance, the application update system reallocates users to populations. For example, when the feature update performs successfully, the application update system allocates additional users to receive the feature update. When all users of the application have received the feature update, the staged rollout is designated as complete.
