Abstract: Host systems for resuming operation of a virtual compute instance may be identified that support features enabled for the virtual compute instance. Virtual compute instance features may be enabled at runtime prior to a virtual compute instance being stopped. When a virtual compute instance is started again, these features may be used to identify a host system that supports at least these features so that when the virtual compute instance resumes operation on the identified host, the features can be enabled.

Abstract: Methods, systems, apparatuses, and computer program products are described herein for the development of applications and/or workflows that are enabled to transmit and/or push notifications to end-users. The developer (or “maker” or “creator”) of the application(s) and/or workflow(s) are enabled to develop such application(s) and/or workflow(s) without having to be expert programmers (i.e., such a developer may be a business user with little to no programming experience). The techniques described herein enable the transmission of cross-application push notifications to end-users of a target application in a secure manner. For example, push notification requests may be monitored to determine whether they are authorized to be transmitted in accordance with an administrator-configurable policy rule, thereby preventing unwanted push notifications from being transmitted. Moreover, computing resources may be scaled up (or scaled down) depending on how many users are to receive a particular push notification.
