Abstract: The present disclosure relates to computer-implemented methods, software, and systems for on-demand outage notifications in a cloud environment. Data defining statuses of network calls exchanged between web agents registered at correspondingly different network segments of a cloud platform is evaluated to determine health statuses of the cloud platform. In response to receiving a request to subscribe an application for notifications for a current health status, registering, at the health service, the application to receive the notifications associated with health statuses of network connectivity of the cloud platform. The application is registered to receive the notifications at a subscription network address under a notification regime. A notification for the current health status of network connectivity of the cloud platform is dynamically provided by the health service. The notification is provided to the registered application according to notification rules defined in the notification regime.

Abstract: The present disclosure relates to computer-implemented methods, software, and systems for managing incompliances of application instances running in a cloud environment. Compliance requests can be generated for incompliant instances of cloud applications running on a cloud platform. In response, compliance checks for the one or more incompliant instances of cloud applications running on the cloud platform can be automatically executed. Incompliances can be identified by different compliance monitors instantiated at the cloud platform. Each compliance monitor is responsible for a particular type of incompliances. In response to identifying that a first instance of a first cloud application has a first type of incompliance, a maintenance action to be automatically executed by a first compliance maintainer running on the cloud platform is scheduled. The first compliance maintainer executes automatically a compliance measurement action for the first type of incompliance.

Abstract: The present disclosure relates to computer-implemented methods, software, and systems for database persistency. A first data request is received at a first instance of an application. The application is associated with multiple instances that share the database layer. In response to determining that the database is available for accessing after receiving the first request, the database is identified as a primary storage for the application, the data is written in the database and at an in-memory persistence storage of the first instance of the application.
