Abstract: According to an example, to tune a cloud service, an event and an event type on a cloud server application are detected by monitoring at least one of a hardware value and a software value. An application parameter to tune is determined based on the event type, and a tuning priority of the application parameter based on historical tuning data is fetched. The application parameter is tuned by modifying a software variable. In the event that tuning the application parameter resolves the event type, the tuning priority of the parameter is increased. In the event that tuning the parameter fails to resolve the event type, the parameter priority is decreased, the tuning is rolled back, and a default tune setting is invoked.

Abstract: Examples relate to supporting interoperability in cloud environments. In some examples, an application topology is converted to a cloud product topology that supports a cloud product standard, where the application topology includes a general application and supports a cloud industry standard. Artifacts associated with the general application are imported into a product database, where the artifacts are exposed in the product database via a standard Internet protocol. At this stage, the cloud product topology is imported into the product database to obtain an imported topology, and the general application is deployed from the imported topology to a server computing device that supports the cloud product standard, where the general application accesses the artifacts via the standard Internet protocol after deployment.
