Abstract: Systems and methods for production readiness verification and monitoring are disclosed. A set of compliance requirements including one or more required-asset identifiers and a set of minimum deployment requirements for each required-asset identifier is received. Each of the one or more required-asset identifiers are associated with a cloud asset required for deployment of a target application. One or more probing messages are generated to determine an availability of each cloud asset associated with the one or more required-asset identifiers, at least one probing response is received from at least one cloud, and the cloud environment is identified as one of compliant or non-compliant for application deployment. The cloud environment is identified as compliant when each cloud asset meets each of minimum deployment requirements and non-compliant when a cloud asset fails to meet one of the minimum deployment requirements. The target application is deployed when the cloud environment is compliant.

Abstract: Updating a native class pointer in persisted compiled code for use in an execution environment other than the one in which the native class pointer was created. This is done by using an identifier, stored with the persisted compiled code, of the class first loaded by the class loader that also loaded the class to which the native class pointer refers. A table is maintained in the execution environment mapping class identifiers to class loaders, and the stored identifier is used to consult this table to find a candidate class loader from those in the current execution environment that can provide the correct updated pointer.

Abstract: Cognitive expected program code installation result assessment by a method that includes collecting environment information about a cloud computing environment and collecting description information about program code for potential installation. The method maintains a hierarchical model for determining whether the program code is expected to install properly on the computer system, and uses the hierarchical model for such determining, including performing an analysis that proceeds through level(s) of the model based on the description information and arrives at an indication as to whether the program code is expected to install properly. The method performs processing based on determining whether the program code is expected to install properly, for instance by generating and providing a recommendation to a user regarding installation of the program code.

Abstract: Provided are methods and systems for transition between a current cloud-based code environment and an updated cloud-based code environment. A method for transition between a current cloud-based code environment and an updated cloud-based code may commence with generating a steering policy.

The method may continue with receiving feedback concerning actual steering decisions made by the steering server. The method may further include automatically adjusting the steering policy in response to the feedback.

Abstract: Systems, methods and computer program products for providing a multi-tenant application execution environment that provides an object metadata service for managing application configuration in the multi-tenant environment. In one embodiment, a system has an application manager, a bundle manager, and a deployment manager. The application manager captures application metadata for a corresponding version of an application and defines a corresponding bundle which contains metadata that configures the version of the application. The bundle manager validates each bundle and stores the validated bundle in a bundle library in a data storage device. The deployment manager retrieves a master schema and one or more of the bundles from the bundle library and installs the retrieved master schema and the retrieved bundles, generating a tenant schema which is accessible by a corresponding tenant of the multi-tenant environment that has subscribed to the version of the application.
