Mechanisms are provided, in a cloud computing data processing system comprising a plurality of components, hosted on one or more hardware computing devices of the cloud computing data processing system, for transactional resource and topology management. A cloud service system is instantiated that comprises component instances having allocated resources. The cloud service system comprises orchestration engine logic which generates a transactional data structure that stores objects corresponding to transactions executed in association with resources and component instance state changes. The orchestration engine logic receives transactions associated with resources or component instances of the cloud service system and records the transactions as objects in the transactional data structure in response to receiving the transactions. In response to detecting an exception during operation of the cloud service system, a recovery engine utilizes the objects in the transactional data structure to restart or recover the cloud service system.

According to one aspect of the present disclosure, a method and technique for rate of operation progress reporting is disclosed. The method includes: responsive to completion by an application of one or more batch operations, storing an operation count corresponding to each completed batch operation; and, responsive to being polled by a monitoring module: identifying a time reporting window for the batch operations; and reporting a rate of progress meter value for the batch operations to the monitoring module based on the operation counts and the time reporting window.
