From the dark net to the cloudy data - Cloud network governance guidelines

Cloud computing services are accessible from anywhere and used worldwide. There is plenty of information about concepts, architecture and models to deploy cloud systems. On the other hand, there is a lack of standardized information about utilization, contracts, and main performance metrics demanded by cloud services. Those data are usually private, non-structured and even customers commonly do not know exactly their contract clauses and demands. In this paper, we conducted a survey to investigate how the actual demands of customers are, in order to provide useful information for the specification of new models and to support decision making in cloud businesses. Based on the results obtained, we have identified the strong dependency of cloud services in the network level, and systematized an approach for cloud network governance to advance the state-of-the-practice in cloud governance and its relationship with business process management.
