Proactive and Reactive Risk Management of IT Services of Cloud Environments
Abstract
Introduction: Most of emergencies in cloud environments are the results of ineffective risk management. For example, conflict situations lead to a service denial and require balanced and compromise solutions on resource allocation between the operating and systemic processes in the environment. Thus, the problem of risk management in cloud computing environments is extremely urgent. Purpose: We need to formalize the problem of effective risk management in cloud environments using the approaches with proactive or reactive control. Results: The conducted analysis of the main threats and vulnerabilities of cloud computing has identified the need of proactive or reactive risk management in order to form and implement the necessary countermeasures. The proposed information portrait of a risk allows you to visualize the aggregated assessment of the current state of a cloud computing environment, which is an indispensable condition for automated operational decision-making in real-time IT service management. A formalization has been given for a life cycle of a cloud environment supporting proactive or reactive control. This allows you to formulate the risk management problem in terms of dynamic programming. The essence of the proposed method is sequential multistage choice of one of alternative solutions, such as reducing the probability of adverse events, minimizing possible negative consequences of emergency situations, etc. The novelty of the proposed approach implies that it can be effectively used for either proactive or reactive risk management in cloud systems. Practical relevance: The obtained results can be used to visualize the operative situation within an integrated decision-support system aimed to manage IT services of cloud computing environments. The usage of the proposed information portrait of a risk will provide the necessary reactivity and interactivity of the interaction with the decision maker.Published
