SLA-aware broker for Public Cloud

Abstract

Cloud computing represents a disruptive innovation in the way of provisioning and managing IT and network resources. One of the main challenge of this paradigm is the monitoring of the actual services performance offered by different Cloud service providers. For this reason, service level management plays a central role to ensure the quality of services in Public Cloud and requires a structured approach to support the migration of critical services and sensitive data. This paper presents a conceptual SLA-aware broker, acting as a centralized control point between consumers and Cloud providers, to manage the end-to-end lifecycle of business services running on different Public Cloud environments. A case study implementation in a global telecommunication company demonstrates the feasibility and effectiveness of the proposed solution.
