Abstract

With the enormous momentum that Cloud Services adoption has had over the past few years, it seems likely that many services which are critical to both enterprise and end users will be deployed in a Cloud context. The main driver for this migration is related to the economic advantages of Cloud based services compared to traditional models of hosting. However, as more critical services migrate to the Cloud, it becomes clear that the currently existing Quality of Service (QoS) guarantees being offered by Cloud providers are not sufficient. In this white paper we explore what the main QoS issues are today, their relation to the Quality of Experience (QoE) perceived by the users, how they can be improved, and what advantages exist for both providers and customers in the adoption of QoS / QoE monitoring and management technologies.
