Abstract

The strong adoption rate for Cloud-based applications has so far been mostly based on the perceived economic advantages. Cloud-based services are often cheaper to deploy and host and they offer greater technical advantages, for example with respect to scalability. The migration of more critical services to the Cloud, however, will not only depend on the economic aspects, but will also be predicated on the Cloud-based solutions being reliable and performing as well as the legacy ones. In this context, understanding the factors affecting the Quality of Service (QoS) and Quality of Experience (QoE) for Cloud-based services will be critical in order for customers to choose the right Cloud offerings and for service providers to differentiate themselves.
