Service quality assurance in multi-clouds

Abstract

A particular problem of cloud environments is the assurance of a certain level of service quality. The problem is escalated in the case of building support platforms for using multiple clouds. Various partial solutions to ensure a certain quality level of the cloud services have been investigated in the last half decade. This paper analyzes the existing approaches to define, model, evaluate, estimate, measure of optimize the quality of services offered to cloud-based applications. A particular approach is detailed, the one that uses model-driven engineering techniques. Moreover, the special case of designing data-intensive applications, the appropriate quality of service attributes are identified.
