Title: Client-side evaluation of Quality of Service in Cloud Applications
Subject: Computer Science
Level: Basic
Description: CONTEXT AND AIM:
Cloud-based technologies have been extensively to improve the time- and cost-efficiency, the scalability, and maintainability of internet-based services. The specification of the Quality of Service (QoS) level is typically described through the definition of Service Level Agreements (SLAs), included in the service provider contract. Currently, most of the QoS techniques utilise service measurements that are collected by the network elements, adopting a service-side QoS monitoring, while a client-side perspective may be more relevant for the customers’ perspective.
The client-side QoS approach gives the major role to the clients to evaluate the dedicated services through gathering the network measurements and reporting the necessary information.


GOALS:
The scope of this thesis is to empirically evaluate the performance of cloud-based services from a client perspective, verifying the ability of using client-based QoS measurements to detect service degradation, and the possibility to counteract to such degradation through the allocation of more resources. The study will rigorously follow empirical studies guidelines. In particular the work will:

- collect relevant publications about the current state-of-the-art;
- identify workloads, scenarios and metrics for the evaluation;
- evaluate currently adopted SLAs in industrial environments;
- perform experimental evaluation of the measured performance from the client side.


THESIS EXECUTION:
The work described in this thesis proposal is expected to be developed by one student. The work will be done within the project Future factories in the Cloud (FiC) (http://www.es.mdh.se/projects/430-FiC), in which companies like Volvo and e-on are part of the steering committee, providing interesting industrial use cases.
