Cloud computing is currently gaining enormous momentum due to a number of promised benefits: ease of use in terms of deployment, administration, and maintenance, along with high scalability and flexibility to create new services. However, as more personal and business applications migrate to the cloud, service quality will become an important differentiator between providers. In particular, quality of experience as perceived by users has the potential to become the guiding paradigm for managing…

Quality of Experience in Cloud services: Survey and measurements

Measuring of QoE for Cloud Applications

TLDR
According to NIST, cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Cloud Applications Management - Issues and Developments

TLDR
There is insufficient discussion in the area of trust management and security as it relates to cloud applications management and this would be beneficial to prospective cloud users, researchers and cloud service providers alike.

Survey of Elasticity Management Solutions in Cloud Computing

TLDR
This chapter provides an overview of the concept of cloud elasticity and proposes a classification of the mechanisms and techniques employed to manage elasticity, using this classification as a common ground to study and compare elasticity management solutions.

Quality-driven optimal SLA selection for enterprise cloud communications

TLDR
A multi-objective optimization framework making use of application-specific QoE estimation tools to tackle with the conflicting objectives of price and quality and demonstrate its application to a cloud-based teleconferencing service as a case study is proposed.

On QoE-Oriented Cloud Service Orchestration for Application Providers

TLDR
Evaluation of QoE-oriented algorithms using realistic numerical simulations, real-world cloud testbed experiments with actual users and ASP case studies show notably improved performance over existing cloud service orchestration solutions.

Use- and QoE-related aspects of personal cloud applications: An exploratory survey

TLDR
An online survey among users of personal cloud services and applications is conducted in order to gain a better understanding of how and why they are used and to detect possible QoE influencing factors and relevant features.

Flexible Framework for Elasticity in Cloud Computing

TLDR
This thesis investigated all the aspects of elasticity to manage efficiently the resources provisioning and de-provisioning in cloud computing and solved such challenges as how to overcome the problem of over- Provisioning and under-Provisioning.

Application of Quality of Experience in Networked Services: Review, Trend & Perspectives

Cloud Computing: An Overview

TLDR
This overview presents some of the key topics discussed during the ACM Cloud Computing and Virtualization CTO Roundtables of 2008 and summarizes the fundamental issues generally agreed upon by the panels and should help readers to assess the applicability of cloud computing to their application areas.

A Novel Architecture for Multimedia Distribution Based on Content-Aware Networking

  • E. BorcociD. NégruC. Timmerer

    2010 Third International Conference on Communication Theory, Reliability, and Quality of Service
  • 2010
TLDR
A novel virtual Content-Aware Network (CAN) layer is proposed as a part of a full layered architecture, focused, but not limited to, on multimedia distribution with Quality of Services (QoS) assurance.

Optimal resource allocation for multimedia cloud based on queuing model

TLDR
This paper optimize resource allocation for multimedia cloud based on queuing model and demonstrates that the proposed optimal allocation scheme can optimally utilize the cloud resources to achieve a minimal mean response time or a minimal resource cost.

An Economic Traffic Management Approach to Enable the TripleWin for Users, ISPs, and Overlay Providers

TLDR
It is shown that different ETM approaches have to be combined for an overall solution and a suitable architecture enabling the implementation of a TripleWin solution is provided.

Improving the QoE of Citrix Thin Client Users

During the last years so-called ``Thin Client'' architectures have become very popular. Thin Clients are simple end user devices, which are provided with content and services by powerful servers.

Multimedia Cloud Computing

TLDR
A multimedia-aware cloud is presented, which addresses how a cloud can perform distributed multimedia processing and storage and provide quality of service (QoS) provisioning for multimedia services, and a media-edge cloud (MEC) architecture is proposed, in which storage, central processing unit (CPU), and graphics processing units (GPU) clusters are presented at the edge.

A generic quantitative relationship between quality of experience and quality of service

TLDR
The IQX hypothesis is a strong candidate to be taken into account when deriving relationships between QoE and QoS parameters and is shown to outperform previously published logarithmic functions.
