EU IST IRMOS Project Seminar - Real-time QoS Management in Clouds

Speaker(s): Michael Boniface
Organiser: Dr Stephen Phillips
Time: 10/12/2009 14:30-17:30
Location: B53/4025

Abstract

Cloud computing is one of the hottest buzzwords in IT today and is expected to provide the foundation infrastructure for the Future Internet. The commoditisation of IT resources and the ability to dynamically align user demand to resource provisioning has made Clouds the success we see today through offers by vendors such as Amazon, Microsoft Azure and Salesforce. However, significant research challenges exist that are barriers to adoption by the enterprise in the areas of security and quality of service guarantees

This seminar will present results from the EU IST IRMOS project which is addressing these barriers by investigating novel approaches to support real-time QoS guarantees for interactive real-time multimedia applications on service oriented infrastructures. It is an EC FP7 project with academic and industrial partners from across Europe including Xyratex (UK), University of Stuttgart (DE), ICCS NTUA (GR), Alcatel-Lucent (DE), SINTEF (NO), IT Innovation (UK), Scuola Superiore Sant'Anna (IT), Telefonica I+D (ES), Giunti Labs (IT), Deutsche Thomson OHG (DE), DFT Digital Film Technology (DE).

The seminar will cover our research on how to predict resource requirements for complex interactive applications and manage the quality of service through all layers of the cloud including software-as-a-service, platform-as-a-service and infrastructure-as-a-service (virtual machines, shared networks and high performance shared storage systems).

Agenda

14:30 – 14:45 Introduction- Real-time QoS Management in Clouds

Lecturer: Mike Boniface (IT Innovation)

Abstract: During this session, an introduction will be given, along with an overview of the IRMOS project. Cloud state of the art and background will be presented and the advances to be delivered by IRMOS will be analyzed, with a special focus on real-time aspects.

14:45 – 15:05 Mapping Rules Creation in SOIs

Lecturer: George Kousiouris (NTUA)

Abstract: The presentation will focus around methodologies and implementation of a service-oriented translation mechanism, connecting high level application terms to resource level attributes in the context of distributed, heterogeneous systems.

15:05 – 15:25 Modelling Interactive Real-time Applications on Service Oriented Infrastructures

Lecturer: Zlatko Zlatev (IT Innovation)

Abstract: In this session, techniques developed within IRMOS for modelling and predicting the resource and QoS requirements of interactive media applications hosted on third-party virtualised resources (storage, processing and networking) are presented. These models have value in many stages of the application lifecycle, for example when estimating resource needs in advance of execution, when negotiating QoS with service providers, when assessing the probable technical and economic outcomes of provisioning policies and management actions if either the application or resources do not perform as expected or need to be adjusted.

15:25 – 15:45 The Challenges of Data Storage for Soft Real-Time Applications in a Service Oriented Infrastructure

Lecturer: Dr. Darren Golbourn (Xyratex Corp.)

Abstract: This presentation will describe the issues and challenges facing anyone creating a data-centric time critical system, with particular emphasis on shared storage system performance in a service oriented architecture.

15:45 – 16:00 Coffee, tea and cakes

16:00 – 16:40 Virtualization of Network and Computational Resources

Lecturer: Dominik Lamp (University of Stuttgart)

Abstract: This session will focus on the IRMOS ISONI layer, a holistic approach to QoS–aware virtualization of networks and computational resources. Beyond the platform, an analysis on the current virtualization approaches and their issues in respect to specialized hardware will be given.

16:40 – 17:20 Admission Control and Scheduling for Meeting Real-Time Constraints

Lecturers: Prof. Tommaso Cucinotta and Fabio Checconi (SSSA)

Abstract: This session will include techniques for optimum allocation of virtualized over physical resources, while keeping probabilistic availability and response-time guarantees for the hosted applications. Furthermore, an advanced Linux-based real-time scheduler will be presented.

17:20-17:30 Q&A
