- Dr. Kurt Vanmechelen of University of Antwerp, Belgium gave a seminar on “The Cloud Computing Paradigm: Technology, Markets, and Adaptation Factors” at TEMEP on October 1st, 2010.
Abstract of the talk: The cloud computing paradigm currently fuels one of the major technological and economical shifts in the IT industry. At its core, the paradigm introduces the notion of delivering IT hardware, development platforms and software as services over the internet. Contrary to numerous previous attempts to realize such a service-based model, procurement of these services is now possible with very limited coordination effort between consumers and providers. In addition, aspects such as its flexibility, scalability, cost-reducing potential, as well as the possibility for on-demand procurement of services, contribute to the paradigm’s uptake. This talk will introduce the concept of cloud computing and present the IT software and hardware infrastructure that currently forms the basis of its implementation. In addition, we outline the key factors that determine the suitability of cloud solutions for consumers and discuss the most important challenges and opportunities with respect to cloud adoption. Subsequently we highlight the market architecture that is currently in place for trading resources between consumers and Infrastructure as a Service cloud providers, and provide an outlook for future developments in this area. Finally, we motivate the need for the development of decision support systems in order to reduce the transaction costs for consumers in these markets.

- Dr. Ivona Brandic of Technical University of Vienna, Austria gave a seminar on “Fossi - Autonomic Resource Management in Clouds Considering Cloud-Based Resource Monitoring and Knowledge Management” at TEMEP on July 20th, 2010.
Abstract of the talk: Cloud computing represents a promising computing paradigm where computing resources have to be allocated to software for their execution. Self-manageable
Cloud infrastructures are required in order to achieve that level of flexibility at one hand, and to comply to users’ requirements specified by means of Service Level Agreements (SLAs) at the other. Such infrastructures should automatically respond to changing component, workload, and environmental conditions minimizing user interactions with the system and preventing violations of agreed SLAs. However, identification of sources responsible for the possible SLA violation and the decision about the reactive actions necessary to prevent SLA violation is far from trivial. First, in this paper we present a novel approach for mapping low-level resource metrics to SLA parameters necessary for the identification of failure sources. Second, we devise a layered Cloud architecture for the bottom-up propagation of failures to the layer, which can react to sensed SLA violation threats. Moreover, we present a communication model for the propagation of SLA violation threats to the appropriate layer of the Cloud infrastructure, which includes negotiators,brokers, and automatic service deployer.
- Prof. Dr. Ray Buyya of the University of Melbourne, Australia gave a seminar on “Cloud Computing: The Next Revolution in Information Technology” at TEMEP on May25th, 2010.
Abstract of the talk: Computing is being transformed to a model consisting of services that are commoditised and delivered in a manner similar to utilities such as water, electricity, gas, and telephony. In such a model, users access services based on their requirements without regard to where the services are hosted. Several computing paradigms have promised to deliver this utility computing vision and they include Grid computing, P2P computing, and more recently Cloud computing. The latter term denotes the infrastructure as a “Cloud” in which businesses and users are able to access applications from anywhere in the world on demand. Cloud computing delivers infrastructure, platform, and software (application) as services, which are made available as subscription-based services in a pay-as-you-go model to consumers. These services in industry are respectively referred to as Infrastructure as a Service (Iaas), Platform as a Service (PaaS), and Software as a Service (SaaS). To realize Cloud computing potential, vendors such as Amazon, Google, Microsoft, and IBM are starting to create and deploy Clouds in various locations around the world. In addition, companies with global operations require faster response time, and thus save time by distributing workload requests to multiple Clouds in various locations at the same time. This creates the need for establishing a computing atmosphere for dynamically interconnecting and provisioning Clouds from multiple domains within and across enterprises. There are many challenges involved in creating such Clouds and Cloud interconnections.
This keynote (1) presents the 21st century vision of computing and identifies various IT paradigms promising to deliver the vision of computing utilities; (2) defines the architecture for creating market-oriented Clouds and computing atmosphere by leveraging technologies such as VMs; (3) provides thoughts on market-based resource management strategies that encompass both customer-driven service management and computational risk management to sustain SLA-oriented resource allocation; (4) presents the work carried out as part of our new Cloud Computing initiative, called Cloudbus: (i) Aneka, a software system for providing PaaS within private or public Clouds and supporting market-oriented resource management, (ii) internetworking of Clouds for dynamic creation of federated computing environments for scaling of elastic applications, (iii) creation of 3rd party Cloud brokering services for content delivery network and e-Science applications and their deployment on capabilities of IaaS providers such as Amazon and Nirvanix along with Grid mashups, and (iv) CloudSim supporting modelling and simulation of Clouds for performance studies; and (5) concludes with the need for convergence of competing IT paradigms for delivering our 21st century vision along with pathways for future research.
- Dr. Peter Gloor of MIT, USA gave a seminar on “Collaborative Innovation Networks: Coolhunting through Swarmcreativity” at TEMEP on November 10th, 2009.
Abstract of the talk: Collaborative Innovation Networks, or COINs, are cyberteams of self-motivated people with a collective vision, enabled by technology to collaborate in innovating by sharing ideas, information, and work. Although COINs have been around for hundreds of years, they are especially relevant today because the concept has reached its tipping point thanks to the Internet. COINs are powered by swarm creativity, wherein people work together in a structure that enables a fluid creation and exchange of ideas. ‘Coolhunting’ – discovering, analyzing, and measuring trends and trendsetters – puts COINs to productive use. Patterns of collaborative innovation always follow the same path, from creator to COIN to collaborative learning network to collaborative interest network.
The talk also introduces Condor, a tool for dynamic semantic social network analysis. Condor applies a novel set of social network analysis based algorithms for mining the Web, blogs, and online forums to identify trends and find the people launching these new trends. The temporal calculation of betweenness of concepts permits to extract and predict long-term trends on the popularity of relevant concepts such as brands, movies, and politicians.

- Prof. Dr. Bernd Kraemer gave a seminar on “Engineering Service-based Applications with SCA” at TEMEP on October 27th, 2009.
The abstract of the talk has been: Computing with services has attracted much attention as a promising approach for developing distributed applications. The approach is often advertised as being superior to distributed component-based software engineering (CBSE), because it provides a higher potential to bridge heterogeneous IT application and infrastructure landscapes. It facilitates cross-institutional cooperation, lets services run over all kinds of ubiquitous communication infrastructure, 9 scales better and simplifies legacy software integration. If this were absolutely true, there would be no reason for a consortium of major vendors of service and Java EE technology to come up with a new specification, called service component architecture (SCA). This emerging standard tries to leverage service-oriented architecture (SOA) principles with component-based software development techniques. In this seminar we discuss some commonalities and fundamental differences of the CBS and SOA worlds. We illustrate SCA briefly using snippets of a simple application supporting conference management. Then we elaborate on the qualities and current deficits of SCA the light of CBSE findings and related works.
