We analyze the issues related to the management of sessions in Web Applications running on Auto Scaling IaaS systems. We focus on the effect of scaling operations (i.e., dynamic addition/removal of virtual machines) on the Sticky Session paradigm provided by Web Servers. We propose two different solutions, namely Session Monitoring and Session Migration, and describe the implementation of the former in the Open Source Eucalyptus IaaS system.

As the number of available web services published in registries and on web sites increases, web service discovery becomes a challenging task. One solution to the problem is to use distributed web service search system composed of domain specific sub service discoverers. Using ontology is the most common practice to specify domain knowledge. However, an important problem at this point is the lack of semantic annotation for currently available web services. For this reason, there is a strong need for a mechanism for semantic annotation of unannotated services. In this work, we propose a web service semantic annotation method that uses lexicon-based alignment. Lexicon-based alignment considers the different senses of the words, and hence it can find the association between the service and the ontology more accurately than previous alignment techniques.

Service Oriented Architectures (SOA) can be used for the design and creation of reusable business services that may be shared across the company. The complexity of the business processes, and their changing environment sheds a highly complex SOA architecture solution as a result. Without an adequate control measure SOA could quickly lead to be unmanageable for IT administrators and architects. In this paper we propose a strategy based on Model-Driven Engineering (MDE) to provide support to architecture governance, allowing the definition of policies on SOA systems as well as the assessment of these policies within the solution architecture.

This paper presents Virtual Rank, a load balancing technique which is on the basis of virtual machine migration. Virtual Rank proposes a solution that determines when to migrate virtual machines, and where to migrate. Most of the traditional load balancing techniques are based on threshold, whereas Virtual Rank predicts load tendency in the upcoming time slots. It ensures a small transient spike which does not trigger needless virtual machine(VM) migration. After triggering migration, the technique selects the potential migration target applying the Markov stochastic process. Finally the weighted probability method is applied to confirm the final migration target. It resolves the accumulation conflicts, as well as increases the stability. We implement our techniques in virtual computing environment iVic and conduct a detailed evaluation using a mix of CPU, network applications. We demonstrate that in different scale virtual network, Virtual Rank achieves better load balancing performance, compared with traditional methods.

The size and complexity of medical record databases makes extracting information challenging. With the tables numbering in thousands, even database analysts have trouble finding important fields and discovering various associations between tables. This paper presents a case study of our initial method of finding minimum Steiner trees in the Epic Clarity Reporting database to solve this problem. In addition, we present a web service architecture that can be used to extend our approach to multiple databases.

As scientific workflows are becoming more complex and apply compute-intensive methods to increasingly large data volumes, access to HPC resources is becoming mandatory. We describe the development of a novel plug in for the Tavern a workflow system, which provides transparent and secure access to HPC/grid resources via the UNICORE grid middleware, while maintaining the ease of use that has been the main reason for the success of scientific workflow systems. A use case from the bioinformatics domain demonstrates the potential of the UNICORE plug in for Tavern a by creating a scientific workflow that executes the central parts in parallel on a cluster resource.

Cloud computing has been attracting much attention since its birth. How to cloudify software systems especially legacy applications in the cloud era is becoming increasingly important. Based on RGPS meta-model framework and International standards-ISO/IEC 19763, an architecture for cloudification of legacy applications is proposed, which consists of three parts: a Web portal, a SaaS service supermarket, and a SaaS application development platform. In this paper, we take an open source software as an example to illustrate the proposed approach. Based on the architecture and supporting techniques on software virtualization and multi-tenancy, we develop a prototype Cloud CRM to demonstrate the basic procedure for cloudification of legacy applications, as well as the feasibility of the proposed approach.

Service-oriented architecture implemented by Web Services is one of the most popular and promising software development paradigm that has brought some challenging research issues today. One of the most important issues is how to automate web service composition at design phase. Currently, there are many researchers concentrating on service composition problem that can be partitioned into three parts, dynamic workflow composition, QoS-aware, and transaction-aware service selection. This paper addresses the issue of automatic composing Web Services into an executable workflow not only according to user¡¦s functional requirements but also to their transactional properties and QoS characteristics. We propose an automatic composition approach through genetic algorithm to satisfy user¡¦s functional requirements, QoS criteria, and transactional requirements automatically at the same time. Experimental results are presented.

Given the projected growth in IT over the coming decades it is important that the supply of, and demand for, computing services be made as environmentally friendly as possible. One of the key technologies for achieving this will undoubtedly be cloud computing which opens up many new opportunities for streamlining the way computing services are delivered and used. Several research projects have therefore recently started to examine ways of improving the efficiency of cloud computing infrastructures and of understanding the energy efficiency of computing algorithms. However, to date these have mainly focused on increasing the efficiency of cloud computing services at the relatively low "platform" and "infrastructure" levels of abstraction at which they are typically offered today. In this paper we argue that to maximize the environmental benefits of cloud computing, both from the demand as well as the supply point of view, it is necessary to raise the level of abstraction at which cloud services are delivered and consumed. To this end, we introduce the vision of "Modelling as a Service (MaaS)" and explain how it provides an essential foundation for reducing the environmental impact of computing services.
