    Summary form only given. Cloud, SOA, Client-Server, mini computers, NoSQL, Hadoop ... the list can appear endless. What these various silver bullets have in common is that they promise to help solve business problems and that as IT solutions they often fail to deliver on initial promises. This talk takes a long-term perspective, examining first the original promise of these two complementary techn... View full abstract»

    To ensure that consumer requests for web services are served successfully and effectively amidst overwhelming options, one must narrow the web service search to only the most qualified, highest-ranked services. However, today, the ranking of services is done only with regards to static attributes or with a snapshot of current values, resulting in low quality search results. To improve user experie...

    When trying to understand a system that is based on the principles of Service-Oriented Architecture (SOA), it is typically not enough to understand the individual services in the architecture, but also the interactions between the services. In this paper, we present a technique based on dynamic analysis that can be used to obtain insight into how services work together to perform overall business ... View full abstract»

    The Quality of Service (QoS) in a distributed service-oriented application can be negatively affected by a variety of factors. Network volatility, hostile exploits, poor service management, all can prevent a service-oriented application from delivering its functionality to the user. This paper puts forward a novel approach to improving the reliability, security, and availability of service-oriente... View full abstract»

    Requirements from laws and regulations, as well as internal business objectives and policies, motivate enterprises to implement advanced monitoring tools. For example, a company may want a dynamic picture of its operational risk level, its performance, or the extent to which it achieves its business objectives. The widespread use of information and communication technology (ICT) supported business... View full abstract»

    End-users increasingly demand the provisioning of secure, scalable, reliable, flexible, resilient, and cost-efficient infrastructures, platforms, and software. However, the preservation of these properties, particularly in SOA and cloud environments, is extremely affected by distributed, heterogeneous, transient, and volatile context information. We envision the implementation of governance feedba... View full abstract»

    The fast evolution pace for cloud computing software is on a collision course with our growing reliance on cloud computing. On one hand, cloud software must have the agility to evolve rapidly, in order to remain competitive; on the other hand, more and more critical services become dependent on the cloud and demand high availability through firm Service Level Agreements (SLAs) for cloud infrastruc...

    By the 2010-2011 time period, many organizations had started the paradigm transition to using service-oriented architecture (SOA), but few had competed that transition. In that time period, most organizations were intermediate somewhere between started and completed. While they were in that intermediate status and beginning to get some of the benefits of SOA use, they continued to have to maintain... View full abstract»

    Inter-organization service-oriented compositions are governed by Service Level Agreements (SLAs). While the software is maintained and evolved in response to changing business requirements or technology, the governing SLA and software configuration designed to meet this SLA do not always change in step. SLAs are negotiated and may have legal standing, which makes their maintenance expensive and ti... View full abstract»

    The backbone of cloud computing platforms like Amazon S3 and Salesforce is formed by Ultra-Large-Scale (ULS) systems, i.e., complex, globally distributed infrastructure consisting of heterogeneous sets of software and hardware nodes. To ensure that a ULS system can scale to handle increasing service demand, it is important to understand the system's performance behaviour, for example to pro-active... View full abstract»
