An innovative cyber culture and computing of social governance of citizens is proposed, aimed at the moral metric cloud service of social groups through the leverage of digital monitoring and expert evaluation of social processes and phenomena. Cyber culture is defined as the development level of social, technological, moral and material relations between society, the physical world and cyberspace...
The notion of a BPaaS is currently taking a momentum as many organisations attempt to move and offer their business processes (BPs) in the cloud. Such BPs need to be adaptively provisioned so as to sustain the service level promised in the respective SLA. However, current cloud-based adaptation frameworks cannot cover all possible abstraction levels and usually rely on simplistic adaptation rules...
The fast expansion of Internet-based multimedia services like Netflix, Skype or YouTube -- the so-called Over-The-Top Services (OTT) -- have increased the quality requirements of these services from the point of view of the user. In this sense, it is important not only to ensure a good Quality of Service (QoS) level -- technical metrics -- but also a high level of Quality of Experience (QoE) -- subjective,...
Today's social-coding tools foreshadow a transformation of the software industry, as it relies increasingly on open libraries, frameworks, and code fragments. Our vision calls for new intelligently transparent services that support rapid development of innovative products while helping developers manage risk and issuing them early warnings of looming failures. Intelligent transparency is enabled by...
This paper focuses on batch environment of an enterprise. We use various data sources such as dependency data, alert and ticket data, and run history data of the jobs in batch systems to build a model of batch operations. We enrich the model with various attributes derived by graph analysis of dependency data, time-series analysis of execution history of jobs, and text and statistical analysis of...
As business processes continue to gain relevance in different domains, dynamicity is becoming a great concern. Static processes no longer cover the actual needs of constantly changing environments, and process adaptation is a must in order to maintain competitive levels. While creating dynamically adaptable business processes can be a challenging task, undoing these adaptations is a natural functionality...
Advanced case management gives enterprises the flexibility to organize their business operations in an efficient and transparent manner while providing knowledge workers the opportunity to proceed towards their goals and to react to exceptions as required in each individual situation. Powerful analytics based on pervasive observation of end-to-end case executions help to detect exceptional situations,...
Computing resource provisioning through the use of the Cloud computing paradigm has triggered revolutions in modern day computing. It is a new paradigm for deploying services on rented machines. On the other hand, Service Oriented Architecture (SOA) has gained wide adoption among organizations due to the importance of collaborations and outsourcing. Therefore the Cloud's enormous capacity with comparable...
Data as a Service (DaaS) emerges as a new trend for exchanging data between independent data owners and data users so that data can be acquired on demand through standard protocols across heterogeneous platforms. It is usually a user-interactive and iterative process to compose the services into various data-driven business scenarios of data acquisition, analysis, and other processing activities....
Service-oriented architecture is a paradigm for modeling and enacting business processes that promotes improved flexibility and monitor ability through the composition of loosely-coupled Web services. However, such process-centric composition, with focus on invoking Web services to reach a stated goal, still does not provide the desired flexibility. Web services implementations are typically locked...
The paper concentrates on analyzing and discussing data pooling structure, online data pooling partition storage model, structure model of enterprise cloud storage system, proposes the design plans of data control and cloud storage. Storage management control optimized is an effective method that will reduce the working time to large-scale data storage management. Combining storage devices and control...
Traditionally disparate approaches have been used for business process modeling and business process monitoring. The connections are often achieved through IT-level models e.g. state machine models. In this paper we provide a unified model - managed business artifacts - that captures the process modeling and monitoring concerns. We establish the connections through a business-level model. The concepts...
The execution of composite web services with WS-BPEL relies on externally autonomous Web services. This implies the need to constantly monitor the running behavior of the involved parties. Moreover, monitoring the execution of such processes is critical to enforce business policies and meet reliability goals. This paper proposes a stateful aspect extension to WS-BPEL, as a solution to support flexible...
To catch up with today's fast changing business markets, web services has never slowed down its paces for evolution. As a consequence, service consumers have to employ in-time upgrades to guarantee continuous business integrity and avoid unnecessary runtime errors in their IT systems. However, a new web service release can involve hundreds of changes, and thus it is non-trivial for the service consumer...
This paper advocates the need for a mechanism that will allow the evaluation of the provided quality of service (QoS) by a service provider to a service customer in B2B service provisioning. Furthermore, this study goes on with presenting the feasibility of this mechanism by designing and testing a reference implementation that can be used in a service oriented architecture (SOA) environment which...
Detecting complex patterns in event streams, i.e., complex event processing (CEP), has become increasingly important for modern enterprises to react quickly to critical situations. In many practical cases business events are generated based on pre-defined business logics. Hence constraints, such as occurrence and order constraints, often hold among events. Reasoning using these known constraints enables...
A generic test process should support all approaches "formal to informal" and mixed approaches within, and across, all test levels. But widely-accepted formal approaches, from current standards, certification syllabi and tools, have explicitly-defined test cases as the key underlying entity: not all real-life approaches use explicit test cases. Also, testing is maturing beyond merely "finding...
An important issue to the adoption of any enterprise architectural approach is the availability of tools to support the development, storage, presentation, analysis, improvement and evolution of enterprise architecture representations. As with enterprise architecture methodologies, enterprise architecture tools to support the architectural development process are still emerging. Most important software...
