EzWeb/FAST: reporting on a successful mashup-based solution for developing and deploying composite applications in the upcoming web of services

Service oriented architectures (SOAs) based on Web Services have attracted a great interest and IT investments during the last years, principally in the context of business-to-business integration within corporate intranets. However, they are nowadays evolving to break through enterprise boundaries, in a revolutionary attempt to make the approach pervasive, leading to what we call a user-centric SOA, i.e. a SOA conceived as a Web of Services made up of compositional resources that empowers end-users to ubiquitously exploit these resources by collaboratively remixing them. In this paper we explore the architectural basis, technologies, frameworks and tools considered necessary to face this novel vision of SOA. We also present the rationale behind EzWeb/FAST: an undergoing EU funded project whose first outcomes could serve as a preliminary proof of concept.

Service Scalability Over the Cloud

Cloud Computing promises an easy way to use and access to a large pool of virtualized resources (such as hardware, development platforms and/or services) that can be dynamically provisioned to adjust to a variable workload, allowing also for optimum resource utilization. This pool of resources is typically exploited by a pay-per-use model in which guarantees are offered by means of customized SLAs. Therefore, Cloud Computing automated provisioning mechanisms can help applications to scale up and down systems in the way that performance and economical sustainability are balanced. So, what does it mean to scale?

A user-centric approach for developing and deploying service front-ends in the future internet of services

Service-Oriented Architectures (SOAs) based on web services have attracted a great deal of interest and Internet Technology (IT) investment over the last few years, principally in the context of business-to-business integration within corporate intranets. However, they are now evolving and breaking through enterprise boundaries in a revolutionary attempt to make the approach pervasive. This is leading to what we call a user-centric SOA. A user-centric SOA is an SOA conceived as an internet of services made up of compositional resources empowering end users to collaboratively remix and ubiquitously exploit these resources. In this paper we explore the architectural basis, technologies, frameworks and tools considered necessary to tackle this novel vision of SOA. We also present the rationale behind EzWeb/FAST, an ongoing EU-funded project whose first outcomes could serve as a preliminary proof of concept.

Leveraging the Upcoming Internet of Services through an Open User-Service Front-End Framework

The Internet of the Future is expected to be composed of a mesh of interoperable Web Services accessed from all over the Web. This approach has not yet caught on since a global user-service interaction is still an open issue. This paper states our position with regard to the next generation front-end technology for the Internet of the Future. This approach will enable the massive deployment of services over the Internet in a user-centric fashion. This paper advocates the full development of front-end technologies to bring services closer to users, empowering them anytime and anywhere. It also outlines all the main gaps and technological challenges that have to be addressed. Finally, a model and an architecture are proposed for building these technologies into NESSIs Open Framework Reference Architecture, NEXOF-RA.

Delivering Mobile Enterprise Services on Morfeo’s MC Open Source Platform

This paper discusses the rationale behind Telef´onica’s strategic decision for Enterprise Mobility Solutions and presents MorfeoMC: an open source vertical componentbased platform for rapidly developing mobile applications and services that can be used to create comprehensive and integrated mobility solutions while concealing the complexity involved in managing multiple devices. The key architectural decisions in MorfeoMC are described, and the reasoning behind their selection is presented and compared with related work. For these purposes, the paper focuses on the MorfeoMC’s Rendering Layer, and describes how it allows for the development of applications and services according to a Channel Model supported by the principles of Service Oriented Architectures (SOA). It is stressed how this approach avoids the need for duplicating the services that implement the business logic when another access channel is added, thanks to its architecture of code generators. Finally, other key elements and techniques in MorfeoMC are also discussed.

SemanticWeb Content Adaptation and Services Delivery on Morfeo’s Semantic Mobility Channel

Content adaptation is crucial for universal Web access under varying conditions that may depend on device capabilities, network connectivity, user preferences, or user disabilities. Semantic annotations provide additional information about Web contents so that a content adaptation engine, based on Semantic Web technologies, can make better decisions on content repurposing. This paper presents MorfeoSMC: an open source advanced component-based platform that enables the development of semantics-aware mobile applications and services, and that solves the problem of how to make Web content usable on mobile devices. In particular, the paper focuses on how MorfeoSMC tackles the use of semantic markup in the information rendered for users through the mobility platform and in the Web content adaptation process. It also presents an innovative semantic matching framework for both services delivered in mobile environments and Web contents produced by these services. This framework is at the core of the semantics-aware Web content adaptation process.

Internet of Services

As the relentless march towards an Internet of Services (IoS) continues, it is of utmost importance for the telecoms industry to understand what the IoS is and upon what foundations and methodologies the IoS is based and built on. Further, how the telecom industry can leverage IoS research and push IoS capabilities on and beyond through innovation and how those services within the IoS should be designed and implemented need to be understood. Not only are these questions answered but also so as not to remain stationary in the world of IoS, the telecoms industry must comprehend the upcoming challenges and opportunities that the IoS will present. Within this chapter there are two perspectives taken on the more specific aspects of engineering services for the IoS. The first takes a first principles approach whereas the second takes one from the basis of an innovative methodology. This chapter will provide information and insights that seek to answer the former questions, starting with a discussion on what exactly a service is, moving through the innovation, design and implementation of IoS and its services, and finally arriving at a demonstrator of IoS that points towards its own future.

The Networked Forge: New Environments for Libre Software Development

Libre (free, open source) software forges (sites hosting the development infrastructure for a collection of projects) have been stable in architecture, services and concept since they become popular during the late 1990s. During this time several problems that cannot be solved without dramatic design changes have become evident. To overcome them, we propose a new concept, the “networked forge”, focused on addressing the core characteristics of libre software development and the needs of developers. The key of this proposal is to re-engineer forges as a net of distributed components which can be composed and configured according to the needs of users, using a combination of web 2.0, semantic web and mashup technologies. This approach is flexible enough to accommodate different development processes, while at the same time interoperates with current facilities.

Industrial Data Space Architecture Implementation Using FIWARE

We are in front of a new digital revolution that will transform the way we understand and use services and infrastructures. One of the key factors of this revolution is related to the evolution of the Internet of Things (IoT). Connected sensors will be installed in cities and homes affecting the daily life of people and providing them new ways of performing their daily activities. However, this revolution will also affect business and industry bringing the IoT to the production processes in what is called Industry 4.0. Sensor-enabled manufacturing equipment will allow real time communication, smart diagnosis and autonomous decision making. In this scope, the Industrial Data Spaces (IDS) Association has created a Reference Architecture model that aims to provide a common frame for designing and deploying Industry IoT infrastructures. In this paper, we present an implementation of such Reference Architecture based on FIWARE open source software components (Generic Enablers). We validate the proposed architecture by deploying and testing it in a real industry use case that tries to improve the maintenance and operation of milling machines. We conclude that the FIWARE-based IDS implementation fits the requirements of the IDS Reference Architecture providing open source software suitable to any Industry 4.0 environment.
