This article is describing, that interet is rising of new services and applications.
The internet architectures are described to avoid rigidity of layered structures by TCP/IP stack.
Its context introduces a framework for cost and prise that enables requesters and providers to interact and create new business models for the Future Internet.
It mentions the Quality of service (QoS) or energy effiency were introduced as critical issues and should be considered and integrated into the architecture from the start.
And so it baiscally produces Furture Internet (FI) architectures based on Service-orientated architecture.
And one of the main aspects is proposals to define effiecient, flexible and scalable process for service.

There about several sections to this paper:
section 2 shows challenges for providing
services in Future Internet. Section 3 gives an overview of Future Internet
initiatives, service composition and socioeconomic aspects.
Section 4 provides the Service Oriented Architecture considered in
this approacg proposal.
Section 5 presents the costing framework to be applied with service-oriented architectures for Future Internet.
6 & 7 propose service discovery and service composition processes.

It frameworks defines Composed Service (CSs) as a Workflow (WF) of funtionalities or Atomic Services (ASs) and Atomic Mechanisms (AMs)
It finds that the price of all services depends on the set of of assumptions made by providers in order to obtain a balance between cost and benifit.
This is where the business model (BM) that takes into account  series of components like price, convenience, commodity-plus, experience, organisation planning, distribution channels, intermediaries, trust chains and innovation.

Based on services composition mechanics and granularity, this costing framework is divided into three main components:
-Atomic Costs
-Node Cost
-Composed Service Cost
This is a very good quantitative article showing an SOA in Internet. I’m still trying to graps its complex techniques.
Its SOA paradigm seems to show that its flexible and scable with its approach for creating clean-state acrhitectures for future Internet.
Its framework shows that it combines to the requesters need  and also how services are changed accroding to different pricing models.

Assessing the Business Benefits of Service Oriented Architecture: A Case Study in The Banking Sector

Evangelia Angelopoulou has written an article that she hopes will give a clearer understanding of the benefits of service oriented architecture through a case study in the banking sector. In the paper they present a SOA definition and a literature review on domains related to IT business value and Information Systems evaluation. They then propose a framework of SOA business benefits derived from academic and industrial publications as well as our professional experience. The framework is validated through a case study in a large corporation of the Greek banking sector.

The case study as part of this paper was performed in a large financial organization. The main purpose of this case study was to create an organization‐wide service repository exposed to all systems/applications, providing information from a single point of access and secondly to provide an abstract, easily monitored and maintainable solution to the integration problem of the bank instead of point‐to‐point interfaces by encapsulating all heterogeneity of bank’s systems behind a middle‐layer.

In her conclusion, Evangelia talks about how in both academia and industry, there are still a lot of research gaps especially in the business domain of SOAs. She described the company, the project objectives, challenges and implementation approach and then presented the business benefits derived from the project. Overall average of ratings validates that SOA produced significant business benefits in the case of large financial organization.
