Approaches to identify and develop Web services as instance of SOA architecture

Abstract

A b s w t -Web services underlying technologies andstandards allow interfacing, publishing, and binding services available on the Web and accessible through protocols based on the Internet. Moreover, Web services can easily live with distributed object computing middleware such as CORBA, DCOM and EJB, and integrated with semantic Web to overcome their Iimitations. These capabilities allow composition of business processes that cross the boundaries of an organization into new business solutions and ultimately e-business.Yet, Web services deployment is still hindered by technical and especially methodological issues. This paper concerns with approaches to develop Web services, namely their identification, design, deployment, and management The paper presents a comparative study of two perspectives of developing Web services: IT-oriented and business-oriented perspectives with respect to: (1) developing process, (2) used building blocks, (3) categories of Web services, and (4) wrapping of legacy applications. This comparative study aims at integrating both perspectives into a multiple abstraction level architecture with respect to a business model, where higher abstract levels deal with businessorientation, whereas the lower levels concern with IT.

Towards of service-oriented design architecture method

“…As software community has facing challenges in this area. A number of methods for SaaS from both academia and industry have been developed and compared [1], [2], [4], [7], [8]. This results in two main findings: F1.…”

Modelling business process with services: towards agile enterprises

“…In these BP modelling approaches, the focus is on specific perspectives, features, and capabilities or the process-data duality (Kumaran et al, 2008). Unfortunately, the dynamic nature of BPs is not stressed out in these approaches; neither have they considered adopting service-oriented architecture (SOA) principles when designing BPs (Al Rawahi and Baghdadi, 2005;Erl, 2009;Baghdadi, 2012). Recently, existing serviceoriented approaches are limited to the composition of BP with services (Cauvet and Guzelian, 2008), or extend existing BP modelling such as EPC notations to services (Stein, 2009).…”

On Standards for Application Level Interfaces in SDN

“…Alternatively, the Service Oriented Architecture (SOA) approach (where the REST is from) may offer personalized interfaces for the different resources [33]. The whole SOA model often compared with REST is based on the idea that different services have different interfaces.…”
