Legacy to Service-Oriented Architecture migration approaches have been extensively researched over the last decade, primarily to reuse the valuable business logic that resides within legacy applications. Interestingly, most of the proposed approaches fail to cover the complete process from the technological, organizational and business perspectives. This paper presents a structured six-phase proce...

Automation of workflows has been the focus of much research for more than three decades. There has also been significant research about the evolution of workflows. In this paper we describe how to achieve automation of workflows, not only in a single application but in an entire landscape of applications. How can distinctive types of workflow applications be built in an IT landscape? How can the S... View full abstract»

Large legacy applications are rapidly becoming less practical for both the organizations they service, and for the organizations responsible for servicing them. This paper establishes a process model for refining the initial concept associated with overhauling legacy enterprise software applications, and examines a case study of that process as applied to a real-world legacy software system to dem...

This paper describes the reuse of existing classes and methods in an existing object-oriented system as web services in a service-oriented architecture. The approach presented here identifies the interfaces and public methods which can be invoked from outside and generates a WSDL interface to access them. It is a bottom-up approach to creating web services which allows business processes to reuse ... View full abstract»

Web services not only are one of the most promising technologies in terms of the availability of network services but also solve the problem of integrating heterogeneous applications on the web. Because of their increasing popularity, maintainability has become an important issue as it helps to reduce maintenance costs and improve software quality. However, from the perspective of evolution and ma... View full abstract»

In this paper, we present a tool supported approach to perform efficient regression testing of web services. Functional and non-functional web service testing is done with the help of WSDL parsing and regression testing is performed by identifying the changes made thereafter. We identify, categorize, and capture the web service regression testing needs into three different categories, namely, chan... View full abstract»

A main incentive in favor of migrating to the cloud is delegating the management of large volumes of data to cloud providers. To make the notion of data cloud successful, providers must ensure availability, reliability, and data integrity among other qualities. Few researches so far have addressed the potential benefits data cloud provisioning can offer for energy efficiency. In this case study ca... View full abstract»

Many software companies have in mind jumping into the Cloud in order to take advantage of this technical paradigm as well as the innovative business models associated (such as SaaS). However, taking this leap becomes a hard task since it implies a high uncertainty and a raised risk without knowing when or even if the investment will be recovered. This paper presents the solution proposed by the AR... View full abstract»

Autonomic computing seeks to render computing systems as self-managed. In other words, its objective is to enable computer systems to manage themselves so as to minimise the need for human input [5,6]. Software architectures can be used in order to express constraints to be maintained all along the execution of a system and, conversely, to present the state of the running system. In this paper, we... View full abstract»

In the cloud computing technology stack, infrastructure has matured more than platform or software service technologies with respect to languages and techniques used for architecting and managing respective applications. Platform-as-a-Service (PaaS) emerges as a focus for the near future that we will focus on. We look at software architecture and programming concerns in the context of migration to...

The deployment and the execution of applications on dynamic Cloud infrastructures introduces new requirements of adaptability with respect to monitoring. Specifically, the governance of service choreographies enacted over Cloud-based solutions relies on the observation and analysis of events happening at different abstraction layers. Adaptability requirements are even more evident when monitoring ... View full abstract»
