The lack of skilled programming personnel and the growing burden of maintaining customized software are forcing organizations to quit producing their own software. It's high time they turned to ready-made, standard components to fulfill their business requirements. Cloud services might be one way to achieve that goal.
One of the key interests in web services is the ability to compose them in order to build more powerful and complex ones running in an interoperable and distributed setting. Several languages, like BPEL, that describe such services have been proposed. Similarly to traditional complex systems, web service compositions may exhibit inappropriate behaviors in the presence of failures. Compensation mechanisms...
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, changes...
This paper presents a case for using standard services rather than developing one's own customized nuts and bolts software. It illustrates the size and complexity of object-oriented applications and defines what it costs to maintain them. The increasing maintenance burden is the main cause of the personnel shortage in many developed countries. The point is made that users cannot go on producing more...
In the current globalized world, characterized by strong Web based interactions, relationships between people and organizations are subject to fast changes. This situation justifies the need for an approach that can capture business changes and quickly implement them into computational systems. Considering that some business logic portions are quite volatile and susceptible to changes and other portions...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
We developed a quality of service (QoS) management system to support service level management (SLM) for global enterprise services. The QoS management system is integrated with one of our enterprise services in a preproduction system, an identical system as the production system but in a test environment. Lab experiments showed that our integrated solution helps global enterprise services to better...
