Web services engineering: promises and challenges

Software Methodologies for the Engineering of Service-Oriented Industrial Automation: The Continuum Project

“…So, integration and collaborations are key issues. And, dynamic provision and evolution of services are a new area of Software Engineering [9], that change the way that software is developed and deployed.…”

Dynamic Availability Estimation for Service Selection Based on Status Identification

“…To estimate web services availability for service selection, many previous approaches have been proposed. Zeng et al [23,24] propose to estimate availability as Equation (1). Ava is the calculated value of availability and Tup is the total amount of time in which the services is available during the last T seconds.…”

“…In Equation (8), Tup denotes the uptime of the monitoring device [17], which is much different from the "last T " seconds in Equation (1). The time periods Tup and T down are measured by independent interaction with frequency one minute [18], which means, if the client program successfully accesses the services once in one minute (a single time point), then this minute (a time period) is regarded as "up".…”

“…In particular, many researchers regard service-oriented methodologies as a promising solution for future distributed applications [1,16,21]. Meanwhile, because of the distributed and dynamic nature of web services, many researchers propose that quality of services (QoS) should be a key factor for the success of building critical service-oriented applications [16,4,20,8,14,7].…”

Model driven benchmark generation for web services

“…However, many challenges remain, especially ensuring that Web services solution can meet specified performance requirements [2].…”
