Financial applications demand better performance and accuracy in a cloud than the traditional computing platforms. Therefore, designing financial software as a service (FSaaS) requires engineering and systematic approach. This paper has designed a financial SaaS component model and a service architecture supporting required flexibility, scalability, and allowing change in environment. This pape...

Software-as-a-Service (SaaS) is a software delivery model gaining popularity. Service Oriented Architecture (SOA) is widely used to construct SaaS applications due to the complementary characteristics in the two paradigms. Scalability has always been one of the major requirements in designing SaaS applications to meet the fluctuating demand. However, constructing SaaS applications using third-p...

Companies of all industrial sectors depend increasingly on their IT infrastructure and therefore demand more features, security and reliability regarding the provided IT services. Consequently, a user– and quality–oriented service management is desperately needed to fulfill the posed requirements. The previously developed MNM service model contributed to this research area by specifying a forma...

Service-oriented computing has emerged as the new area to address software as a service. This paper proposes a model for component based development for service-oriented systems and have created best practice guidelines on software component design.

V arious IT professionals have, at one time or another, erroneously used the terms software as a service (SaaS) and service-oriented architecture (SOA) interchangeably. At best, this faulty practice creates confusion; at its worst, it can lead to poor designs. Our goal, therefore, is to clarify the meaning of these two often used and abused terms. Briefly stated, the difference between SaaS and...

Software-as-a-service (SaaS) applications have experienced a decade of explosive growth, eliminating barriers in reaching users and enabling real-time interchanges intelligence. Using business analytics, SaaS are increasingly embedded the day-to-day activities businesses consumers with competition innovative pricing. Due to evolution cloud models, new issues surfacing challenge practitioners sc...

Despite its success in the software industry, Software-as-a-Service (SaaS) still struggles with fulfilling customer expectations regarding service quality. To contain customer churn rates to low levels, SaaS providers have to address their service quality weak spots and find out which factors are crucial for continued SaaS usage. Drawing on previous service quality literature, we develop a Zone...

In the context of the European Commission Project BEinGRID (FP6), the authors have defined a set of design patterns to develop software components based on service-oriented grid technologies. Some of these patterns have been used to improve the software components of a service-oriented grid middleware named GRid-based Application Service Provision (GRASP) that the authors have defined, designed...
