Modelling Financial SaaS as Service Components

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 paper has proposed an integrated service-oriented architecture and a SaaS component model for financial domain that provides trequired scalability, flexibility and customisation. We have also demonstrated the design and customisation of service component interfaces to the financial simulation so that it provides automatic prediction models for investors to know accurate results in buy and sale prices. Therefore, large-scaled simulations can be achieved within a matter of seconds (13.5 seconds).
