(FSaaS) requirerss engineering and systematic approach. This paper has demonstrated
a systematic approach to developing large scaled financial applications with current
technology such as SOA which supports SaaS features to be integrated with cloud
solutions. This paper has also demonstrated the design and customisation of service
component interfaces to the financial simulation so that it provides automatic predic-
tion models for investors to know accurate results in buy and sale prices. Therefore,
large-scaled simulations can be achieved within a matter of seconds (13.15 seconds).
