In this paper, the authors introduce the Risk Visualization-as-a-Service (RVaaS) and present the motivation, rationale, methodology, cloud APIs used, operations and examples of using RVaaS. Risks can be calculated within seconds and presented in the form of visualization to ensure that unexploited areas are exposed. RVaaS operates in two phases. The first phase includes the risk modeling in Black Scholes Model (BSM), creating 3D visualization and analysis. The second phase consists of calculating key derivatives such as delta and theta for financial modeling.
