Embodiments for modeling and simulation of one or more architecture models for Big Data of an organization are described. In one example, at least one user requirement and set of model requirements are received from a user associated with the organization, where the set of model requirements is indicative of information relating to the one or more architecture models. Subsequently, one or more architecture models are generated for providing recommendation to the user, where the one or more architecture models are generated based on the at least one user requirement and the set of model requirements. Further, the one or more architecture models are simulated to ascertain performance of each of the one or more architecture models based at least on a pre-defined specification of architecture components associated with each of the one or more architecture models.
