If the volume of documents and the number of transactions increase because of the increased number of users over time, the additional volume can be handled by adding another server. In this case, you can balance the load between multiple servers. By introducing this system for one department initially and then expanding it along with the business expansion, you can continuously operate this system as a large-scale (terabyte-scale) system that will cross multiple departments in the future. In addition, this system employs a duplex-system method to perform fallback operation if a failure occurs, thus realizing a 24 x 7 production environment.
