The architectures of currently sold Enterprise Systems were developed in a time when the amount of data to be processed was limited. Since then the necessity to capture and process real-time data from multiple sources has surged and needs to be considered in a world where everything must be exchanged and available anywhere, anytime and in any format. Yet the abstinence of novel approaches on the architectures of Enterprise Systems creates a gap between the increasing requirements and existing information systems. In this paper, we suggest a new architectural design approach, which will close the gap between increasing requirements and existing information systems. In order to determine a future-proof architecture, the authors conducted a Delphi survey where technology providers and users were inquired on the business needs and technical requirements. The result of the Delphi survey has been used to create a proposal for a different approach towards ES architectures
