Enterprise Service Bus (ESB) software products centralize integrations with a bus or hub-and-spoke topology. They help to reduce the degree of required system coupling within an application landscape. However,these solutions are regularly associated with high costs and a proprietary single point of failure.
ESBs fall short as a core component of future-oriented system integrations.
As a result, ESBs in many scenarios no longer meet current or future integration requirements. They impose a central infrastructure and team that implement all integrations with (often) proprietary solutions. Flexibility for the development of new business models is low. What is needed here is cooperation between systems from different companies such as FinTechs, Insurers, Banks, Sales organizations, comparison portals, customer and market platforms. Only through flexible and open integration architectures - without vendor lock-ins - is effective cooperation realistic here, even at the technical level.
