Message buses without smarts

In contrast we have seen considerable success with Simple Message Buses where the integration problems are solved at the end points, rather than inside a vendor ESB system. The most well known Simple Message Bus approach is one based on the principles of REST and leveraging the proven scalability of the web. However organizations that have already invested in ESB infrastructure can leverage the useful parts of that infrastructure (reliable messaging etc) while still using a Simple Message Bus approach and performing integrations at the edges of the system.
