2 Need for middleware frameworks

As operating systems manage the collaboration of tasks on a given computer, a set of applications distributed over interconnected machines needs equivalent services but with coherency guarantees : this is the role of middleware. Furthermore, the actual trend is to put most of the middleware services on standalone machines. For instance, the discovery services and the event services proposed by the OSGI framework can efficiently be used on standalone computers. So many actual component-based approaches for the conception of operating systems are proposing middleware services as main foundations.

The common method for building any software application is decompose into components that application (distributed or not). The components export interfaces ” the only way to use them (interfaces for controlling, emitting or receiving data, configuring, testing, securing, billing, debugging, etc). The distribution should be considered as a process for optimizing hardware resources, so the implementations should be automatically generated.
