Web Service Ecosystems Future Obstacles
written by gunther gerlach-2009
As seen through this section, web service ecosystems can generally be described as a logical collection of web services whose exposure and access are subject to constraints, which are characteristic of business service delivery. A lower level analogy can be found with application servers, where access and inter-operation of components is regulated by middleware functions such as discovery/brokering, remote access, object pooling, transactions, asynchronous messaging, persistence management, and so on.
