the service provider with an equivalent provider if for some reason the original provider is no longer able to offer the service. The basic reason for this ability is that with the service bus structure there is no need to hard-code the network address of the service end point into the client application. The bus provides for looking up the service end point address based on the content and context of the service request it receives from the client application. This routing capability is one of the three core capabilities an Enterprise Service Bus offers. In fact, this capability means that the service client is unaware of who the provider of the service is, and the service provider is unaware of the identity of the application making a service request. You ve learned that ORBs (or application servers) and asynchronous messaging provide some form of routing based on the content and context of the request. Therefore, both these technologies are in a position to form the backbone of the Enterprise Service Bus. Based on which of these two technologies is chosen as the backbone of an Enterprise Service Bus, there can be two types of buses. The first type of Enterprise Service Bus utilizes ORBs (or application servers) as the backbone. This type of Enterprise Service Bus has the advantage of being easy to set up and is comparatively less expensive. However, the functionality it provides does not scale as well where the rate of transactions is concerned. Therefore, this type of ESB should be used when lower volumes of transactions are expected. This type of ESB is usually designed to deal with Web Services, XML, and Java RMI only. The ESBs in this category also cannot handle a more diverse set of applications. The second type of ESB is based on the asynchronous messaging systems. It is relatively more expensive and requires a more elaborate setup. This type of Enterprise Service Bus has three main advantages over the first type. The first advantage is that this type of ESB provides a highly scalable solution in terms of the volume of transactions and therefore is able to support a much higher rate of transactions. The second benefit is that this type of ESB can be used to integrate a more diverse set of applications. Probably the most important advantage of this type of ESB is that it can guarantee delivery of the messages between applications. It is important to note that the Web Services themselves do not provide a guarantee of message delivery between applications This guarantee of message delivery may be required for certain transactions due to contractual or legal reasons. Also note that in the absence of this guarantee, the service consumer application may hang if the network connection breaks or if the service provider application is not running at the same time. The asynchronous messaging systems can ensure the delivery of messages by persisting them on both sides (the service consumer side and the service provider side) of the network.

Protocol Transformation In addition to providing a scalable solution to the problem of enterprise application integration, an Enterprise Service Bus pattern also provides solutions to the two remaining heterogeneity problems mentioned at the end of 7. The communication protocol mismatch problem arises because in a large enterprise different applications typically employ different protocols for communications. In other words, in the real world a proliferation of these protocols exists, including HTTP, HTTPS, JRMP, IIOP, and JMS. Because of this proliferation, sometimes a protocol mismatch will occur between the service consumer application and the service provider application. Therefore, without a facility to transform one communication protocol to another, the service consumer application will not be able to invoke the service offered by the service provider application. This inability to invoke the service is shown schematically in Figure 8.4. Ideally, the communication protocol should be standardized so that every application in the enterprise uses the same protocol. For example, an enterprise could standardize to using only HTTP, which is the standard protocol for Web Services. However, in the real world such a transformation may be difficult and impractical in most situations. The difficulty includes the lack of developer resources and time constraints. Also, the security and quality of service requirements might dictate the use of different protocols. Therefore, another core functionality that should be included in an ESB is a protocol transformation facility that can translate one protocol into another. With this transformation facility, the applications
