soa principles of service design by thomas erl pdf

, simplicity, HTTP protocol + text serialization is better suited for extranet applications. Of course, this is not absolute. In addition, the TCP protocol here is not limited to the remote invocation protocol must be located at the fourth layer of the OSI network model of the original TCP, which can contain any non-HTTP protocol above TCP. So, to answer the above question, webservices (classic wsdl+soap+http) is the technology that best conforms to the aforementioned

? How do I define a data type?use remote methods to invoke this pattern for WebService implementations, especially in the case of a simple request corresponding to the model. In this process, the XML file in the transfer describes more information about the remote method, such as the method name, method parameters , and so on.document exchange, compared to RPC in the XML file is not a remote method mapping, but a complete self-contained business document, when the

pattern for WebService implementations, especially in the simple request-appropriate model. In this process, the XML file in the transfer describes more information about the remote method, such as the method name, method parameters, and so on. document interchange, compared to RPC, is not a mapping of remote methods in an XML file, but a complete self-contained business document, which, when received by the service side, is preprocessed (such as

and reusable, which is important to quickly adapt to changes and reduce costs.Thirdly, in engineering, SOA focuses on service modeling and SOA-based design principles for architectural decision-making and design.Often meet customers ask the question:

IT environment is changes. Therefore, the work for service architecture designers will never end. For a designer who is used to building a house, it is necessary to turn to a new way of thinking to design a living organism. As written in the following article, the basis of SOA is similar architecture principles.

flexibility. However, it is a daunting task to have a new way of implementing the architecture in order to be strong and flexible. Enterprise architects must become "service-oriented architects", not only to understand SOA, but also to understand SOA practices. The distinction between architectural practices and the resulting architectural results is subtle and
