when using peer-to-peer technology. It's a nightmare to be forced to deal with incompatible versions of multiple peer networks.
The N-tier and/or combination of these methods (Figure 15) should be used only for very complex systems consisting of subsystems and components of different software lifecycles. This is true for most large, different kinds of enterprise systems, in which case the components are

NET system, these technologies are able to decouple resources and services, and which technology needs to depend on your application scenario.Personally, I prefer to use the WCF TCP pattern for enterprise intranet applications, which is highly eff
1. What is architecture?The common components abstracted from multiple products are organically linked to form an architecture.At present, we abstract the commonalities of technology, called sea.The sea architecture describes the elements contained in a software and the relationship between the elements to form a skeleton. On this basis, multiple products can be
The goal of SDN is to achieve an idealized enterprise network, separating network control from physical network topology, this creates an environment for sending traffic from the central management controller to all vswitches and routers. In a software-defined network environment, this software-based controller must have end-to-end monitoring capabilities for net

After you select the framework to be used for developing a Windows Phone 7 application, the application cannot use the functions provided by the other framework, that is to say, applications that use Silverlight framework as the basis for application development can still use the functions provided by xNa framework by referring to components. Otherwise, applications that use xNa framework as the basis for application development can also use the functions provided by Si
).ActiveMQACTIVEMQ is a sub-project under Apache. Similar to ZEROMQ, it is able to implement queues with agent and peer-to-peer technology. It is also similar to RABBITMQ, where a small amount of code makes it possible to implement high-level scenarios efficiently.Kafka/jafkaKafka is a sub-project under Apache and is a high-performance cross-language distributed publish/Subscribe Message Queuing system, and Jafka is hatched on Kafka, an upgraded version of Kafka. Has the following characteristic
development process definition; During the software design phase, the architect is responsible for the entire software architecture, key artifacts, interface and development policy design; In the coding phase, the architect becomes the consultant of the detailed designer and code writer, and regularly holds some technical seminars, technical courses, etc. integr

equivalent to overthrowing redo! If you do not overwrite the Redo, but modify the original code, the cost may be several or even dozens of times that of the original project.
There are three major changes to a system: business, system architecture, and program implementation.
1. Business Layer: There are many solutions to changes in requirements at the business layer. For example, the workflow management system uses Visual Process customization
An excellent architect always has a good balance between the merits of various solutions and the corresponding cost, which is the architect's rich experience and broad knowledge system. The message-based software construction model is the architect's necessary knowledge point, this article will describe the model's evolution process in detail. Remember the first time I was dealing with the company's software
