business architecture software

[GOF95] is the first book on the software model and the most popular book on OO Design theory. Therefore, some people often use Design Pattern) the term "1" refers to any kind of pattern that directly processes the architecture, design, and program implementation of the software. Others stress that three different layers of patterns should be divided: Architectur

matured and understood and accepted by computer, and people began to consider the problem of object-oriented development. Until now, Object-oriented has become a very popular programming method, as well as the architecture of software design. The object-oriented approach has three main objectives: reusability, flexibility and extensibility, emphasizing objects ' abstraction, encapsulation, inheritance, an

The beginning of the architecture design determines the survival of the software products. "A good beginning equals half success." The initial architectural design is also the most difficult, the need to investigate the situation of similar products and technical characteristics, to understand the current world of this product can provide theoretical support and technical platform support. Combined with t

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 network resources and capacity. Through the netw

business is extracted, as an independent service, gradually form a stable service center, so that the front-end application can respond to the changeable market demand more quickly. At this point, the Distributed Service Framework (RPC) that is used to improve business reuse and consolidation is critical. Flow Computing Architecture when more and more services,

perform updates contained in the logs. Common architecture Methods: Master-Slave, Master-Master and master-Slave cascade, Master-Master-Cascade. Advantages: simple deployment, easy implementation, and yesMySQLThis feature allows you to easily switch between the master and slave nodes. You can use a third-party software or write a simple script to automatically switch between the master and slave nodes. Dis

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
