architecture for dummies

I have set up a dial-up access platform in CERNET, developed it on the front-end platform of the load search engine in yahoo3721, and upgraded the architecture of large-scale community sows, at the same time, I have worked with and developed many large and medium-sized website modules. Therefore, I have accumulated some experience in large websites to cope with high-load and concurrent solutions. I can discuss this with you. A small website, such as

Transferred from: http://kb.cnblogs.com/page/539838/In the previous article, we discussed what a schema is. In fact, these basic concepts are very important for architecture, and most people think they are aware of the concepts they are accustomed to every day, but in fact they are subconscious and not active. For example, "What is a table?" "When I do training, I often take this example to ask you, answer all sorts of strange things." This actually l

Generally, the architecture is discussed in two ways: Development architecture and deployment architecture. The deployment architecture is to reduce the load of a single server through server load balancer, DNS round robin, SquID, and so on in the actual running environment of the developed program, so as to achieve pe

The previous article introduced the basic architecture diagram of Spring Cloud cloud service architecture, and we built the code based on the architecture diagram. Based on the concept of micro-service design, combined with spring Cloud's own service discovery, governance, configuration management, distributed and other excellent solutions, we use MAVEN technolog

The previous article introduces the integration of Spring Cloud cloud service architecture-Honghu Enterprise distributed micro-service Cloud architecture diagram, which we build according to the architecture diagram. According to the micro-service design idea, combining some excellent projects of spring cloud, such as service discovery, governance, configuration

1, three-tier architecture The three-tier architecture of the three-tier architecture (3-tier application) is to divide the entire business application into the presentation layer (UI), the Business Logic layer (BLL), the data Access Layer (DAL). The purpose of distinguishing hierarchy is to think of "high cohesion, low coupling". 1, the performance layer (UI): P

the authentication mechanism, so that the API should be usedYou do not need to specify a specific SASL mechanism. This API facilitates client and server applications so that applications can be based on the required security featuresSelect the mechanism you want to use, such as whether you are susceptible to passive dictionary attacks and whether you accept anonymous authentication. The Java SASL API also allows developers to create custom SASL mechanisms. The SASL mechanism can be installed us
