of the introduction, the work requires you to be based on the specific business scenarios for the architecture design.The above is the e-commerce website Architecture case sharing a total of three, from the e-commerce website needs, to the single-machine architecture, gradually evolved into a common, reference to the distributed

The specific analysis is as follows: Before 3.13 Many projects all use the front and back common class, under Lib/action creates the baseaction as the public inherits

Today, my colleague asked me what is the use of web service in the system? What is the difference between it and the general direct writing on the client? What are the advantages? It is really interesting to answer this question. Since I have asked this question, it means that there are some preconditions for not reaching an agreement. It is easy to explain the technology itself. Therefore, we should first clarify the background of recommending the use of the SOA

High concurrency Server Architecture Evolution of large website architecture Three server requirements: High Performance: rapid response to a large number of requests High Availability: uninterrupted, automatic failover occurs, which is called fail over (Failover) Scalability: Cross-machine communication (TCP) In addition, any network system structure can be abstracted into a C/S

Recently, the company requested that the architecture of a product be changed from two layers to three layers (the reason is: For security review, a three-layer architecture is required because the database port is only open to the server ), when I heard it, I fainted. The initial architecture of the product was three layers. Later, due to various requirements du

1. The software development process is divided into several steps: defining issues, requirements analysis, planning architecture, software architecture (or higher-level design), detailed design, coding and commissioning, unit testing, integration testing, integration, system testing, assurance maintenance2. Build activities include: detailed design, coding, commissioning, integration, developer Self-test, u

: This article mainly introduces the first chapter: the overall architecture of the high-performance Web macro architecture. if you are interested in the PHP Tutorial, refer to it. The following blog posts will provide you with a relatively simple macro-architecture solution and detailed implementation and deployment tutorials. The preceding cluster environm

Some problems occurred recently when determining the project architecture model.ArticleAnd design. The following documents and designs are recorded for future Summarization: 1. enterprise application architecture model-patterns of enterprise application architecture Trial (enterprise application architecture patterns

In the technical documentation, we often find that topology, architecture, and struct are not strictly differentiated. Sometimes we can see that a topology becomes a pure echure, and sometimes a struct becomes a pure echure.From a rigorous point of view, how should we define and distinguish them for correct use? My personal understanding is as follows: 1. the focus of topology is network deployment, such as the distribution of data centers. architechu

Advantages and disadvantages of C/s architecture:Advantages1. Because the client is designed independently, it can realize the personalization2. Because the client needs to be installed, it can not need to be installed and loaded repeatedly3. Because the client is independently developed, it has the ability to design the client securely4. If you encounter different operating systems, you need to develop a set of clients for different operating systemsDisadvantages1. Because the client is not req

The last section of the "large-scale Web site Architecture Evolution", today to talk about the structure of the model, what is the model? Each pattern describes the core of a problem and problem solution that repeats itself around us, so that you can reuse the program over and over again without having to do repetitive work, and the key to visible mode is repeatability.The goal of the Web site architecture

One, what is high concurrency High concurrency is one of the factors that must be considered in the architecture design of the Internet Distributed system, it usually means that the system can handle many requests simultaneously in parallel through the design. Some commonly used indicators of high concurrency are response times (Response time), throughput (throughput), query rate per second QPS (query/Second), number of concurrent users, etc. Respon

The overall system architecture is very important, but its expressions are different. The following describes several common system architecture modes for your reference: Assf (access-Service (BIZ)-standard-fundation) Mode: Access-Service (business function)-standard-basis, which can be expressed at all levels of the system architecture. However, the application

Next, we used the field-driven development approach, using the congestion model to enjoy his benefits, but also have to face the drawbacks he brings. This disadvantage is amplified under the distributed microservices architecture.Transactional consistencyThe issue of transactional consistency is not a big problem under monolithic, but under microservices it is deadly, and we review the so-called acid principleatomicity– atomicity, changing the state of the data is either done together or failed

The MVC was shot last time, and the three-tier architecture was shot again this time. I felt like a Red Guard with a big text everywhere ^_^, but I cannot tell it clearly, I hope my bricks will attract more incisive explanations. Speaking of the layer-3 architecture, MVC is actually caused by seeing a man show me his outline design book, because this gentleman can represent many beginners developers and mis
