The transformation of Google architecture from failover system to multi-homed architectureRunning a single data center is difficult, so switch to a dual datacenter if you need to support multiple data centers in different geographies. Google has a thoughtful, thought-provoking paper that describes the process-"large-scale high availability: Building Google's advertising data infrastructure."The main idea is that a typical failover

Like you just started building a house because of the low-level popularity of the roof bungalows This is a kind of architecture (v5t) and then this cottage structure you can design a separate bathroom style this is called the ARM7 kernel and then others (Chip design company) want to build the house to buy you this drawing to cover and then after a period of time Some people think that the light independent bathroom is not enough ah, I also want to hav

If you are not familiar with MyBatis, please refer to the MyBatis official documentation, which is of great benefit to understanding its architectural design and source code analysis.I. OverviewMyBatis is not a complete ORM framework, its official homepage is so introduced to its ownData Mapper Framework Object using Simplicity is Object relational mapping tools.And in its official documentation, "What's Mybaits" says is class for MyBatis eliminates almost all of the JDBC code and manual setti

Business expansion: three-tier architecture and three-tier architecture 1. What is the three-tier architecture first to see the title? The three-tier architecture is actually: ① Presentation layer: receives user input and presents the output to the user, And access security verification, and correctness of the input d

1. Architecture and framework design levels are different like hardware design, software design is divided into different levels. Typical software design levels are as follows: In this figure we can see that the framework is between micro-architectures and application level. DEISGN patterns is a micro-architectures-level design, and the framework is formed by multiple design pattern and other micro-architectural elements. The objectclasses, Micro-arch

1. Software Architecture Style A core issue of software architecture design is the ability to use repetitive architectural patterns, that is, the ability to achieve architecture-level software reuse. This means that the same architecture can be used in different software systems. For this purpose, scholars began t

Large Web site technology Architecture (i)--large-scale website architecture evolutionEach pattern describes a problem that recurs around us and the core of the solution to the problem. This way, you can use the program again and again without having to do repetitive work.The so-called site architecture model is to solve the large-scale web site with high concurr

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 service architecture-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 management, r

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
