architecture for dummies

This article is the nineth of a rambling architecture column, in which Kevin takes fire as a starting point and introduces the relationship between technology, business and architecture in depth. As the authors have said, technology has always been created in the context of human settlement of the demands of the business, and the aim is to gain greater and better benefits.One day to eat with friends just to

1.HDFS Storage Architecture(1) HDFS Architecture--File1) The file is cut into chunks (default size 64M), in blocks, each block has multiple copies stored on different machines, the number of copies can be specified at the time of file generation (silentRecognition 3)2) NameNode is the master node that stores metadata such as file name, file directory structure, file attributes (generation time, number of co

used to simplify system-level software development, such as operating systems, user interfaces, and language processing. Typical examples include macapp and Microsoft's MFC.(2) middleware integration framework. It is used to assemble distributed applications and components. Typical examples include Microsoft's DCOM, Alibaba oft's RMI, And OMG's CORBA.(3) enterprise application framework. It is used in various application fields, such as telecommunications, manufacturing, and finance.It can be d

Research on layer-3 Architecture Concept of three-tier architecture User Interface presentation layer (USL) Business logic layer (BLL) Data access layer (DAL) Bll separates usl from dal and adds Business Rules Role of each layer 1: Data access layer: mainly refers to the operation layer for raw data (in the form of storing data such as databases or text files), rather than raw data, th

C/S architecture C/S architecture can also be seen as a fat client architecture. Because the client needs to implement the vast majority of business logic and interface display. In this architecture, the part of the client takes a lot of pressure because the display logic and transaction processing are included, to me

Anjuke Android project Architecture Evolution and android Architecture Evolution After three years of employment as an anjuke, the engineer and Team Leader witnessed the development of the Android Team. Therefore, sharing these records is a summary of some of your work over the past three years. I hope to help you and give you valuable suggestions.I. Merger of the three networks Three years ago, when I join

Address of this articleOriginal addressFor the understanding of large-scale web site technology, we can explain the technical points of the website architecture from the aspects of system performance, usability, scalability, extensibility and security from the aspects of the Organization of architecture technology and the structure elements as dimensions. There is another, more intuitive way of organizing,

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

The root of software complexity comes from the complexity of thinking. Three-tier architecture look at three-tier DDD Implementation detailed architecture look at Code Business Domain persistent layer (data layer) testing and use example complete code download Handy weapon Library: Fluent nhib.pdf Nunit Git (GitHub) For the tools involved in this article, see the previous article: My.

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

System architecture and software architecture Further analysis, whether in the field of construction engineering or other engineering fields (including computer science), intuitively we can find out what they have in common: that is to say, from a philosophical point of view, they are all creations, evolution, and development of mankind in order to overcome the inherent fear.What do humans fear?We can note

Let's look at the classic 3-tier architecture and see: The platforms involved can be: Ruby on Rails, Java EE, ASP, PHP, ColdFusion, Perl, Python The data transfer using protocol between tiers can be: SNMP, CORBA, Java RMI,. NET Remoting, Windows communication Foundation, sockets, UDP, Web services, etc. The 3-tier architecture we often talk about is the N-tier architec
