1. First stage: Single Server architectureThis stage is our initial stage, for example, when we started a business, we just bought a cloud host.At this stage, in order to save costs, we put all the applications, databases, files on this server.Then, the cost of CPU or memory is also used in the development phase to take the least acceptable cost, and then start our server development path.2. Phase II: Separation of application services and data ServicesWith the first launch of the site, if our s

Summary of my Architecture Experience (II)-I have already thoroughly introduced some experience in L3 architecture. Now, let's take a closer look at what I understand with a lower scale. I. Three-layer architecture 2. responsibilities at all levels of the system1. The UI (User Interface) layer is responsible for data presentation and collection. The data collecti

optimization StrategyAccording to the website layered architecture, can be divided into web front-end performance optimization, Application server performance optimization, Storage server performance optimization.2.1 Web front-end Optimization 2.1.1 Browser access optimization Reduce the number of HTTP requests, mainly by merging Css,javascript, pictures. Use browser-side caching. At some point, static resource file writing needs to be a

Summary: Development tools 1.Eclipse IDE: Using MAVEN project management, modular. 2. Code generation: Through the interface mode simple configuration, automatically generate the corresponding code, currently includes three ways to generate (add and revise): Single table, one-to-many, tree structure. After the generated code, if you do not need to pay attention to the degree of beauty, after the build can be used. Technology selection (only part of the technology) 1, backend service framework: D

This book brings together over 30 years of experience from ebay, VISA, Salesforce.com, and Apple, explaining the proven approach to information technology expansion, elaborating on the smooth expansion of products and services needed, and updating the extended strategy on the 1th edition , technology and cases.For technical and non-technical d

Write at the beginning: Have met several times netizens ask, plug-in in the end is how to achieve. So the germination of their learning structure in the process of learning the knowledge point to write a series of articles, so that unfamiliar users of the concept and realization of a simple understanding, but also to give themselves a training text, collation knowledge and accept everyone to correct the opportunity. Limited to their own level, the article inevitably has a lot of mistakes, welcom

Take advantage of the holiday, finally the "large Web site technology architecture Core Principles and Case Analysis" this book read. This book gave me a new understanding of the site architecture, the whole book is more simple and easy to understand, so that people who get started more easily understood. It introduces a lot of technical concepts. To reverse proxy and CDN and so on. I write two articles, is

Summary of. NET Logical Layered Architecture,. net layered architectureI. Basic Knowledge preparation: 1. layer principles: (1) Each layer is called by the upper layer in interface mode.(2) The upper layer can only call the lower layer.(3) Dependency can be divided into loose interaction and strict interaction. 2. Business Logic classification: (1) application logic.(2) domain logic. 3. layer used: (1) presentation layer (User Interface Layer): domain

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 led to the structure of the time, the different roles

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
