Large-scale website Architecture Evolution (8) Business splitting and Architecture Evolution In order to cope with increasingly complex business needs, large websites divide their businesses into different product lines and assign them to different development teams. This facilitates application expansion and maintenance. At the same time, different applications correspond to different databases, which red

Architecture scheme: the technical architecture scheme of a logistics screening single system with an average daily traffic of 0.5 million? System architecture For a logistics screening system with an average daily traffic of about 0.5 million, the system must respond within 3 seconds and have requirements on system reliability, stability, and scalability. what t

Recommended books and Android Architecture Based on android Architecture The architecture of the Android system can be divided into six parts. I recommend high-quality books for each part based on my own experience. 1. Android Application Android Developer Document, Pro Android, Professional Android Application Development, Google Android SDK Development example,

MongoDB (IV)-management architecture and mongodb Management Architecture We have introduced the basics of MongoDB. We recommend two websites here. You can check them and explain them in detail #. Let's take a look at MongoDB's data management and architecture. Well, let's take a look at the figure: See the following figure for details. I. Management, of course

How to Use the XML architecture set This example illustrates how to use the xmlschemacollection class used by xmlvalidatingreader for effective data verification. The xmlschemacollection class allows you to maintain the cache of multiple XML schema definition languages (XSD) and XML data simplified (XDR) architectures, which can be used when architecture is needed in the future. Although this class can sto

Our first step is to understand the three-tier architecture and issues and then see how MVVM solves these problems.Now, the feeling and the fact are totally different two things. When you see a block diagram of the three-tier architecture, you feel that the responsibilities of each layer are well-distributed. But when you actually write the code, you'll find that some layers are forced to do extra things th

Typically, a site's architecture comes with functional requirements, and the following five aspects should be considered:PerformanceAvailability ofElasticity ofScalabilitySecurityThe official explanation of performance performance, I will not say. To the user, is the system reaction speed is fast.For Web sites, performance issues are ubiquitous, and then there are a number of ways we can optimize performance.We used to go to the next one.In the browse

reads and writes very high and rarely changes , such as the product's category information, popular commodity information, and so on. In this way, when the application reads the data, it goes to the cache first, such as the cache is not or invalidated, and then fetched in the database, and re-written to the cache for the next visit. Therefore, it can improve the system performance, improve the data reading speed and reduce the storage access pressure . ③ Distributed Cache

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

What is a relational model? Use rows and columns in a two-dimensional table to maintain the data model. Oracle database architecture Database: database Oracle databases are p

Ios sdk architecture and IOSSDK Architecture Ios sdk Overview Preface: This article does not have much to do with architecture, but I have always felt that it is important to know what the SDK can provide for the overall architecture of IOS, and there will be fewer detours.

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
