, the most common is the business sub-Library, the different business databases deployed on different physical servers.(8) The architecture of level eight Web sites: using NoSQL and search engines to provide better support for scalable distributed features, the application server accesses a variety of data through a unified data access module, alleviating the hassle of application management of many data sources.(9) Level nine Web site

Recently just finished reading Hae's "large Web site technology architecture-core Principles and case analysis", the key content of each chapter made some notes, in order to deepen the impression and future review.First, the characteristics of large-scale website software systemhigh concurrency, large flow: need to face high concurrent users, large traffic access. High Availability: system 7x24 Hour service

First, website attack and defense Attack: 1. XSS attack: Dangerous character escapes, HttpOnly 2. Injection attack: Parameter binding 3, CSRF (cross-site request forgery): Token, verification code, Referer Check 4. Other vulnerability attacks Error Code HTML annotations File Upload Path traversal Defense: 1. Web Application firewall: modsecurity 2. Website security vulnerability Scan Second, information encryption technolo

Opening and closing principle OCP (Open for extension,closed for modification). The core idea of open and close principle is that an object is opened to expansion and closed to modification. In fact, the opening and closing principle means that changes to the class are made by adding code rather than altering the existing code. In other words, once the software developer writes out the code that can be run, it should not change it, but to ensure that it can continue to run, how to do this? Th

the same result, that is, the service is idempotent. Service idempotent is sometimes natural, such as setting the user's gender as a male, regardless of how many times it is set, the result is the same, but for operations such as transfer transactions, the problem becomes complex and requires information such as transaction numbers. For service invocation validation, only valid actions can continue. Study Note 6: The core Principles and

the compilation phase, Complete the code implantation before compilation, and ensure that the embedded code can be compiled. For more information about piab, see the piab series enterlib piab deep analysis by artech. Vi. Summary in this Chapter This chapter describes in detail how to implement the specifications and principles of software design. The focus is separated by object-oriented and object-oriented programming, and the

Furthermore, if customers can discover and BIND available services, the IT systems behind these services can provide greater flexibility.However, to achieve a strong and flexible architecture, a new method is required, which is a daunting task.

statement At last ObjectiveOracle architecture, which describes the underlying implementation principles of Oracle RDBMS, is the basic theory of Oracle dba** tuning and debugging. An in-depth understanding of Oracle architecture allows us to go farther on Oracle's path. Understanding the architecture of

The building code stipulates that the bedroom window should be at least 30 inches high, 20 inches long, so that in the event of a fire, the person can pass; The yellow seat on the bus is for the old and the sick, and the child is often said to be free, but it must intervene for safety. These are the principles of life that need to be obeyed. When it comes to architecture, does it need to follow some

server, where the static resources of the site are cached, without the need to continue to forward the request to the application server, directly back to the user Local cache. The hotspot data is cached locally on the application server, and the application can be accessed directly in local memory without having to access the data tier Distributed cache. The data is stored in a dedicated distributed cache cluster, and the application server accesses the cached data over network traffic
