This paper introduces the implementation of a scalable TCP service based on Qt. This implementation is based on the requirements of C/S client-service cluster application. Connection monitoring, data transmission, data processing are carried out in a separate thread pool, depending on the specific tasks, can be arranged for monitoring, transmission, processing of the number of threads, in order to achieve high transmission load, high computational com

Original: http://agiledon.github.io/blog/2013/02/27/scalability-system-architecture-lessons/Recently, reading the articles of'll Larson introduction to the architecting System for scale, I feel very valuable. The author shares his architectural experience in designing scalable systems that he has harvested at Yahoo! and Digg. In my past architectural experience, due to the major involvement in the development of enterprise software systems, this enter

Translated from: http://kb.cnblogs.com/page/503460/Scalability is a software system processing capability of the design indicators, high scalability represents a kind of elasticity, in the system expansion process, can guarantee exuberant vitality, through the few changes, can achieve the overall system processing capacity growth.In the system design, fully consider the scalability of the system, on the one hand can greatly reduce the future maintenance costs, and help decision-makers on the ret

This article mainly introduces the use of ANGULARJS to achieve scalable page switching method, Angularjs is a popular JavaScript library, the need for friends can refer to the ANGULARJS 1.2 Through the introduction of pure CSS class switching and animation, in a single page application to create a page to the page switch becomes easier. With just one ng-view, let's take a look at a scalable approach that i

Label:The 14th chapter of Scalable Design data segmentation PrefaceThe extension implemented by MySQL Replication functionality is always limited by the size of the database, and once the database is too large, especially if it is too frequent to be supported by a single host, we still face an expansion bottleneck. At this point, we have to find other technical means to solve this bottleneck, that is, this chapter is to introduce the bad data segmenta

Box-flex flexible and scalable box ModelI have been focusing on PC-side development and have little access to self-adaptation. Generally, some css methods are used to directly solve some design problems until the current situation begins to change to pure mobile-side development, as a result, I started to get started with new features on the Mobile End. Today I will take notes on flexbox.The Flexbox layout module allows us to adapt ourselves to the de

it?Redis Scalable Cluster Build 1. Proactive replication avoids redis replication defects.Since the replication capabilities of Redis are flawed, we might as well abandon the replication capabilities provided by Redis itself, and we can use proactive replication to build our cluster environment.The so-called active replication refers to the data of Redis stored by the business side or through the agent middleware to write or write, the data of the mu

Inuit.css is a powerful and scalableCSSThe framework is also based on Sass, an object-oriented framework. Inuit.css is a naming convention based on the BEM style. It is very suitable for designers who want to focus on creativity rather than code and developers who like abstract and object-oriented methods. It provides you with design patterns rather than design decisions.Articles you may be interested in Metronic-Bootstrap-based responsive background management template Sharing of dry good
