基于MemCached缓存技术Web应用设计与实现

An Web Platform Design and Implementation Methods Based On MemCached Scheme

为了解决Web应用庞大的并发访问量导致服务器承载大量压力，数据库响应恶化、网站显示延迟等问题，数据缓存技术应运而生。数据缓存技术是解决Web应用程序可扩展性和数据响应及时性的主要手段之一。Memcached作为目前最杰出的内存缓存技术用于解决系统的性质和访问压力，本文对在高负栽动态网站减轻服务器负载的原理及其应用场景，并对Memcached进行了生产环境的应用测试，提出了内存管理方式的优点、带来的问题和解决办法。

Concurrent traffic in order to solve the large Web application server to carry a lot of pressure, a database in response to deteriorating, delay problems, such as website display, data cache technology arises at the historic moment. Data cache technology is Web application scalability and data in response to one of the main means of timeliness. Memcached as by far the most outstanding memory cache technology, more and more application in this paper, starting from the background of Memcached, it is expounded in high load dynamic website to reduce the financial burden of database principle and application scenarios, and has carried on the simple to the Memcached application testing, analyzes the Memcached way of memory management advantages, problems and solutions.
