eBay转储microsoft for java，每天实现10亿次页面浏览量

本文介绍了eBay转储microsoft for java，每天实现10亿次页面浏览量的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 不久之后，eBay决定从后端的Microsoft / .NET / Windows 架构切换到J2EE架构，这可能解释了为什么他们的 java后端每天最多可处理10亿次页面浏览量！有趣的 的事情是eBay是.NET开始时的主要案例研究之一，当时还有一些关于它的炒作。 关于一些java案例研究的有趣帖子： http://weblogs.java.net/pub/wlg/268 我喜欢通过案例研究。他们可以教你很多关于 该怎么做，什么不该做，什么是流行的等等。所有那些有用的 设计模式来自分析大量的案例研究并查看 的工作情况;有时，更重要的是，什么都行不通。 所以今年我决定在找到它们时开始列出案例研究。 一个很好的起点是JavaOne，那里有很多非常大的案例 研究。所以他们在这里。我的亮点：eBay 每天设置10亿次页面浏览量;巴西国民 健康每月处理1亿个门诊手术; 2400万 台湾健康保险使用的Java卡; Capital One Financial 每月处理8000万笔交易。 类似的J2ME统计数据，请访问： http://www.blueboard.com/j2me/stats.htm http://www.blueboard.com/j2me/why.htm 解决方案 asj写道： 一段时间后，eBay决定从Microsoft / .NET /切换Windows 后端到J2EE的架构，这可能解释了为什么他们的后端java后端每天最多可以处理10亿次页面浏览量！有趣的是，eBay是.NET开始时的主要案例研究之一，当时还有一些关于它的炒作。 关于一些java的有趣帖子案例研究： http://weblogs.java.net/pub / wlg / 268 我喜欢通过案例研究。他们可以教你如何做什么，不该做什么，什么是流行的等等。所有那些有用的设计模式来自分析大量的案例研究和看什么工作;有时，更重要的是，什么都行不通。 所以今年我决定在找到案例研究时开始列出案例研究。这是一个很好的起点是JavaOne，其中提供了大量的大案例研究。所以他们在这里。我的亮点：eBay 每天构建10亿次页面浏览量;巴西国民健康每月处理1亿门诊手术;台湾健康保险使用的2400万张Java卡; Capital One Financial每月处理8000万笔交易。 当然，您的隐含结论是这些公司无法做到这一点/> 如果他们使用其他技术，则处理相同的流量。 当然，没有证据支持这个结论，因为这些公司 没有使用其他技术。 您可以从引用的案例研究中得出的唯一结论是，他们 正在实现他们使用他们使用的技术实现的性能。不再。不能少。 可以找到很多类似的信息< url： http://www.microsoft.com/net/casestudies/ />，但同样，所有这些案例 研究表明是使用 技术选择所获得的性能和成本降低，如果所涉及的公司使用了其他技术，它没有说明这些数字会是什么样子。 。 Monster主要使用ASP代码，并将Alta Vista用作求职者和招聘人员的主要搜索引擎。通常，该网站每天处理200万到300万独立用户，每天提供40到45亿美元的页面浏览量，平均每个流量大约200兆位。 /> 在黄金时段的第二个上午11点之间到下午4点左右东部时间。然而， Monster跟踪了大约10,000个网络流量的峰值？网页处理了吗？每秒b $ b $。 以上是完全没有意义的（是任何Java案例研究性能 数字），因为它们可能能够使用PHP，ColdFusion处理相同数量的页面 ，或者Java，我们根本就不知道，因为 他们不使用其他技术。 至于缺乏炒作，它可能已经安静了，但似乎有很多实施该技术的公司。最终，这不是技术在贸易杂志中产生的噪音，而是使用它的人，以及它的用途。它似乎公司已经评估了这些选择，并且正在实施为其环境实施最佳技术的 业务。 - | Grant Wagner< gw ***** @ agricoreunited.com> 2003年7月28日星期一17:58:39 +0000，Grant Wagner写道： asj写道： 一段时间后，eBay决定改用Microsoft / .NET / Windows 架构J2EE的后端，这可能解释了为什么他们的java后端每天最多可处理10亿次页面浏览量！有趣的是，eBay是.NET开始时的主要案例研究之一，当时还有一些关于它的炒作。 关于一些java的有趣帖子案例研究： http://weblogs.java.net/pub / wlg / 268 我喜欢通过案例研究。他们可以教你如何做什么，不该做什么，什么是流行的等等。所有那些有用的设计模式来自分析大量的案例研究和看到什么工作;有时，更重要的是，什么都行不通。 所以今年我决定在找到案例研究时开始列出案例研究。这是一个很好的起点是JavaOne，其中提供了许多非常大的案例研究。所以他们在这里。对我来说非常重要： eBay每天设置10亿次页面浏览量;巴西国民健康每月处理1亿门诊手术;台湾健康保险使用的2400万张Java卡; Capital One Financial每月处理8000万笔交易。当然，您的隐含结论是，如果他们使用某些公司，他们将无法处理相同的流量其他技术。当然，没有证据支持这一结论，因为这些公司没有使用其他技术。 您可以从引用的案例研究中得出的唯一结论是他们正在通过他们正在使用的技术实现他们所实现的性能。不再。不能少。 可以找到很多类似的信息< url： http://www.microsoft.com/net/casestudies/ />，但同样，所有这些案例研究表明，所获得的性能和使用技术选择，它没有说明数字看起来是什么样的，如果涉及的公司使用了其他技术。 Monster主要运行ASP代码并使用Alta Vista是求职者和招聘人员的主要搜索引擎。通常，该网站每天处理200万到300万独立用户，每天提供40到4500万页面浏览量，在黄金时段每秒平均有大约200兆位的流量？上午11点到下午4点左右东部时间。但是，Monster跟踪了大约10,000个网络流量的高峰？网页每秒处理一次。 以上是完全没有意义的（是任何Java案例研究性能数字），因为它们可能能够提供使用PHP，ColdFusion或Java处理的相同数量的页面，我们根本就不知道，因为它们没有使用其他技术。 至于缺乏炒作，它可能已经安静，但似乎有很多公司实施该技术。最终，它并不是技术在贸易杂志中所产生的噪音，它是谁使用它，以及为什么。似乎公司已经评估了这些选择，并且正在开展为其环境实施最佳技术的业务。 you 在那里说服我们的工作很辛苦......你不能忽视的一个重要事实就是他们不再使用.NET了...... > Gosh对他们来说一定是一件昂贵的事情......所有 努力走向1 Redmond Way ...那么多你的努力吹嘘.NET 技术...抛到信息高速公路的边缘 就像昨天的垃圾... 今天还要重新启动你的ms-windows计算机??? < http://makeashorterlink.com/?X27F52465> Mr。盖茨今天承认该公司的错误报告服务表明，所有基于Windows的计算机中有5％现在每天崩溃的次数超过两次。 Grant Wagner写道： paul cooke写道： 你有一份艰苦的工作说服我们......你不能忽视的一个重要事实就是他们不再使用.NET了...... 天哪这一定是一件昂贵的事情。他们已经完成了......所有的努力都是为了实现一趟Redmond Way ...那么多为您自豪的.NET 技术......悄悄走向信息高速公路的边缘 首先，我不确定他们曾经使用过.NET，我相信这个转换是先于任何.NET解决方案的实现。即使他们有一个完全运行的.NET站点并将其换成Java解决方案，我也会有兴趣看到表明它已经完成的源代码，因为.NET无法使用处理负载。 eBay一直在实施.net的很多部分，包括 护照。他们也一直沉重地进入窗户，这就是为什么鲍尔默在发生这种情况时非常生气的原因。那么我相信IBM的websphere在eBay的一系列测试之后击败了微软和太阳。 它肯定搞砸了微软，因为eBay被大肆吹嘘非常非常好地作为微软的最大支持者.net ... 当然，其他值得注意的公司转换为广泛使用.NET后的例子，我最近指出的一个例子是 Cerner： http：//www.infoworld.com/article/03 / ... cerner2_1.html awhile back, eBay decided to switch from a Microsoft/.NET/Windowsarchitecture on the backend to a J2EE one, which might explain why theirjava backend will handle up to 1 BILLION page views a day! the funnything was eBay was one of the major case studies for .NET at thebeginning, when there was still some hype about it.interesting post about a few java case studies: http://weblogs.java.net/pub/wlg/268"I love looking through case studies.

Gosh that must have been an expensive thing for them to have done... all that effort to go the 1 Redmond Way... so much for your much vaunted .NET technology... tossed out onto the verge of the Information Superhighway like yesterday''s rubbish... First of all, I''m not sure they ever used .NET, I believe the switch was made prior the implementation of any .NET solutions. Even if they had a fully functioning .NET site and swapped it out for a Java solution, I''d be interested to see sources that indicate it was done because .NET could not handle the load.eBay had been implementing a lot of the parts of .net, includingpassport when this happened. they also had been heavily into windows,which is why ballmer had been so angry when this happened. then ibelieve IBM''s websphere beat out both microsoft and sun after a seriesof tests eBay did.it sure screwed microsoft though, since eBay was trumpeted very VERYloudly as the biggest backer of microsoft''s .net...there are of course, other notable examples of companies switching toj2ee AFTER using .NET extensively, one recent example i pointed out wasCerner: http://www.infoworld.com/article/03/...cerner2_1.html 这篇关于eBay转储microsoft for java，每天实现10亿次页面浏览量的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
