The network is reliable. Latency is zero. Bandwidth is infinite. The network is secure. Topology doesn't change. There is one administrator. Transport cost is zero. The network is homogeneous.…

Some concepts as blow: Welcome to Akka, a set of open-source libraries for designing scalable, resilient systems that span processor cores and networks. Akka allows you to focus on meeting business needs instead of writing low-level code to provide r…

Serialization and deserialization are bottlenecks in parallel and distributed computing, especially in machine learning applications with large objects and large quantities of data.…

Gwen Shapira, SA superstar and now full-time engineer at Cloudera, asked a question on Twitter that got me thinking. My response of old might have been “well, here’s the FLP paper, and here’s the Paxos paper, and here’s the Byzantine generals paper…”…

add by zhj: 文章有点老了,2009年的,到现在已经六年了,不过还是很有参考价值的. 另外,吐槽一下PUT method,竟然允许用户用实例号来创建,靠,这也行,实例号还是后台来定义比较方便,由前端指定那会把实例号搞乱啊.我个人还是喜欢用PUT来更新,如果资源不存在,也不允许他创建资源. 翻译原文:RESTful HTTP的实践 本文对RESTful HTTP的基础原理做了一个概览,探讨了开发者在设计RESTful HTTP应用时所面临的典型问题,展示了如何在实践中应用REST架构风格…

Distributed programming is the art of solving the same problem that you can solve on a single computer using multiple computers. Scalability 处理每件事情都需要注意它的规模,如果规模达到一定程度,处理的难度明显加强.例如你可以计算出一个房间中的人数,但是很难计算出一个国家的人数.在一个可扩展的分布式系统中,系统从小变大,但是相关性能没有变差. 比如在单机文件…
