ABSTRACT
摘要
Reliability at massive scale is one of the biggest challenges we
face at Amazon.com, one of the largest e-commerce operations in
the world; even the slightest outage has significant financial
consequences and impacts customer trust. The Amazon.com
platform, which provides services for many web sites worldwide,
is implemented on top of an infrastructure of tens of thousands of
servers and network components located in many datacenters
around the world. At this scale, small and large components fail
continuously and the way persistent state is managed in the face
of these failures drives the reliability and scalability of the
software systems.
在亚马逊这个世界上最大规模的电子商务网站运营中,大规模下的可靠性是最大的挑战之一,即使是轻量的停电{中断}都会有很重要的财务影响和客户信任度冲击。
亚马逊平台为世界上许多站点提供服务,它是设计在成千上万的服务器和网络组件构成的许多数据中心的架构上,这些数据中心分布在世界各地。

This paper presents the design and implementation of Dynamo, a
highly available key-value storage system that some of Amazon’s
core services use to provide an “always-on” experience. To
achieve this level of availability, Dynamo sacrifices consistency
under certain failure scenarios. It makes extensive use of object
versioning and application-assisted conflict resolution in a manner
that provides a novel interface for developers to use.
