Dynamo: amazon's highly available key-value store

TLDR
D Dynamo is presented, a highly available key-value storage system that some of Amazon's core services use to provide an "always-on" experience and makes extensive use of object versioning and application-assisted conflict resolution in a manner that provides a novel interface for developers to use.
Abstract
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.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.

Exploiting Node Connection Regularity for DHT Replication

TL;DR: This paper proposes an alternative replication strategy that leverages nodes that exhibit regularity in their connection pattern and shows that this regularity-based replication strategy induces a systematically lower network usage than existing state of the art replication strategies.

Placement in Clouds for Application-Level Latency Requirements

TL;DR: This paper presents placement algorithms that exploit the Euclidean triangular inequality property of network topologies, and shows that Message Sequence Charts (MSCs), a widely-used mechanism for describing the execution of application procedures, can be naturally translated into the formalism of collective latency expressions.

Fast Distributed Transactions and Strongly Consistent Replication for OLTP Database Systems

TL;DR: Calvin is a practical transaction scheduling and data replication layer that uses a deterministic ordering guarantee to significantly reduce the normally prohibitive contention costs associated with distributed transactions, allowing near-linear scalability on a cluster of commodity machines.
