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.

Improving Cloud Service Resilience Using Brownout-Aware Load-Balancing

TL;DR: Experimental evaluation shows that the approach enables cloud services to remain responsive despite cascading failures, and when compared to Shortest Queue First (SQF), believed to be near-optimal in the non-adaptive case, the algorithms improve user experience by 5%, with high statistical significance, while preserving response time predictability.

Minimizing Commit Latency of Transactions in Geo-Replicated Data Stores

TL;DR: A lower-bound on commit latency is derived to develop a commit protocol, called Helios, that achieves low commit latencies and in a real-world deployment on five datacenters, Helios has a commit latency that is close to the optimal.
