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.

Systems and methods for managing distributed database deployments

TL;DR: In this paper, the authors provide a database as a cloud service that eliminates the design challenges associated with many distributed database implementations, while allowing the client's input on configuration choices in building the database, so that clients can simply identity a number of database nodes, capability of the nodes, and within minutes have a fully functioning, scalable, replicated, and secure distributed database in the cloud.

The Homeostasis Protocol: Avoiding Transaction Coordination Through Program Analysis

TL;DR: In this article, the authors describe a new approach to achieving strong consistency in distributed systems while minimizing communication between nodes, which allows the state of the system to be inconsistent during execution, as long as this inconsistency is bounded and does not affect transaction correctness.

Trash day: coordinating garbage collection in distributed systems

TL;DR: This paper proposes a Holistic Runtime System, a distributed language runtime that collectively manages runtime services across multiple nodes that is effective both in reducing the impact of GC pauses on a batch workload, and in improving GC-related tail-latencies in an interactive setting.
