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.

Design Continuums and the Path Toward Self-Designing Key-Value Stores that Know and Learn.

TL;DR: This work introduces the concept of design continuums for the data layout of key-value stores and presents the first continuum that unifies major data structure designs, i.e., Btree, B tree, LSM-tree, and LSH-table.

Reliability-Based Design Optimization for Cloud Migration

TL;DR: A reliability-based optimization framework, named ROCloud, to improve the application reliability by fault tolerance, and results show that by refactoring a small number of error-prone components and tolerating faults of the most significant components, the reliability of the application can be greatly improved.
