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.

A Conflict-Free Replicated JSON Datatype

TL;DR: This paper presents an algorithm and formal semantics for a JSON data structure that automatically resolves concurrent modifications such that no updates are lost, and such that all replicas converge towards the same state (a conflict-free replicated datatype or CRDT).

Zoolander: Efficiently Meeting Very Strict, Low-Latency SLOs.

TL;DR: Zoolander is presented, a key value store that meets strict, low latency service level objectives (SLOs), and scales out using replication for predictability, an old but seldom-used approach that uses redundant accesses to mask outlier response times.

Hyperloop: group-based NIC-offloading to accelerate replicated transactions in multi-tenant storage systems

TL;DR: HyperLoop is presented, a new framework that removes CPU from the critical path of replicated transactions in storage systems by offloading them to commodity RDMA NICs, with non-volatile memory as the storage medium and demonstrates that popular storage applications can be easily optimized using these primitives.
