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:Â
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.read more

MixT: a language for mixing consistency in geodistributed transactions
Matthew Milano,Andrew C. Myers +1 more
TL;DR: This work introduces a new abstraction: mixed-consistency transactions, embodied in a new embedded language, MixT, that retain much of the speed of weak consistency, significantly outperforming traditional serializable transactions.

Querying combined cloud-based and relational databases
Minpeng Zhu,Tore Risch +1 more
TL;DR: This work has developed a system called BigIntegrator to enable general queries that combine data in cloud-based data stores with relational databases, which is general and extensible to integrate data from different kinds of data sources.

SNC-Meister: Admitting More Tenants with Tail Latency SLOs
TL;DR: SNC-Meister improves upon the state-of-the-art DNC-based systems by using a new theory, Stochastic Network Calculus (SNC), which is designed for tail latency percentiles, rather than the adversarial worst-case DNC latency.
Patent
Fault tolerant and load balanced routing
TL;DR: In this paper, the authors describe techniques for balancing traffic load for networks configured in multi-rooted tree topologies, in the presence of link failures, and calculate maximum flows for subgraphs that incorporate effective link capacities on links between source and destination nodes.

Chord: A scalable peer-to-peer lookup service for internet applications
TL;DR: Results from theoretical analysis, simulations, and experiments show that Chord is scalable, with communication cost and the state maintained by each node scaling logarithmically with the number of Chord nodes.

Time, clocks, and the ordering of events in a distributed system
TL;DR: In this paper, the concept of one event happening before another in a distributed system is examined, and a distributed algorithm is given for synchronizing a system of logical clocks which can be used to totally order the events.

Pastry: Scalable, Decentralized Object Location, and Routing for Large-Scale Peer-to-Peer Systems
Antony Rowstron,Peter Druschel +1 more
TL;DR: Pastry as mentioned in this paper is a scalable, distributed object location and routing substrate for wide-area peer-to-peer ap- plications, which performs application-level routing and object location in a po- tentially very large overlay network of nodes connected via the Internet.
