awesome-distributed-systems

A (hopefully) curated list on awesome material on distributed systems, inspired by other awesome frameworks like awesome-python. Most links will tend to be readings on architecture itself rather than code itself.

Bootcamp

Read things here before you start.

• CAP Theorem, Also plain english explanation
• Fallacies of Distributed Computing, expect things to break, everything
• Distributed systems theory for the distributed engineer, most of the papers/books in the blog might reappear in this list again. Still a good BFS approach to distributed systems.
• FLP Impossibility Result (paper), an easier blog post to follow along
• An Introduction to Distributed Systems @aphyr's excellent introduction to distributed systems

Papers

Must read papers on distributed systems. While nearly all of Lamport's work should feature here, just adding a few that must be read.

• Times, Clocks and Ordering of Events in Distributed Systems Lamport's paper, the Quintessential distributed systems primer
• Session Guarantees for Weakly Consistent Replicated Data a '94 paper that talks about various recommendations for session guarantees for eventually consistent systems, many of this would be standard vocabulary in reading other dist. sys papers, like monotonic reads, read your writes etc.

Storage & Databases

• Dynamo: Amazon's Highly Available Key Value Store Paraphrasing @fogus from their blog, it is very rare for a paper describing an active production system to influence the state of active research in any industry; this is one of those seminal distributed systems paper that solves the problem of a highly available and fault tolerant database in an elegant way, later paving the way for systems like Cassandra, and many other AP systems using a consistent hashing.
• Bigtable: A Distributed Storage System for Structured Data
• The Google File System
• Cassandra: A Decentralized Structured Storage System Inspired heavily by Dynamo, an now an open source
• CRUSH: Controlled, Scalable, Decentralized Placement of Replicated Data, the algorithm for the basis of Ceph distributed storage system, for the architecture itself read RADOS

Messaging systems

• The Log: What every software engineer should know about real-time data's unifying abstraction, a somewhat long read, but covers brilliantly on logs, which are at the heart of most distributed systems
• Kafka: a Distributed Messaging System for Log Processing

Distributed Consensus and Fault-Tolerance

• Practical Byzantine Fault Tolerance
• The Byzantine Generals Problem
• Impossibility of Distributed Consensus with One Faulty Process
• The Part Time Parliament Paxos, Lamport's original Paxos paper, a bit difficult to understand, may require multiple passes
• Paxos Made Simple, a more terse readable Paxos paper by Lamport himself. Shorter and more easier compared to the original.
• The Chubby Lock Service for loosely coupled distributed systems Google's lock service used for loosely coupled distributed systems. Sort of Paxos as a Service for building other distributed systems. Primary inspiration behind other Service Discovery & Coordination tools like Zookeeper, etcd, Consul etc.
• Paxos made live - An engineering perspective Google's learning while implementing systems atop of Paxos. Demonstrates various practical issues encountered while implementing a theoretical concept.
• Raft Consensus Algorithm An alternative to Paxos for distributed consensus, that is much simpler to understand. Do checkout an interesting visualization of raft
• Conflict-free Replicated Data Types presents an approach for Strong Eventual Consistency which as been applied in projects such as Riak, Redis and Akka. A great talk on the subject by Martin Kleppmann can be found here

Testing, monitoring and tracing

While designing distributed systems are hard enough, testing them is even harder.

• Dapper, Google's large scale distributed-systems tracing infrastructure, this was also the basis for the design of open source projects such as Zipkin, Apache SkyWalking, Pinpoint and HTrace.

Programming Models

• Distributed Programming Model
• PSync: a partially synchronous language for fault-tolerant distributed algorithms Video: Conference Video
• Programming Models for Distributed Computing
• Logic and Lattices for Distributed Programming

Verification of Distributed Systems

• Jepsen A framework for distributed systems verification, with fault injection @aphyr has featured enough times in this list already, but Jepsen and the blog posts that go with are a quintessntial addition to any distributed systems reading list.
• Verdi A Framework for Implementing and Formally Verifying Distributed Systems Paper

Videos

• Distributed Deep Dive interview series by Ably Relatime.
• Distributed Systems in One Lesson Distributed Systems in One Lesson by Tim Berglund

Courses

• Reliable Distributed Algorithms, Part 1, KTH Sweden
• Reliable Distributed Algorithms, Part 2, KTH Sweden
• Cloud Computing Concepts, University of Illinois
• CMU: Distributed Systems in Go Programming Language
• Software Defined Networking , Georgia Tech.
• ETH Zurich: Distributed Systems
• ETH Zurich: Distributed Systems Part 2, covers Distributed control algorithms, communication models, fault-tolerance among other things. In particular fault tolerance issues (models, consensus, agreement) and replication issues (2PC,3PC, Paxos), which are critical in understanding distributed systems are explained in great detail.
