Distributed Systems links

pg-distrib-logoA few years ago, while researching Zookeeper for a project I was working on, I realized that there was a whole field Computer Science, Distributed Systems, that I was totally unfamiliar with. That started a journey of discovery that’s been very rewarding.   In response to a question on the Akka mailing list I put together a list of links to Distributed Systems resources.  I’ve been meaning to translate that email to a blog post for a while.

To start off I would definitely recommend checking out a talk that Jonas Boner from Typesafe gave at Strange Loop last year called The Road to Akka Cluster and Beyond (slides).

Implementation-oriented books that I would recommend for developers are:

These are all filled with practical advice for building real-world distributed systems.

One thing I found is that there is a big gap between academic and industry knowledge right now.  This is discussed in a post on Henry Robinson’s excellent Paper Trail blog where he provides a guide to digging deeper both on the academic side and by reading research papers written by industry leaders like Google, Yahoo, etc.   Definitely read the links in the “First Steps” section.  The gap is also the topic of a post on Marc Brooker’s blog.  Besides papers he links to some other good people to follow like Aphyr and Peter Bailis.  Two blogs that review Distributed Systems papers are the Morning Paper and MetaData.  I also recommend following Brave New Geek, Ben Stopford and Kellabyte, and the High Scalability and Highly Scalable blogs.

Working to fill the gap are a few books (most are in progress):

Essential ACM Queue articles

Notable blog posts

Online Courses

I recommend getting familiar with the CAP Theorem.  You’re going to run into it all over the place.

Zookeeper is a Consensus (or Coordination) system.  Consensus is a major topic in theoretical and practical distributed systems and is what got me started digging into distributed systems originally.  To start getting familiar with Consensus I recommend:

On the academic textbook side, I have these on my stack to read:

This is just the tip of the iceberg.  Besides consensus, other distributed systems topics that I’ve found interesting include distributed databases, group membership, gossip protocols (used in Akka, Cassandra and Consul), time and clocks, and peer-to-peer systems.
