This is a guest post by Alessandro Pieri, Software Architect at Stream. Try out this 5 minute interactive tutorial to learn more about Stream’s API.
Originally built by Facebook in 2009, Apache Cassandra is a free and open-source distributed database designed to handle large amounts of data across a large number of servers. At Stream, we use Cassandra as the primary data store for our feeds. Cassandra stands out because it’s able to:
Shard data automatically
Handle partial outages without data loss or downtime
Scales close to linearly
If you’re already using Cassandra, your cluster is likely configured to handle the loss of 1 or 2 nodes. However, what happens when a full availability zone goes down?
In this article you will learn how to setup Cassandra to survive a full availability zone outage. Afterwards, we will analyze how moving from a single to a multi availability zone cluster impacts availability, cost, and performance.

Organizations that embrace a two-tier network architecture will be more likely to thrive in the future.
The judges have deliberated, our community has voted, and the results are in! We are happy to announce the top 5 submissions of the Docker 1.12 Hackathon.
In case you missed it, the theme of the hackathon was to build, ship, and run a distributed software application using a release candidate of Docker 1.12. We encouraged participants to hack the new features included in Docker 1.12, such as: Swarm Mode, Cryptographic node identity, Service API, and Build-in routing mesh.
