Developer Newsletter: The Convergence of Cassandra and Kubernetes

With Kubecon North America happening this week, there’s been a lot of discussion about managing data in Kubernetes, and we’ve been excited to share new projects that help with both running Apache Cassandra™ on Kubernetes as well as accessing Cassandra from applications deployed on Kubernetes.  

K8ssandra provides a production-ready platform for running Cassandra on Kubernetes. This includes automation for operational tasks such as repairs, backups, and monitoring. K8ssandra is delivered as a collection of Helm charts that assembles the tools that the Cassandra community has rallied around, including the Cass-operator (Kubernetes operator), Cassandra Reaper for repairs, Cassandra Medusa for backups, and Prometheus and Grafana for metrics collection and visualization.


Many of you joined us for the Kubecon workshop, “Putting Cassandra on Automatic with Kubernetes,” where we provided hands-on experience with K8ssandra. If you missed it, the resources are available on GitHub, and you can watch the replay on YouTube. You can also visit for more hands-on learning and resources.

Of course, there are plenty of developers looking to deploy applications on Kubernetes that attach to a managed version of the database. The Astra Service Broker, which was also announced this week, leverages the Open Service Broker API to let you provision and consume DataStax Astra databases alongside your applications inside Kubernetes and Cloud Foundry. This blog post walks you through the process of spinning up a sample application and connecting to your free Astra database


Yes, this week was all about Kubecon and Kubernetes, which reminds us of our favorite tweet of the week. No, we haven’t changed our name, but it’s not the worst rebranding idea we’ve heard… :) 

New Certification Program

  • We’re developing a new certification program for running Cassandra on Kubernetes. Check out our certifications page for details and to sign up for email updates.
