Developer Newsletter: Why Tomorrow's Cassandra Deployments Will Be on Kubernetes
It seems we’ve crossed the line from people talking about deploying Cassandra on top of Kubernetes in production to actually doing it. Patrick McFadin (@PatrickMcFadin) interviewed several of these early adopters in this fascinating episode from the Accelerate online series.
- How does Sky UK stay grounded with Cassandra and Kubernetes | Episode 148 with Alan Gibson, Principal Software Engineer @ Sky UK.
- What you need to know to deploy Cassandra in Kubernetes | Episode 149 with Christopher Bradford, Product Manager @ DataStax
- Is self-driving data infrastructure our future? | Episode 150 with Raghavendra Prabhu, Sr. Software Engineer @ Yelp
Speaking of a common Cassandra Kubernetes operator, there’s already a Special Interest Group (SIG) hard at work! Check out the draft specification on Apache Cassandra Wiki site.
Community Highlights From cassandra.link
Our friends at Anant highlighted a few interesting posts that showed up on cassandra.link recently:
- Cassandra 4.0 Datacenter Security Enhancements - Anthony Grasso’s article describes how enterprises can better segment and secure data workloads.
- How to Deploy a Cassandra Cluster/Ring on Kubernetes + OpenEBS - With Cassandra + OpenEBS, avoid vendor lock-in with truly cloud-native storage on any Kubernetes distribution or vendor. Another testimony.
- CQL Data Modeler - Sebestian Estevez’s open-source tool for visualizing and creating Cassandra Stress tests is one of the best open secrets for folks new to Cassandra.
