Let's lay the groundwork for creating our Cassandra cluster. Kubernetes scales operations for Apache Spark, Apache Kafka, Apache Flink, Akka, and Presto―and all work really well with Cassandra. DataStax had already launched an operator for Kubernetes in March this year, but found when building Astra, its DBaaS, that "there's a lot more going on to run Cassandra successfully [in Kubernetes] than just an operator," McFadin said. The best approach is with Vim. Hopefully much of the prior work can be leveraged in the combined effort. Kubernetes is a technology that can match well with Cassandra’s capabilities because it shares the features of being linearly scalable, vendor-neutral and cloud-agnostic.
