Bringing Cassandra to Kubernetes means having an automated open source distributed datastore that SREs appreciate. Kubernetes is a container orchestration platform that has become increasingly popular as it helps to enables multi-cloud deployment for applications. As Kubernetes becomes the de facto solution for container orchestration, more and more developers (and enterprises) want to run Apache Cassandra databases on Kubernetes.It's easy to get started—especially given the capabilities that Kubernetes' StatefulSets bring to the table. When applications run within a Kubernetes cluster, you'll need to access those services from outside the cluster. Configure Cassandra or DSE in Kubernetes with Cass Operator. Related Videos.
