While you can run DataStax Enterprise (DSE) both on premises and in the cloud, DataStax Astra on Google Cloud Platform provides the ability create Cassandra databases in minutes, with reduced complexity, fewer operational concerns, and an approachable entry point for developing your applications. DataStax Astra on Google Cloud Platform is a true database as a service (DBaaS) offering that provides a simplified cluster management experience with flexible pricing.
Also, DSE includes Advanced Workloads (DSE Search, Analytics, and Graph), which are not available in DataStax Astra on Google Cloud Platform.
