Cassandra Total Cost of Ownership Study: Product Evaluation: Serverless Cassandra and Self-Managed OSS Cassandra: 3-year Total Cost of Ownership (TCO)
This study examines the full cost and true value of self-managed OSS Apache Cassandra® vs DataStax AstraDB fully managed DBaaS in Google Cloud. Our three-year total cost of ownership (TCO) calculations account for dedicated compute hardware (for self-managed Cassandra), cost per read and write operation (on Astra DB), storage growth (each write operation adds new data) and people cost. People costs consider that certain capabilities in Astra DB needed for the workload were not available in self-managed Cassandra, requiring workarounds. We used market rates and typical splits of full-time equivalent (FTE) and consulting to determine our people costs.
