Aiven vs Cassandra as a Service (DataStax Astra)

Aiven is a managed cloud data platform that deploys and operates popular open-source data technologies on major cloud providers. It simplifies database management, streaming, and caching for developers and enterprises. The platform handles routine administrative tasks such as automated backups, security patching, and scaling, allowing engineering teams to focus on building applications rather than managing infrastructure.
