Should I Use Aiven?
Aiven is an AI-ready open source data platform that combines open-source services to rapidly stream, store and serve data across major cloud providers — simply and securely.
Depends
DependsBuy it if you run serious multi-service data infrastructure — Kafka plus databases across clouds — and want it managed.
Solid managed open-source data platform for serious data teams; overkill for one simple database.
