serverless open source alternative to AWS Aurora Postgres
Neon - Serverless, Fault-Tolerant, Branchable Postgres
We designed our storage from the ground up as a fault tolerant scale-out system built for the cloud. It integrates with cloud object stores such as S3 to offload cold data for cost optimization. Our storage architecture ensures high availability, scale out, and unlimited capacity that we call "bottomless".
