Neon is an open-source alternative to AWS Aurora PostgreSQL. Cloud-native analytical databases have embraced the technique of separating storage from compute nodes to elastically scale on demand. However, it's difficult to do the same in a transactional database. Neon achieves this with its new multi-tenant storage engine for PostgreSQL. With minimal changes to the mainstream PostgreSQL code, Neon leverages AWS S3 for long-term data storage and elastically scales the processing up or down (including scale-to-zero) for compute. This architecture has several benefits — including cheap and fast clones, copy-on-write and branching. We're quite excited to see new innovations on top of PostgreSQL. Our teams are evaluating Neon, and we recommend you assess it as well.
