## AI overview

This article explains how Neon separates database storage from compute to provide elasticity and serverless scaling without sacrificing PostgreSQL performance. It describes the Local File Cache (LFC), an NVMe-backed caching layer that reduces the latency caused by network access to remote storage and can match the performance of PostgreSQL running on local NVMe disks when it covers the database working set.

## Source excerpt

Modern OLTP database systems such as Neon and AWS Aurora separate storage and compute. The main benefits of this architecture are elasticity and being "serverless". Storage appears "bottomless" and compute scales up and down with the load. A user doesn't need to commit to a certa...
