Neon: How we made PostgreSQL serverless | POSETTE: An Event for Postgres 2025

From the creator

Video of a conference talk looking in detail at how Neon offers PostgreSQL as a serverless cloud service, which can automatically scale depending on the workload, and can scale all the way down to zero when it’s not used. This makes Neon a good fit for modern stateless applications. A database is very stateful by its nature, and PostgreSQL is a mature piece of server software. Creating the serverless illusion is not trivial. I will walk through some of the challenges and solutions in bridging that gap: • Start up in less than 1 s • Separating compute and storage • Running PostgreSQL in a microVM in Kubernetes • Connection management and pooling Heikki Linnakangas is a cofounder of Neon and a long-time PostgreSQL developer and committer. Since 2023, he has also been contributing to pgvector. ► Video bookmarks: ⏩ 00:00 Introduction to Serverless Postgres ⏩ 01:08 What does it mean for a service to be serverless ⏩ 04:03 Characteristics of serverless ⏩ 07:08 Serverless PostgreSQL ⏩ 09:29 Neon Architecture – diagram ⏩ 11:57 Separation of compute and storage ⏩ 13:06 Neon storage system - diagram ⏩ 15:42 Autoscaling compute ⏩ 23:24 Connection management ⏩ 25:33 Conclusion and resources Resources: https://neon.tech/ https://github.com/neondatabase/neon/pol 📕 Everything you need to know about POSETTE: An Event for Postgres 2025 can be found at: https://posetteconf.com ✅ Learn more: Watch more POSETTE talks: https://aka.m
