From Aurora to PlanetScale: Intercom’s Database Evolution with Brian Scanlan

Brian Scanlan, Senior Principal Engineer at Intercom, the company building Fin.ai, joins Corey Quinn on Screaming in the Cloud to discuss Intercom’s move from AWS Aurora to PlanetScale’s managed Vitess after years of scaling challenges with their Ruby on Rails monolith. He explains how 13 Aurora clusters created operational pain and why PlanetScale’s white-glove, partnership-driven model won out over Amazon’s building-block approach.

The discussion also covers Intercom’s volunteer-based on-call system, their pivot to AI agents after ChatGPT’s launch, concerns about the shrinking pipeline of systems engineers, and how companies like PlanetScale and Snowflake are outpacing AWS by delivering superior user experiences.

About Brian: Brian is an engineer based in Intercom’s Dublin office. He fixes problems, builds things, and grows people.
