Move Fast and Don't Break Things: Scaling Databases for the AI Era — PlanetScale
This talk outlines how modern infrastructure must scale to support the massive, unpredictable traffic generated by AI agents. The speaker argues that achieving high availability (three to five nines) requires adopting advanced architectural principles—including isolation, redundancy, sharding, back pressure, and decoupling. Crucially, the talk details how these complex systems can be safely managed and modified by AI agents through developer-friendly primitives like VSchema JSON files, Traffic Control budgets, and Git-like database branching.

Scaling for AI-Driven Traffic
2:02
The current era, powered by AI agents, demands infrastructure that can handle massive, unpredictable spikes in traffic, requiring a shift from traditional scaling methods.

The Importance of Developer Experience (DX)
Focusing on a robust developer experience (DX) for infrastructure—providing safe, controlled primitives—is the key to enabling AI agents to interact with and manage complex systems reliably.
