How Neon's lakebase architecture stays resilient to cloud failures

Neon's lakebase architecture is engineered to maintain resilience against cloud failures, addressing the challenges posed by the increased demands of agent-driven workloads. This architecture leverages a stateless Postgres compute model, separating compute and storage to enhance availability without requiring costly hot standbys or long recovery times. Neon's approach includes a high availability design that utilizes zone-redundant storage and a unique control plane that functions as a data plane for critical operations, ensuring reliability in database startups and management. The platform employs a cell-based architecture to limit the impact of failures, allowing for scalable regional growth while containing potential disruptions. A rigorous testing regime involving failure simulation and injection ensures robust system reliability, with the goal of maintaining high availability standards for all databases. Continuous measurement of service level indicators and objectives helps track and improve the system's performance, aiming for best-in-class reliability and user trust in Neon's database services.
