At the Authorization Infrastructure event hosted by AuthZed, Andre, a software engineer at Turo, discussed how Turo addressed significant security and scalability challenges by implementing SpiceDB with managed hosting from AuthZed Dedicated. Turo, a leading car-sharing platform, transitioned from a rigid ownership-based permission model to a relationship-based authorization system, enabling fine-grained, team-based access control, which resolved issues of password sharing among fleet owners. The integration of SpiceDB proved advantageous by simplifying the design and implementation process while enhancing performance and throughput compared to traditional relational databases. The system's adaptability was highlighted by the ease with which new features, like support for inactive team members, were introduced with minimal code changes. AuthZed's managed hosting was praised for its reliability and cost-effectiveness, with only one incident in over two years of production use, allowing Turo to concentrate on business expansion without the burden of infrastructure management.
