How Postgres Powers 40 Percent of New Cloud Databases
The CTO Podcast with Fexingo · 2026-06-13 · 9 min
Episode notes
Lucas and Luna examine how PostgreSQL has quietly become the default database for modern cloud-native applications. They trace the journey from a 1996 open-source project to powering 40 percent of new database instances on AWS, Azure, and Google Cloud. The episode focuses on the architectural decisions that made Postgres scalable: its extension ecosystem, the rise of managed services like Aurora and Cloud SQL, and how its MVCC concurrency model handles mixed workloads. They also discuss why developers are migrating from proprietary databases and what Postgres's dominance means for the database industry. Specific examples include how Instacart uses Postgres for real-time inventory and how Citus extends it for sharding. #PostgreSQL #CloudDatabases #DatabaseArchitecture #OpenSource #AWS #AuroraPostgres #CloudSQL #MVCC #Citus #Instacart #DatabaseMigrations #ExtensionEcosystem #ManagedDatabases #BusinessTechnology #Business #TechLeadership #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
