This architecture diagram shows the high-level relationship between regions in a hub and spoke variation of a decentralized data platform architecture. A central hub region provides a hub version of Oracle Autonomous Data Warehouse which reads shared data from the spoke regions. Each spoke region provides and instance of Autonomous Data Warehouse and versioned shares. Four spoke regions are shown: Europe, Middle East, Asia (EMEA), Latin America (LATAM), North America, and Japan, Asia-Pacific (JAPAC).
