Oracle is the world's largest enterprise database company, with its Oracle Database running the back-end of 98% of Fortune 500 companies. Its cloud pivot (Oracle Cloud Infrastructure) is winning hyperscale AI customers like xAI, Microsoft, and OpenAI. Oracle Fusion ERP and NetSuite serve 40,000+ organizations. 80%+ of global airline reservations run on Oracle.
Key relationships in depth
Oracle and Microsoft have a significant and unusual strategic partnership announced in 2019 and expanded in 2023, under which Oracle Database can run directly on Microsoft Azure through Oracle Database Service for Azure (ODSA), allowing customers to run Oracle workloads on Azure without migrating off Oracle. Azure and Oracle Cloud Infrastructure are also directly interconnected through Oracle Interconnect, enabling low-latency data transfers between OCI and Azure data centers in multiple global regions.
Why it matters: The Oracle-Microsoft partnership reflects a pragmatic recognition that Oracle's vast installed base of enterprise Database customers are also Azure customers, and forcing them to choose between Oracle Database and Azure cloud creates customer friction that benefits AWS and Google. By making Oracle Database a native Azure offering, both companies capture more enterprise cloud spending that would otherwise go to AWS or Google as customers modernize their Oracle-dependent applications.
Oracle Cloud Infrastructure has become one of NVIDIA's fastest-growing hyperscaler customers, purchasing $40B+ of NVIDIA GPUs to build out its Stargate data center network. Oracle's competitive pricing versus AWS, Azure, and GCP has attracted AI startups requiring dense GPU clusters at lower rates.
Why it matters: Oracle's belated but aggressive entry into AI cloud has been fueled almost entirely by NVIDIA supply. Stargate, the $500B joint AI infrastructure project involving OpenAI, Oracle, and SoftBank, placed Oracle at the center of AI infrastructure investment. NVIDIA GPUs are Stargate's core compute.
Oracle and Google Cloud launched Oracle Database@Google Cloud in 2024, a first-of-its-kind partnership that deploys Oracle Exadata and Autonomous Database hardware physically inside Google Cloud data centers, allowing enterprises to run Oracle workloads with sub-millisecond latency to Google Cloud services. At Google Cloud Next 2026, the companies expanded the partnership with Oracle AI Database Agent for Gemini Enterprise, enabling natural language queries across Oracle data using Google's Gemini models.
Why it matters: Thousands of enterprises run Oracle databases as their system of record but want to build new cloud applications on Google Cloud, and Oracle Database@Google Cloud eliminates the latency and data egress costs of connecting Oracle on-premises to GCP. Google gains Oracle's massive enterprise customer base as a GCP migration catalyst, and Oracle gains cloud distribution and a strategic alliance that validates OCI as a credible hyperscale alternative.
Oracle and Amazon are fierce competitors in cloud database and infrastructure markets, with AWS's RDS, Aurora, and DynamoDB database services competing directly with Oracle Database and Oracle Autonomous Database for enterprise workloads. Amazon also competes with Oracle through AWS's application migration tooling that specifically helps enterprises escape Oracle Database licensing costs by migrating to AWS-native databases. Despite the competition, many enterprises run Oracle Database on AWS infrastructure, making Amazon a paradoxical enabler of Oracle's database revenue.
Why it matters: Oracle's database licensing model, where customers pay license fees based on processor counts, generates an enormous annual recurring revenue stream from its installed base of enterprise customers. AWS has built explicit Oracle-to-AWS migration tools (AWS Database Migration Service, AWS Schema Conversion Tool) to help Oracle customers reduce Oracle licensing costs by moving to Aurora PostgreSQL, directly attacking Oracle's most profitable revenue stream.
