About
Oracle Corporation is one of the world's largest enterprise software and cloud infrastructure companies, producing database software (Oracle Database, MySQL), cloud applications (Oracle Fusion ERP, HCM, SCM, CX), cloud infrastructure (OCI - Oracle Cloud Infrastructure), and industry-specific cloud solutions for healthcare (Cerner), retail, utilities, and financial services. Listed on NYSE (NYSE: ORCL) and headquartered in Austin, Texas (moved from Redwood City in 2020), Oracle generates approximately $55 billion in annual revenue and is led by co-founder Larry Ellison (who serves as Chairman and CTO) and CEO Safra Catz.\n\nOracle's business spans several large segments: Cloud Services and License Support (Oracle Cloud applications and database subscriptions — the largest and highest-margin segment), Cloud License and On-Premise License (new software licenses), and Hardware (Oracle Engineered Systems including Exadata database machines). The Oracle Database is the world's most widely used enterprise relational database, installed in virtually every major corporation globally. Oracle Fusion Cloud is the company's SaaS ERP, HCM, and CRM suite competing with SAP and Workday for enterprise cloud adoption.\n\nIn 2025, Oracle is experiencing significant growth from its OCI cloud infrastructure business — the company has built extensive GPU capacity for AI training workloads and signed large AI cloud contracts (including a massive contract with xAI for Grok model training). Oracle's strategic partnership with Microsoft Azure (Oracle databases available natively in Azure data centers) and its National Security Cloud (dedicated cloud for US government) have created new growth vectors. Oracle competes with SAP, Workday, and Salesforce for enterprise applications, and with AWS, Azure, and Google Cloud for cloud infrastructure.
