Introduction Much like Oracle’s customer base (some 400,000 companies in 145 countries), Oracle deploys Oracle database, middleware, and application products to support its day-to-day business operations. Oracle IT departments are chartered to provision and manage continuously available enterprise applications critical to running its business. These applications deliver strategic functionality across all facets of the company—from product development to financials to support for production, sales, and service operations, allowing more than 120,000 Oracle employees to be productive each and every day. By virtualizing enterprise applications using Oracle VM, Oracle’s IT organizations realize greater flexibility and lower infrastructure costs. Instead of implementing physical machines for each required operating system version and application release, virtualization using Oracle VM consolidates servers and provides efficiencies that help to decrease capital (CAPEX) and operating expenses (OPEX). At the same time Oracle VM helps IT deploy services more rapidly, allowing administrators to provision new applications quickly to meet emerging requirements and shifts in application demand. Oracle relies on Oracle VM as its premier virtualization technology—and not just because Oracle VM is Oracle’s own virtualization software. Based on proven Xen hypervisor technology, Oracle VM offers reliability and scalability for enterprise applications—Oracle Database, Oracle Fusion Middleware, and Oracle applications: Oracle E-Business Suite and Oracle’s PeopleSoft, JD Edwards EnterpriseOne, and Siebel Customer Relationship Management (Siebel CRM). Oracle software teams aggressively test and fully integrate these applications with Oracle VM. That’s why Oracle IT managers know that virtualization on Oracle VM delivers the performance and high service levels needed to meet exacting business requirements. Complementary technologies such as Oracle VM Templates accelerate application provisioning, allowing administrators to stand up complete Oracle application stacks reliably and repeatedly, reducing deployment risk and speeding time-to-use. This paper highlights Oracle IT environments—notably Oracle Product Development IT and Oracle Managed Cloud Services—that rely on Oracle VM to deliver highly reliable Oracle enterprise applications. It discusses the advantages that these IT organizations achieve by virtualizing workloads on Oracle VM, especially for Oracle Database and Oracle software applications that demand continuous availability, scalable performance, and easy manageability. The paper also discusses how several Oracle engineered systems incorporate Oracle VM. Tight integration in these systems enhances the overall stability and scalability of Oracle application workloads on Oracle VM, both for deployments on engineered systems as well as on general-purpose servers.
