2 Business drivers: Datacenter modernization IT organizations are updating IT infrastructure, creating dynamic computing environments to optimize server and storage economics, and improving IT service agility. Virtualization and cloud computing Use virtualization to create a dynamic, services-based infrastructure to support legacy migration projects and big data programs. The worldwide economic downturn has forced many businesses to contain expenses and improve operational efficiency. Many organizations are instituting cloud computing and virtualization initiatives to enhance business agility and to curtail capital equipment and operating expenditures. By consolidating workloads and virtualizing resources, businesses can reduce operational costs, while creating a more dynamic, services-based infrastructure to support IT initiatives such as legacy UNIX and RISC migration projects, and big data and analytics programs. Legacy UNIX and RISC migration Many organizations operate mixed IT environments, using Windows platforms for office productivity applications, Linux systems for web and IT infrastructure (DNS, file and print services, etc.), and UNIX platforms for line-of-business applications. As UNIX and RISC systems approach end of life, many enterprises are migrating legacy workloads to standards-based Linux platforms to reduce cost, enhance performance, and improve scalability. Big data and analytics Enterprises are kicking off big data projects to gain better insight into their customers and businesses. Collecting and analyzing massive volumes of unstructured data blogs, , social networking, and multimedia content helps organizations gain a deeper understanding of the marketplace. Many businesses are choosing Linux for high-performance computing initiatives and next-generation non-relational database implementations (Mongo, Couch, Hadoop, etc.) in order to enable high scalability and performance. Linux is emerging as the platform of choice for the extract, transform, and load (ETL) phases in data warehousing, business intelligence, and analytics. Red Hat Enterprise Linux satisfies key business requirements The world s leading open source Linux distribution meets demanding performance and reliability requirements at a significantly lower cost than proprietary operating systems.
