Various vendors are providing cloud is a composition of two or more clouds (private, services using different cloud platforms.

It provides the benefits of various informative about existing cloud platform and discusses about deployment models [1].

  • Platform As a Service: Empowering Digital Transformation
    WHITE PAPER Platform as a Service: Empowering Digital Transformation Sponsored by: Oracle Robert P. Mahowald Larry Carvalho January 2015 EXECUTIVE SUMMARY Traditional business models are increasingly being disrupted by newcomers providing customers with a multichannel digital experience. IDC predicts that integration, consolidation, and rationalization in marketing technology will make up an average of 35% of total marketing technology budgets by 2015.1 With the rapid growth of mobile devices, speed to market is important for businesses competing for customers with dynamically changing needs. The ability to quickly change internal processes to match dynamic environments can be a differentiating factor for successful businesses. The platform-as-a- service (PaaS) market is flourishing because it helps businesses accelerate adaptation and innovation. PaaS offerings are helping IT departments with cloud and mobile enablement of their new and legacy applications while accelerating the delivery and scalability of those applications. While cloud technology that enables PaaS is fluid and changing rapidly, Oracle, with its public and private cloud solutions, is building a competitive position in the market by offering: . A broad range of services varying from raw compute and storage to mobile, Big Data, process, and document management to enable assembly of custom applications with a wide range of capabilities . Deployment choices and portability between public and private environments . Oracle database software, Java, and associated standards that give Oracle a PaaS technology with a foundation and components that have wide awareness and acceptance among enterprises . A single platform for mobile, on-premise, and cloud applications that makes it easier to build and maintain business solutions using a comprehensive and unified set of integrated components .

  • Oracle Corporation
    ORACLE CORPORATION The Oracle Corporation is an American global computer technology corporation, headquartered in Redwood City, California. The company primarily specializes in developing and marketing computer hardware systems and enterprise software products – particularly its own brands of database management systems. In 2011 Oracle was the second- largest software maker by revenue, after Microsoft.[3] The company also develops and builds tools for database development and systems of middle-tier software, enterprise resource planning (ERP) software, customer relationship management (CRM) software and supply chain management (SCM) software. Larry Ellison, a co-founder of Oracle, served as Oracle's CEO from founding. On September 18, 2014, it was announced that he would be stepping down (with Mark Hurd and Safra Catz to become CEOs). Ellison became executive chairman and CTO.[4] He also served as the Chairman of the Board until his replacement by Jeffrey O. Henley in 2004. On August 22, 2008, the Associated Press ranked Ellison as the top-paid chief executive in the world.[5] Larry Ellison , Ellison was born in New York City but grew up in Chicago. He studied at the University of Illinois at Urbana–Champaign and the University of Chicago without graduating before moving to California in 1966. While working at Ampex in the early 1970s, he became influenced by Edgar F. Codd's research on relational database design, which led in 1977 to the formation of what became Oracle. Oracle became a successful database vendor to mid- and low- Larry Ellison in October 2009. range systems, competing with Sybase and Microsoft SQL Server, Born August 17, 1944 (age 71) which led to Ellison being listed by Forbes Lower East Side, Manhattan, New York, U.S.

  • An Insider's Guide to SAS/ACCESS Software on SAS 9.4 M5 in the Cloud
    Paper SAS1838-2018 An Insider’s Guide to SAS/ACCESS Software on SAS 9.4M5 in the Cloud Jeff Bailey, SAS Institute Inc., Cary, NC ABSTRACT You might not have data in the cloud today, but chances are you will in the very near future. Are you ready? Do you have any idea where to start? If "no" is the answer to either of these questions, then this presentation is just what you are looking for. We answer the following questions (and more): • What are the steps involved in creating a database in a cloud environment? • What is Database as a Service (DBaaS)? • How does SAS® define the terms "cloud variant" and "database variant"? • How do I determine whether my cloud database is supported by SAS? The presentation would not be complete without discussing the major cloud players. We discuss Amazon Web Services (AWS), Microsoft Azure Cloud, Oracle Cloud, Teradata IntelliCloud, and Google Cloud Platform. INTRODUCTION 43,000! That was the attendance number being discussed at Amazon AWS re:invent in 2017. To put this into perspective, the town I grew-up in had a population of approximately 18,000. Granted, that was years ago, but the attendance number still amazes me. Another amazing fact is that in 2016 the conference drew approximately 30,000 people. The takeaway is that cloud computing is here to stay. Moving to the cloud is inevitable, like the sunrise. Over the course of the last year, I have personally heard the following comments from SAS customers: • “We do not want to move to the cloud, but we must if we want to remain competitive.” • “Companies are not moving to the cloud to save money.

Technology transitions require innovative models to fly, expand and scale, to accelerate migrations and changes. Cloud is all about a complete new way of accessing, consuming and developing technologies. It is about outputs and impacts more than features, wrapped in a new financial model. Such a disruption only happens every 10 years or so and it’s driving a secular growth opportunity for all of us. In order to be successful and thrive in this new way of doing business, we need to start with people; it always starts with and through people. We all need to educate ourselves and get access to relevant content sooner. We need to learn from what is working and accept it as the new order, the new continent. Jean-Marc Gottero To facilitate this very essential step of getting ourselves in the new model, we saw the need of a reference document that will aggregate and consolidate in EMEA A&C Vice President one place everything you need and want to know about the Cloud with Oracle. This is our Cloud guide, our Cloud bible. It is now ready and available; we Cloud are taking a commitment to keep updating it so it stays as the ultimate place for Cloud education. I cannot emphasize how this is a must-have for all of us to invest the time into getting Cloud ready and to dramatically expand our relevancy in the current and future market. It all starts here.
