  • Cloud computing has the potential to create irreversible changes in how computers are used around the world, says David Carrera, director of the Cloud Computing (CC) research team at Spain’s Universitat Politecnica de Catalunya (UPC). Carrera says cloud computing technology’s objective is to move any applications stored on a computer to a remote location, eliminating all the standard components, including operating systems and hard drives, which are necessary in today’s computers and make them accessible online through a standard browser. Traditional computers will become obsolete, and instead of traveling with laptops, users will be able to rent a computer and access all of the information and programs online. Carrera says the ultimate goal of cloud computing is to mix and manage applications in an intelligent manner. For example, cloud computing could be used to create software that monitors the response of a machine or appliance in real time and controls its power supply, optimizing energy use and saving money, Carrera says. The CC team is researching systems for coordinating the thousands of terminals and nodes that compose the cloud, a major concern of technology companies. “By applying artificial intelligence to the cloud, we are hoping to develop a system through which computers can manage themselves,”

    1. 1. Subjects:<br /><ul><li>Introduction
    2. 2. Cloud Integration
    3. 3. Future</li></ul>On to the<br />Introduction<br />
    4. 4. Cloud computing is a pay-per-use model for enabling available, convenient, on-demand accessto a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. <br />Lots of definitions of Cloud Computing<br />
    5. 5. Definitions of Cloud Computing<br />Clouds are hardware-based services<br />offering compute, network and storage capacity where: <br />▪ Hardware management is highly abstracted from the buyer<br />▪ Buyers incur infrastructure costs as variable OPEX<br />▪ Infrastructure capacity is highly elastic (up or down)<br />
    6. 6. Quotes<br />“Cloud computing has the potential to create irreversible changes in how computers are used around the world”<br />“Cloud computing technology’s objective is to move any application stored on a computer to a remote location, eliminating all the standard components, including operating systems and hard drives, which are necessary in today’s computers and make them accessible online through a standard browser. “<br />

    34. 34. Decoupled:<br />1<br />SFA<br />HRM<br />KMS<br />Custom<br />Force<br />Sites<br /><br />Force<br />Sites<br />Force<br />Sites<br />2<br />3<br />SAP<br />SAP initiates import and export of data. Orders in are unresolved and new customers will be leads until a successful feedback of the backend is given.<br />This mechanism is called decoupled and requires not much changes on the current IT landscape.<br />Independent development of steps is possible:<br />Front-end User Interface (starting with leads)<br />Loading of customer data from your backend<br />Getting contracted updates and changes to your backend<br />
    35. 35. References Decoupled<br /> ( PAAS)<br /> (integration as a service)<br />
    36. 36. Decoupled<br /><ul><li>Can be implemented without backend where updates are managed manually
    37. 37. Strong separation of concern
    38. 38. Only keep parts highly available for the Internet and not for internal use (no costs)
