  2. 2. Cloud computing • What is Cloud computing? • What is the impact? • What are the benefits? • What are the enablers? • Cloud here to stay some examples
  3. 3. Cloud Computing New? Grid computing Utillity Computing Cloud Computing Addaptive Software As A Enterprise Service Platform As A On Demand Service Infrastructure as a service
  4. 4. Definition cloud computing 1. There is not one definition of cloud computing. 2. Every one can use the name.
  5. 5. Definition cloud computing Wikipedia Cloud computing is Internet (quot;cloudquot;) based development and use of computer technology (quot;computingquot;).It is a style of computing in which dynamically scalable and often virtualised resources are provided as a service over the Internet.Users need not have knowledge of, expertise in, or control over the technology infrastructure quot;in the cloudquot; that supports them The concept incorporates infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) as well as Web 2.0 and other recent (ca. 2007–2009) technology trends which have the common theme of reliance on the Internet for satisfying the computing needs of the users. Examples of SaaS vendors include and Google Apps which provide common business applications online that are accessed from a web browser, while the software and data are stored on the servers. The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams, and is an abstraction for the complex infrastructure it conceals
  6. 6. Definition cloud computing Marketspace Cloud Computing represents a new way to deploy computing technology to give users the ability to access, work on, share it and store information using the Internet. The cloud itself is a network of data centers - each composed of many thousands of computers working together - that perform the functions of software on a personal or business computer by providing users access to powerful applications, platforms and services delivered over the Internet.
  7. 7. What made it possible? Kryders Law Moore’s Law Computor memory Every 18 months doubles every 12 processing power months as function of doubles the price Now right time for cloud computing Grove’s Law Worlds global communication networks double every 100 years
  8. 8. Evolution of cloud computing Mainframe Mini computer Workstation PC Netbooks Smart phones Game consoles Cloud
  9. 9. Everybody is using the cloud • 1.5 miljard mensen verbonden met de cloud.
  10. 10. Variants of the Clouds • Companies host applications in the cloud that many users User Level access through Internet Connections. The service being sold or offered is a complete end-user application. “software as a service” Developer • Developers can design, build and test applications that run on the Cloud provieder’s infrastructure and then deliver those Level applications to end-users from the provider’s servers “platform as a service” • System administrators optain general processing, storage, IT Level database, management and other resources and applications through the network and pay only for what gets used. “Infrastructure as a service”
  11. 11. Not one Cloud?
  12. 12. Benefits and opportunities in the cloud 1. Anywhere/any time 2. Specization and customization of applications build in cloud 3. Collaboration 4. Cost advantages 5. CO2 reduction 6. Cloud-enabled storage as a universal service 7. Cloud-enabled processing power on demand
  13. 13. Advantage of clouds
  14. 14. Normal Respons
  15. 15. Cloud response Cloud E.g. Amazone - Essent
  16. 16. Cloud Enablers • Vitualization • Full connectivity • Open access • Reliability • Interoperability and user choice • Security • Privacy • Economic Value • Sustainability
  17. 17. Full connectivity 2/3 off all Google Searches in Asia are through mobile devices 87 off all Google Searches in Africa are through mobile devices
  18. 18. Reliability
  19. 19. Security 1. Virus 2. Identity fraud 3. Patches 4. Expertise 5. Cyber-crime laws 6. Security breach / selling company
  20. 20. Privacy 1. Location where data stored 2. Location where you live in 3. Mission critical information 4. Routing of Internet 5. Audits/ data protection standards 6. Deleting information
  21. 21. Sustainability Google Data centers Power comsumtion of use 19% extra cooling datacenters is doubled energy compared to in 2006 from 2000 and the average of 96% will be four-fold in 2020. World wide CO2 usage of data centers overtakes that of the aviation industry.
