  1. Cloud Computing Kwangyun Cho http://www.youtube.com/watch?v=8AXk25TUSRQ

  2. What is Cloud Computing? • The national survey was conducted in August 2012 by Wakefield Research • Survey question – ‘What is Cloud Computing?’ was asked to 1,000 American adults. • Survey result showed that 51% of the Americans are confused by the term “cloud”.

  3. What is Cloud Computing Cont’d • It is a Internet-based computing with shared resources, software, and information are provided to computers and other devices on demand.

  4. Users simply rent or access the software • Paying only for what they use.

  5. Traditional License Software (Benz) vs. Cloud Computing (Taxi)

  6. ‘Cloud’ • “Cloud” is simply a metaphor for the Internet. • People don’t care what is in the ‘cloud’ but they depend on reliably sending data (rain) to and receiving data from it.

  7. Key Characteristics • Data stored on the cloud (Internet) • Software and services available on the cloud • Broad network access.

  8. Cloud Computing Models • Cloud Software as a Service (SaaS): The vendor supplies the hardware infrastructure, the software product and interacts with the user through a front-end portal. Services can be anything from Web-based email to inventory control and database processing. • Example: Google Docs, Gmail, etc

  9. Cloud Computing Models • Cloud Platform as a Service (PaaS): A set of software and product development tools hosted on the provider’s infrastructure. Developers create applications on the provider’s platform over the Internet. • Example: Windows Azure

  10. Cloud Computing Models • Cloud Infrastructure as Service(IaaS): Delivers computer infrastructure as a service. Rather than purchasing servers, software, data center space or network equipment.

  11. Cloud Computing Models • Cloud Hardware as a Service(HaaS): • Hardware as a Service (Haas), in a grid-computing context, is a pay-as-you-go model for accessing a provider's infrastructure and CPU power. • Example: Amazon’s Elastic Compute Cloud

  12. 4 Types of Clouds • Public Cloud: The services are delivered to the client via the Internet from a third party service provider.

  13. 4 Types of Clouds • Private Cloud: These services are managed and provided within the organization. There are less restriction on network bandwidth, fewer security exposures and other legal requirements compared to the public Cloud.

  14. 4 Types of Clouds • Organization having similar requirement. • Concerns related to privacy, security and policy compliance

  15. 4 Types of Clouds Hybrid Cloud: Multiple internal and external providers

  16. 5 Layers of Cloud Computing

  17. Client: A cloud client consists of computer hardware and computer software which relies on the cloud for application delivery. • Application: Runs over Internet, no need to install and maintain, complete customizable applications • Platform: A cloud platform such as platform as a service, the delivery of a computing platform and for solution stack as a service, facilitates deployment of application.

  18. Infrastructure: Network of servers, Cloud infrastructure such as infrastructure as a service is the delivery of computer infrastructure typically a platform virtualization environment as a service. • Server: Consists of computer hardware and software products that are specifically designed for the delivery of cloud services.

  19. Cloud Providers

  20. Google

  21. Microsoft • Azure: • Internet-scale cloud computing and services platform hosted in Microsoft data Centers. • Provides a range of functionality to build applications that span from consumer web to enterprise scenarios.

  22. Pros and Cons

  23. Pros

  24. Cons

  25. The Future of Cloud Computing

  26. The Future of Cloud Computing • For now, companies don’t fully trust Cloud Computing and only uses it for small projects. • Details such as licensing, privacy, security, compliance and network monitoring need to be finalized for the trust to be realized. • A single hard drive for the rest of a person’s life, accessible anywhere with internet.

  27. Time’s Up!
