  2. 2. Introduction
  3. 3. What is Cloud Computing? “Cloud computing is Web-based processing, whereby shared resources, software, and information are provided to computers and other devices (such as smartphones) on demand over the Internet ”
  4. 4. What is Cloud Computing?
  5. 5. Characteristics of Cloud Computing
  6. 6. Essential characteristics of Cloud Computing Cloud Computing On-demand self-service Ubiquitous network access Resource pooling Rapid elasticity Flexible pricing - Pay per use
  7. 7. Characteristics of Cloud Computing  On-demand self-service • A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider.
  8. 8. Characteristics of Cloud Computing  Ubiquitous network access • Cloud computing is a model for enabling ubiquitous, convenient, on- demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction
  9. 9. Common Characteristics of Cloud Computing  Resource pooling • Resource pooling is an IT term used in cloud computing environments to describe a situation in which providers serve multiple clients, customers or "tenants" with provisional and scalable services.
  10. 10. Common Characteristics of Cloud Computing  Rapid Elasticity • Capabilities can be expanded or released automatically (i.e., more CPU power, or ability to handle additional users). • To the customer this appears seamless, limitless, and responsive to their changing requirements.
  11. 11. Common Characteristics of Cloud Computing  Flexible Pricing - Pay per use • pay as much as used and needed
  12. 12. Advantages of Cloud Computing
  13. 13. Advantages of Cloud Computing • Lower Computing Cost • Improved Performance • Reduced Software Cost • Instant Software Updates • Unlimited Storage Capacity • Increased Data Reliability • Device Independence and the “always on!, anywhere and any place” • Free From Maintenance and the “no-need-to-know”
  14. 14. Cloud Service Models
  15. 15. Cloud Service Layers
  16. 16. Cloud Service Models - Definitions • SaaS is a software delivery methodology that provides licensed multi-tenant access to software and its functions remotely as a Web-based service. Software as a Service (SaaS) • PaaS provides all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely from the Internet. Platform as a Service (PaaS) • IaaS is the delivery of technology infrastructure as an on demand scalable service. Infrastructure as a Service (IaaS)
  17. 17. Cloud Service Models - Characteristics • Scalable; Multi-tenant; Metadata driven configurability • Sometimes free; easy to use; good consumer adoption; proven business models Software as a Service (SaaS) • Highly scalable; multi-tier architecture; Multi tenant environments • Developers can upload a configured applications and it “runs” within the platform’s framework Platform as a Service (PaaS) • Offers full control of a company’s infrastructure; not confined to applications or restrictive instances • Sometimes comes with a price premium; can be complex to build, manage and maintain Infrastructure as a Service (IaaS)

  19. 19. Cloud Service Models - Examples Software as a Service (SaaS) Platform as a Service (PaaS) Infrastructure as a Service (IaaS)
  20. 20. Cloud Implementation Types
  21. 21. Cloud Implementation Types
  22. 22. Public Cloud • Owned and managed by service provider • Made available to the general public or a large industry group
  23. 23. Private Cloud • Operated solely for an organization • May be managed by the organization or a third party • Limits access to enterprise and partner network • Retains high degree of control, privacy and security
  24. 24. Hybrid Cloud • Composition of two or more clouds (private, public) bound together by standardized or proprietary technology that enables data and application portability
  25. 25. • Amazon Web Services (AWS) is a secure cloud services platform, offering compute power, database storage, content delivery and other functionality to help businesses scale and grow. Explore how millions of customers are currently leveraging AWS cloud products and solutions to build sophisticated applications with increased flexibility, scalability and reliability.
  26. 26. Conclusion • Cloud Computing is the fastest growing part of network based computing . It Provides tremendous benefits to customers of all sizes: simple users, developers, enterprises and all types of organizations.
