What is cloud computing?
  • 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.
  • - NIST Definition

3
Characteristics
  • On-demand self-service
  • Broad network access
  • Resource pooling
  • Rapid elasticity
  • Measured service

4
Service Models
  • Software as a Service (SaaS)
  • Platform as a Service (PaaS)
  • Infrastructure as a Service (IaaS)

5
Software as a Service (SaaS)
  • Gives the user the ability to utilize
    applications hosted on a cloud infrastructure
  • Borrowing/renting software online
  • Google Documents

6
Platform as a Service (PaaS)
  • The user is able to deploy custom applications
    and services
  • User has control over deployed applications
  • Similar to an app store

7
Infrastructure as a Service (IaaS)
  • Technology from a cloud provider is outsourced to
    a user/client as a service
  • User has control over operating systems, storage,
    and deployed applications
  • Pay per use basis

Deployment Models
  • Private Cloud
  • - Single organization
  • Community Cloud
  • - Multiple organizations
  • Public Cloud
  • - General public
  • Hybrid Cloud
  • - Multiple cloud infrastructures
  • - (ex. private cloud oublic cloud)
