Cloud Computing : Core Features and Three Models
- 3. Cloud computing is a model for managing, storing and processing data online via the internet. Manage Storage Process
- 4. Core features of cloud computing On demand service Shared resources Scalability and elasticity Broad Network Access
- 5. Three delivery model SAAS PAAS IAAS
- 6. SaaS – Software as a Service Third party application over Internet No physical connection
- 7. SaaS – Software as a Service • Universally accessible • Eliminates expenses • Vendor provides modest software tools Pros: • Portability and browser issue • Internet performance • Compliance restrictions Con's:
