- 2. What is Cloud Computing? Types of Cloud Computing Layers of Cloud Computing Services Advantages & Disadvantages
- 3. …moving computing and data away from the desktop & the portable PC and simply displaying the result of computing that takes place in a centralized location and is then transmitted via internet to user’s screen. It offers the ability to access software or information that can be delivered on- demand , over the internet , without the need to store it locally.
- 4. Private Cloud Public Cloud Community Cloud Hybrid Cloud
- 5. Provide hosted services to a limited number of people. Reliable Secure Efficient Controlled Flexible
- 6. Service provider makes resources dynamically available Benefits: easy and in expensive setup scalability no wasted resources Ex: Amazon Elastic Computer cloud, IBM’s Blue Cloud, Sun Cloud, Google AppEngine.
- 7. Organizations having similar requirement Privacy, security, and policy compliance Ex.: Google’s “Gov Cloud”
- 8. Multiple internal and external providers Composition of more clouds Application: Archiving of backup functions. deploying a web application in the cloud.
- 9. The five layers: Client Application (SaaS) Platform (PaaS) Infrastructure (IaaS) Server Computer, Phones (browsers) Google apps, SalesForce CRM Google App Engine, Azure Nimbus, AWS Networks, Virtualization
- 10. Hardware & Software Essentially useless without cloud E.g.: Computers & phones.
- 11. Run over internet No need to installmaintain Complete, customizable application E.g.: Google Apps, SalesForce CRM.
- 12. Deployment without complexity Eliminate most management tasks Pre-built components E.g.: Google App Engine, Microsoft Azure.
- 13. Network of servers Virtualized Billed on utility ba E.g.: Nimbus, AWS.
- 14. Hardware Software Network of virtualized computer E.g.: better OS, multi- core processors
- 15. Processor speed becomes less important then internet connection speed. Netbooks become practical. Low maintenance. Privacy.
- 16. Physical location of hardware and software is unknown. Site inspections and audits are hard. Availability. Constant connectivity is required. Risk of data loss due to improper backups or system failure.
