Cloud computing provides computational resources on demand via a computer network. There are three main types of cloud services: SaaS where customers rent hosted software; PaaS where customers rent infrastructure and tools; and IaaS where customers rent fundamental computing resources like processing and storage. Cloud computing provides benefits like reduced investment, scalability, flexibility and efficiency compared to owning computing resources. However, issues around trust, privacy, security and regulations still need to be addressed for cloud computing's full potential to be realized.

- 3. What is Cloud Computing? provision of computational resources on demand via a computer network.
- 4. Type Of Services • Customers rent software hosted by the vendor. SaaS Software-as-a-Service • Customers rent infrastructure and programming tools hosted by the vendor. PaaS Platform-as-a-Service • Customers rent processing, storage, networking and other fundamental computing resources IaaS Infrastructure-as-a-Service
- 5. SaaS Software-as-a-Service It's all On Demand Rich Internet application web sites Office Productivity • E.g.: Flickr, Salesforce.com, Cisco WebEx office, Gmail, IBM
- 6. PaaS Virtual Development-platform-as-a-service Database App Servicer Reduce cost of buying & managing S/w & H/w Example : Google App Engine, Microsoft SQL Server Data Services, Engine Yard, Salesforce.com’s Force.com
- 7. IaaS • Backbone of Entire system • Physical storage space • Processing capabilities • Systems Management • E.g.: Akamai, Amazon EC2, CohesiveFT, Mosso, Joyent Accelerators
- 8. Utility Computing Platform as a Service (PaaS) Cloud-based User Applications
- 9. Cloud Benefits • Cloud = Less Investment (not own data center, hardware; use outside provider of servers, storage, and bandwidth) • Cloud = Scale (tens of thousands of server computers) • Cloud = Flexible and Efficiency
- 11. • Trust, Privacy and Availability • Performance, Ownership & Cost Savings • Creation and adoption of new software development processes and training • Security, Legal and Regulatory issues

- 13. • It is a platform for running windows application and storing their data in the cloud. It is mostly known as Windows Azure. • Nearly every application uses some platform, software on the machine it runs on. • There are two kinds of platforms. – 1) On-premises platform, – 2) Cloud Platform. What Azure Mean?
- 14. • It include various support function, such as standard library, storage and a base os. • On-Premises: One that will run within an organization. • Cloud : It allow developers to write application that running the cloud. • Azure supports both platform. What is Platform?
