Cloud computing is a technology that uses remote servers and the internet to maintain data and applications. This allows users to access files and applications from any device with an internet connection. Cloud computing provides efficient computing by centralizing storage, memory, processing and bandwidth. There are different types of cloud computing models including Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) as well as public, private, hybrid and community cloud types. The document discusses the advantages of cloud computing such as reliability, scalability, and reduced maintenance, as well as disadvantages around security, dependency, and cost.

- 1. Cloud Computing…………... Arghya Datta Rittwik Ghorai Tanmoy Basak Arijit Tapadar
- 2. What Is Cloud Computing:- Technology that uses the internet and central remote servers to maintain data and applications. allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth.
- 4. Characteristics:- Autonomic computing Client–server model Grid computing Mainframe computer Utility computing Peer-to-peer
- 5. Classification of Cloud on the basis of service provided
- 6. Software as a service (SaaS) This is the most common form of cloud computing which we see in action. It is a complete software offering on the cloud. They are accessed by the customers on pay per use basis. Example:- Gmail , Hotmail etc
- 7. Platform as a service (PaaS) The consumer creates the software using tools and libraries from the provider. The consumer also controls software deployment and configuration settings. The provider provides the networks, servers and storage . Example:- Wavemaker,Longjump etc
- 8. Infrastructure as a service (IaaS) Hardware related services are provided using the principles of Cloud Computing. These include disk storage and virtual servers. Amazon EC2, Amazon S3, Rackspace Cloud Servers are some of the leading vendors.
- 9. Cloud Computing classified basis of location Public Cloud Private Cloud Hybrid Cloud Community Cloud
- 10. Public Cloud Computing infrastructure is hosted at the vendor’s premises. The customer has no visibility over the location of the cloud computing infrastructure. The computing infrastructure is shared between organizations.
- 11. Private Cloud Computing architectu re is dedicated to the customer and is not shared with other organisations.Private clouds may be externally hosted ones as well as in premise hosted clouds.
- 12. Hybrid Cloud Organisations host some critical, secure applications in private clouds. The not so critical applications are hosted in the public cloud. The combination is known as Hybrid Cloud.
- 13. Community Cloud The cloud infrastructure i s shared between the organizations of the same community.
- 15. Advantages:- Reliability Scalability Performance Security Maintenance Virtualization Multi-tenancy
- 16. Disadvantages:- Security & Privacy Dependency (loss of control) Cost Decreased flexibility Knowledge And Integration
