- 4. Introduction With Cloud storage, data is stored on multiple servers, rather than on the dedicated servers used in traditional networked data storage. Data is stored on virtual servers from the users point of view and seems like it has been stored to a particular place, but it isnt. The users data could be stored on any one or more of the computers used to create the cloud. The actual storage location may even differ from day to day or even minute to minute, as the cloud dynamically manages available storage space. Cloud computing refers to the delivery of computing services including servers, storage, databases, networking, software, and more over the internet. It offers flexible resources, cost savings, and scalability. This technology has revolutionized the way businesses operate and individuals access applications, data, and IT resources.

- 9. Cloud Storage Reference Model Storage to be provided on demand, drawn from a pool of resources. Client will be able to discover the capabilities of the cloud storage offering and use this model to manage containers and the data that is placed in them. Cloud Data Management Interface (CDMI) is the functional interface that applications will use to create, retrieve, update and delete data elements from the cloud. Ashish Gohel , 8th sem ISE
- 10. This interface is also used by Administrative Apps Management Apps to manage containers, accounts, security access and monitoring/billing information. The capabilities of the underlying storage and data services are exposed so that clients can understand the offering. Ashish Gohel , 8th sem ISE Continued

- 12. Advantages 1. Ease of Management The maintenance of the s/w, h/w and general infrastructure to support storage is drastically simplified in the cloud. 2. Cost Effectiveness 3. Lower Impact Outages and Upgrades 4. Disaster Preparedness Disaster Recovery. 5. Simplified Planning. Flexible and provide storage as needed. Ashish Gohel , 8th sem ISE
- 13. Challenges 1. Security 2. Data Integrity. 3. Computational Power. 4. Replication time . 5. Cost. 6. Reliability. Ashish Gohel , 8th sem ISE
- 14. Conclusion Cloud Storage with a great deal of promise, arent designed to be high performing file systems but rather extremely scalable, easy to manage storage systems. Thanks to Data Replication, which makes Storage approach in cloud more Scalable. Ashish Gohel , 8th sem ISE
