2. Why Cloud Computing ?
 Cloud Computing platforms provides easy access to
a company’s high-performance computing and
storage infrastructure through web services.
 Cloud Computing platforms provides:
1) Massive Scalability
2) 99.999% Reliability
3) High Performance
4) Specifiable Configurability
 Low Cost.

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 isn’t.
 The user’s 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.

10. 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.

11.  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.

13. 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.

15. Conclusion
 Cloud Storage with a great deal of promise, aren’t
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.
