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.
 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.

Cloud Storage System Architecture

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.

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.

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.

14. 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.
