CLOUD STORAGE IN CLOUD COMPUTING

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 Scalability2) 99.999% Reliability3) High Performance4) Specifiable Configurability

Low Cost.

IntroductionWith 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 Storage System Architecture

Cloud Storage Reference ModelStorage 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.

This interface is also used by Administrative AppsManagement 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.

Advantages1. 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 Effectiveness3. Lower Impact Outages and Upgrades4. Disaster Preparedness

Disaster Recovery.

5. Simplified Planning. Flexible and provide storage as needed.

ConclusionCloud 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.
