Cloud Computing Data Storage
Cloud Storage is a service that allows to save data on offsite storage system managed by third-party and is made accessible by aweb services API.
Storage Devices
Storage devices can be broadly classified into two categories:
- Block Storage Devices
- File Storage Devices
Block Storage Devices
The block storage devicesoffer raw storage to the clients. These raw storage are partitioned to create volumes.
File Storage Devices
The file Storage Devices offer storage to clients in the form of files, maintaining its own file system. This storage is in the form of Network Attached Storage (NAS).
Cloud Storage Classes
Cloud storage can be broadly classified into two categories:
- Unmanaged Cloud Storage
- Managed Cloud Storage
Unmanaged Cloud Storage
Unmanaged cloud storage means the storage is preconfigured for the customer. The customer can neither format, nor install his own file system or change drive properties.
Managed Cloud Storage
Managed cloud storage offers online storage space on-demand. The managed cloud storage system appears to the user to be a raw disk that the user can partition and format.
Creating Cloud Storage System
The cloud storage system stores multiple copies of data on multiple servers, at multiple locations. If one system fails, then it is required only to change the pointer to the location, where the object is stored.
To aggregate the storage assets into cloud storage systems, the cloud provider can use storage virtualization software known asStorageGRID. It creates a virtualization layer that fetches storage from different storage devices into a single management system. It can also manage data fromCIFSandNFSfile systems over the Internet. The following diagram shows how StorageGRID virtualizes the storage into storage clouds:
Virtual Storage Containers
The virtual storagecontainers offer high performance cloud storage systems.Logical Unit Number (LUN) of device, files and other objects are created in virtual storage containers. Following diagram shows a virtual storage container, defining a cloud storage domain:
Challenges
Storing the data in cloud is not that simple task. Apart from its flexibility and convenience, it also has several challenges faced by the customers. The customers must be able to:
Get provision for additional storage on-demand.
Know and restrict the physical location of the stored data.
Verify how data was erased.
Have access to a documented process for disposing of data storage hardware.
Have administrator access control over data.
