Cloud Storage is a service that allows data to be stored on a third-party-managed offsite storage system and made available through an API for web services.
Storage devices are commonly categorised into two categories:
Block Storage Devices
Clients are provided raw storage via the block storage units. To build volumes, these raw storage tanks are partitioned.
File Storage Devices
The Computing Systems file offers clients storage in the form of files, having their own file structure. This data is in Network Attached Storage ( NAS) form.
Cloud storage is generally classifiable into two categories:
Unmanaged Cloud Storage
Unmanaged cloud storage means the user can have the data preconfigured. The user can not format, instal his own file system or change the drive properties.
Managed Cloud Storage
Managed cloud computing provides on-demand on-line storage space. The cloud computing system, which is managed, tends to be a raw file that the user can partition and format.
The cloud storage system maintains multiple copies of data at multiple locations, on multiple computers. If one method fails, then changing the pointer to the location where the object is located is just needed.
The cloud provider can use Storage virtualization software such as StorageGRID to aggregate the storage assets into cloud storage systems. It provides a layer of virtualization that fetches data from multiple data systems into a single management structure. It can also handle the data over the Internet from CIFS and NFS file systems.
The virtual storage containers offer cloud computing services with high capacity. Logical Unit Number (LUN) of device , files, and other objects is generated in containers for virtual storage.
It is not the easy job to hold the information in cloud. Besides its flexibility and ease, the companies often face several challenges. Customers must be in a position to:
