The public Cloud

The public cloud is a set of hardware, networking, storage, services, applications, and interfaces owned and operated by a third party for use by other companies or individuals. These commercial providers create a highly scalable data center that hides the details of the underlying infrastructure from the consumer.

Public clouds are viable because they typically manage relatively repetitive or straightforward workloads. For example, electronic mail is a very simple application. Therefore, a cloud provider can optimize the environment so that it is best suited to support a large number of customers, even if they save many messages.

The private cloud

A private cloud is a set of hardware, networking, storage, services, applications, and interfaces owned and operated by an organization for the use of its employees, partners, and customers. A private cloud can be created and managed by a third party for the exclusive use of one enterprise.

The hybrid cloud

A hybrid cloud is a combination of a private cloud combined with the use of public cloud services where one or several touch points exist between the environments. The goal is to combine services and data from a variety of cloud models to create a unified, automated, and well-managed computing environment.

CDMI – Cloud Data Management Interface 

The Cloud Data Management Interface defines the functional interface that applications will use to create, retrieve, update and delete data elements from the Cloud. As part of this interface the client will be able to discover the capabilities of the cloud storage offering and use this interface to manage containers and the data that is placed in them. In addition, metadata can be set on containers and their contained data elements through this interface.

This interface is also used by administrative and management applications to manage containers, accounts, security access and monitoring/billing information, even for storage that is accessible by other protocols. The capabilities of the underlying storage and data services are exposed so that clients can understand the offering.

Data Deduplication

[Storage System] The replacement of multiple copies of data—at
variable levels of granularity—with references to a shared copy
in order to save storage space and/or bandwidth.

IOPS (input/output operations per second) is the standard unit of measurement for the maximum number of reads and writes to non-contiguous storage locations. IOPS is pronounced EYE-OPS.

IOPs is often measured with an open source network testing tool called an Iometer. Measuring both IOPS and latency can help a network administrator predict how much load a network can handle without performance being negatively affected.

Storage Capacities:

Storage capacities and data transfer rates and amounts shall be reported in Base-10. IO transfer sizes and offsets shall be reported in Base-2. The associated units and abbreviations used in this specification are:

  • A kilobyte (KB) is equal to 1,000 (103) bytes.
  • A megabyte (MB) is equal to 1,000,000 (106) bytes.
  • A gigabyte (GB) is equal to 1,000,000,000 (109) bytes.
  • A terabyte (TB) is equal to 1,000,000,000,000 (1012) bytes.
  • A petabyte (PB) is equal to 1,000,000,000,000,000 (1015) bytes
  • A kibibyte (KiB) is equal to 210 bytes.
  • A mebibyte (MiB) is equal to 220 bytes.
  • A gibibyte (GiB) is equal to 230 bytes.
  • A tebibyte (TiB) is equal to 240 bytes.
  • A pebibyte (PiB) is equal to 250 bytes
