Private cloud storage is the service, which offers scalable, billable storage capacity. It is easy to manage and it is also rapidly provisioned to users as a service that offer within the organization. Private cloud storage is applied and used popularly by organizations as an alternative or great option to existing methods of providing shared storage to business units. However, private cloud storage is not always defined clear. Sometimes, there is still confusion with pools of virtualized storage provisioned manually to users. Now, we will discuss about the way to establish an internal, or private, storage cloud, and products delivering a private cloud storage infrastructure.
There are some key parts making the cloud storage different from simply presenting and provisioning storage of a data center.
Scalability, or elasticity is the ability to scale the infrastructure up and down to fulfill customer demand. Obviously, downward elasticity is not a problem for most IT departments. With an internal cloud, it’s the internal consumer which benefits from scalability, not the IT department. The key issue will be scaling upward because it requires physically deploying hardware and it also integrates it into the existing storage networking infrastructure.
Management As NIST definition, the requirement cloud resources should be quickly provisioned and released with management or effort. Therefore, we can see that traditional storage management will not work for cloud environments.
Storage catalogue in a lot of organizations, the requests for storage are often processed on an individual. This is clear that it is not a scalable modus operandi and it is difficult to automate while publishing standards of performance and efficiency in a cloud environment.
One more effective approach is providing the customer with a variety of offerings from a storage catalogue. The goal of the storage catalogue is to make a standard customer requests to a degree which enables them to be automated through orchestration software.
The service catalogue is not supplied by a vendor. However it is written by the IT department for its environment. The service catalogue isn’t a product but simply a definition of the offerings presented to internal consumers. Then, the storage hardware and software delivers storage to specifications which are laid out in the catalogue.
A truly specified catalogue will provides one further benefit: abstraction. If the provided resources are in a cloud infrastructure, the underlying technology would be abstracted from the customer opinion. The customer would only be concerned with the levels of the storage resources meet the agreed service.
