Cloud storage Big PK: Public cloud, private cloud and mixed cloud

Advantages of cloud storage technology

In terms of lower overall storage costs, the benefits of using the cloud storage technology are unacceptable to unstructured data. Cloud storage technology is a service based, without the need to purchase, manage and maintain storage hardware devices, depending on this service, even if not eliminated, can significantly reduce the cost of data center and storage management personnel. Cloud storage overcomes expensive technical updates, usually starting in the 3-5 years after the initial purchase, either with state-of-the-art technology or simply persuading the purchase of expensive old array support contracts.

Cloud storage technology configures a large amount of storage space by eliminating the expected growth capacity and load of traditional data storage to achieve a nearly 100% utilization of the data space. In addition to saving overall cost, the scalability of cloud storage, transparent support infrastructure and peak load are the most attractive features.

Public cloud storage

The public cloud storage service is one of the options for cloud storage, and its service providers are growing rapidly, including companies such as US telephone and telegraph companies, Amazon, Iron Mountain, Microsoft, Nirvani, Rackspace hosting providers, and many others. Their storage infrastructure typically includes a low-cost storage node that is directly attached to the drive and an object-based storage body responsible for managing the distribution of cross node content. Public cloud data is usually accessed via Internet protocol, mostly in the state of expression (REST), and rarely through Simple Object Access Protocol (SOAP). Resilience and redundancy are achieved by storing an object at least two nodes. Currently based on a monthly charge of $1 per 1 billion byte, depending on the service provider, there may be additional data transfer costs and access fees.

Public cloud storage is designed for a large number of tenants and provides each customer with data isolation, access, and security services. The content types of the public cloud storage range from static Non-core application data, required archived content to data backup, and catastrophic recovery data. Public cloud storage is not ideal for active content that has been changing. The main focus of the enterprise is on security and, to some extent, performance when using public cloud storage.

Internal or private cloud storage

Internal or private cloud storage runs on a dedicated infrastructure in the data center, so that the two main concerns of security and performance are fully met, and others provide the same benefits as public cloud storage. While larger enterprises may use multi-tenant devices to isolate multiple visits between departments or offices, the internal storage cloud is typically targeted at a single tenant. Unlike public cloud storage, the scalability of internal cloud storage is more common, so its products are more likely to have traditional storage hardware devices in the background. For example, HP's Cloudstart is the HP Blade System matrix (Bladesystemmatrix), an HP StorageWorks Enterprise Virtual Array (EVA) home array and cloud services Automation (CSA) Software integrates into the internal cloud storage infrastructure. HP Cloudstart itself is not a private cloud storage product because it lacks service-based key elements. Instead, it is a beneficial infrastructure that is used by HP, HP partners and even those that use it as a fully managed, instant-paid cloud storage product.

Hitachi Data System Private file layered cloud storage service is an example of a private cloud storage product. Using the Hitachi Content Platform (HCP), it resides in the customer's data center, but is owned and managed by Hitachi Corporation. In addition to the initial installation fee, the customer is paid with. Similarly, relying on this technology, Nirvanix's Hnode provides a fully managed, paid-for internal cloud product within the data center, which provides the impetus for a Nirvanix storage distribution network (SDN).

Mixed cloud storage

Users with a mixed cloud storage environment can manage internal and external resources. Because hybrid cloud scenarios typically provide a field device, they can also provide local cache and memory, duplicate data deletion, and encrypt it device data.

However, the hybrid cloud solution must meet certain key requirements to make the hybrid cloud storage work. They must act as almost transparent as the same type of storage, with the function of proper maintenance activities and the frequent use of data in the field, while moving inactive data to the cloud. These cloud types depend on the actual situation of the enterprise to determine when the specific data is moved to the cloud or when it exits from the cloud.

Each cloud storage option discussed here has its advantages and disadvantages. Public clouds are highly scalable, but often slow in performance. Private clouds are generally highly reliable, but with limited scalability. The hybrid cloud may be needed to provide some companies with the internal controls they seek, but it often costs more. Depending on your specific needs, environment size and budget, there must be a cloud storage option for you.
