What is the private cloud model? A private cloud is a cloud computing model consisting of a separate and secure cloud environment to which access is dedicated to a single customer.
As with other cloud models, private clouds provide computing power as a service in a virtualized environment. They use a farm, called a pool, made up of physical computing resources. However, in the private cloud model, the cloud (the resource pool) is accessible only by one organization, giving it more control, protection, and privacy.
The technical mechanisms used to provide the different services that can be classified as a private cloud vary widely, which makes it difficult to define what constitutes a privately-owned cloud from a technical point of view. These services are generally categorized according to the different features they offer to the customer.
Private Cloud Features
The two features of the private cloud are the delineation of an environment cloud for the use of a single organization as well as a higher degree of network security. The private cloud is different from the public cloud, in which many customers access virtual services that all draw their resources from the same pool of servers across public networks. The private cloud services resources come from a separate pool of physical servers, which can be hosted internally or outside the enterprise, and accessed by private leased lines or secure encrypted connections over public networks.
The added security provided by the private cloud model is ideal for any type of organization or enterprise that needs to store and process private data or to perform sensitive tasks. For example, a private cloud service can typically be used by a financial company that is required by existing legislation to store sensitive internal data but also wants to use some of the benefits of cloud computing in its infrastructure, such as resources on request.
The Private Cloud Is Getting Closer To The Traditional Model
The private cloud model is closer to the traditional single LAN access model that companies have used in the past, but with the added benefit of virtualization. The features and benefits of private clouds are:
More security and confidentiality While public cloud services can provide a certain level of security, private clouds ensure that an organization’s operations are hidden from prying eyes, including using techniques such as a separate resource pool with restricted access to connections made behind an organization’s firewall, dedicated leased lines and/or internal on-site hosting.
More control Since the private cloud is only accessible by a specific organization, this organization will have the possibility to configure it and manage it according to its needs to reach a personalized network solution. However, such a level of control removes some of the economies of scale made possible by public clouds by centralizing hardware management.
Efficiency in terms of costs and energy; Implementing a private cloud model within an organization can improve the allocation of its resources internally, by ensuring the availability of resources to different departments and business functions, which will be able to respond to demand flexible and directly. Therefore, although they are not as cost-effective as public cloud services because of minor economies of scale and higher management costs, private clouds use computing resources more efficiently than Traditional LANs, as they reduce the investment in unused capacity.
This Not Only Saves A Company Money But Also Reduces Its Carbon Footprint.
More reliability even when resources (servers, networks, etc.) are hosted internally, creating virtual operating environments means that the network is more resilient in the event of individual incidents on the physical infrastructure. For example, virtual partitions can pull their resources from other unaffected servers. In addition, when the cloud is hosted by a third party, the organization can still benefit from the physical security of the infrastructure hosted in data centers.
In case of peak activity of the company. This service allows the provider to move some non-sensitive functions to a public cloud, freeing up space in the private cloud for sensitive functions that need it. It is even possible to integrate public cloud services with private clouds to form hybrid clouds, where non-sensitive functions are always assigned to the public cloud to maximize efficiency.
