Unlike a public cloud, which serves many clients at once and provides all its users with a limited set of standard services, each private cloud serves only one organization.
The hosted organization can specify a list of permitted users and assign various system access permissions to its business partners, but basically a private cloud is a platform that belongs to, and serves, solely the one organization that owns it. When a business or other organization uses a private cloud platform, it does not share resources with other users and it is not restricted by the standards that public clouds impose on their many users.
Which cloud do you need? Private or public?
Unlike public cloud platforms, which are located at the provider’s site, private cloud platforms are located — depending on the client’s needs — on premises or hosted in a collocation services. The decision as to which type of cloud the organization should or must have is no minor decision. A private cloud has many advantages, but the considerations that govern the decision differ from one organization to another and dependent on the organization’s size, business structure, business content (the nature of the core business processes), work requirements, and work processes.
For instance, if at Organization A the IT infrastructure is partially virtual and does not require a cloud platform for day-to-day operation, a private cloud platform is much less necessary than for Organization B which deals constantly with e-commerce as the lion’s share of its work. Organization A can make do with a public cloud platform and can decide to move onto a private cloud if and when its day-to-day business processes become more heavily electronic. For Organization B, in contrast, using a private cloud platform is very important because in the organization’s day-to-day work, a public cloud cannot provide the same advantages and cannot add the same value.
What advantages does a private cloud platform bring?
First and foremost, a private cloud is designed exclusively for its owner and adapted precisely and individually to the owner’s needs. No one organization resembles another exactly in terms of the structure of its business, the interplay of its work processes, or the configuration of its data store — not even when the organizations operate in the same field, in the same industrial environment, and apparently with similar parameters.
- Individualization— Each organization has work methods of its own, a different internal structure (departments, branches, etc.), differently designed work processes, and different supply chains, production, marketing, and sales. These differences give a clear advantage to an organization that chooses a private cloud tailored exactly to its requirements and providing its employees with a virtual work environment that is familiar and efficient.
- Workload balancing— Because the private cloud as a work platform is customized to the needs of the organization using it, and because there are no other users making demands on the same cloud, no overload from outside the organization can interfere — slowing, disrupting, or even halting work — the way it may interfere on a public cloud.
- High-quality data security — choosing a private cloud, the organization can enjoy more peace of mind than an organization or business that chooses a public cloud. The data security options, the means of caution, and the encryption and coding abilities that a private cloud service makes available are greater than can be implemented on a public cloud. The infrastructure and data store themselves are physically separated from those of other organizations, creating difficulty for anyone wishing to harm the organization’s sensitive data store or to access it without permission.
- Keeping the technology current — When a private cloud is provided and administered by an infrastructure company outside the organization, the cloud can be kept constantly at the most advanced technological level, updated and upgraded with no direct investment from the organization. It must be noted that this advantage belongs only to organizations that use external infrastructure providers. Such providers always strive to supply optimum service to their clients and to stay absolutely up to date (in order to nurture their clientele and preserve long-term client relationships). The situation differs, of course, when the private cloud platform is owned and operated exclusively by the organization itself. In the latter case, the organization must itself make the investment in updating or upgrading the system.
- Increasing resources to meet the organization’s needs — Like the previously listed advantage, this advantage too derives only from private clouds provided and administered by external infrastructure providers. Because the international business marketplace is trending toward specialization, the advantage is all the greater. The working assumption is that if an organization is already paying an external infrastructure provider anyway (in order to save the expense of constructing an in-house IT department and of dealing with infrastructure and updates), it will not want to undertake the bother and spend the valuable time involved in expanding its resources and purchasing hardware, infrastructure, and all the rest.
Who is the private cloud intended for?
If in the past only huge organizations purchased private cloud platforms for themselves, today in contrast the use of private clouds is growing even in smaller and younger businesses.
Because the platform is administered, continually updated, and upgraded by the cloud provider as a matter of routine, the organization can design whatever platform is appropriate for itself even if the business is only starting out, and can expand or change it in accordance with its pace of growth.
The unique nature of the cloud platform makes it flexible and open to changes and updates. All clouds are open in this way, even the public clouds that offer standardized services to a wide-ranging clientele.
