Private Cloud VS Public Cloud: What Is the Right Choice for Your Business

Private cloud computing is a form of cloud computing that is used within a corporate firewall, and is controlled by a company’s IT department. Private cloud computing therefore provides greater data security, however the company also takes on the possible risk of natural disasters such as server crashes, workplace fire, or water damage.

Public cloud computing involves the use of a third party service to utilize their servers or data storage facilities as an alternative to the cost of supercomputers or the pitfalls of private cloud computing systems. The third party service also takes on the risks associated with having and maintaining the servers.

Differences between Public cloud computing and Private cloud computing

Private clouds involve a dedicated, in-house IT department setting up and managing the cloud hardware. This may be costly for the company to upscale, in the case of diminishing performance. On the other hand, public clouds work on a “pay-as-you-need” basis, whereby a company can select which data storage and server would be the best fit for the company. This also allows companies to upscale at a relatively lower cost than that of private clouds, as the hosting company needs to maintain up to date services.

Another difference between private clouds and public clouds is that public clouds follow certain compliance procedures on the types of data that can be stored and distributed within a company, whereas private clouds may distribute data freely and store data as they please because they do not need to comply with the policies that are set out.

The cost of setting up and maintaining the best private clouds can be costly as the company has to purchase all hardware that is necessary to set up and manage an internet server. The motherboards and other hardware used for these servers can cost a fortune, especially with companies needing to acquire more power to keep the systems running all through the year. Therefore, power cost and the cost of space will also be more significantly more than that of public clouds. Public clouds offer a large range of hardware to choose from when purchasing off site server or storage space, with greater performance.

The risk involved in using a private cloud, instead of a public one is worth considering.  A private cloud could lose all the company’s hardware and storage in a disaster, and backing information up, adds additional cost to the value of equipment. Public clouds have lower risk involved as storage and hardware are protected at an offsite environment, and in the unlikely event that information is lost, the company would only lose information, and not precious hardware. The risk in loss of hardware lies solely on the data hosting company.

The labor involved in having a private cloud and the costs involved are the final difference between the two business solutions. For private cloud systems, a larger group of IT individuals must be onsite to set up and maintain the servers; whereas with public clouds, a smaller IT department can be used as the servers are constantly maintained by another company. Therefore, a company using a public cloud can afford to employ fewer workers in their IT department, and would only need to liaise with the public cloud company and focus the rest of their time with internal IT issues, due to the very nature of internet-based computing.

Each cloud computing solution offers its own positives and negatives, although some companies opt to go for hybrid clouds, which is a mixture of public and private cloud computing, utilizing the positives of both systems.
