In today’s competitive environment, organizations strive to search for ways to enhance their IT functionalities. As a result, they move towards outsourcing different platforms and infrastructure through the public cloud, and at the same time maintaining sensitive data in private clouds. Cloud computing has given several enterprises the edge. It allows these businesses to be more productive in the way they do things. As a result, this option creates a cost-efficient alternative as compared to purchasing and maintaining an infrastructure for keeping data.


The trend these days involves people focusing more on the core competencies of their company, instead of spending money on purchasing hardware. They have shifted to a view of thinking that believes IT services are more of a commodity which can be bought from the cloud.

The Benefits Offered By Cloud Services


  • It has a good future. According to studies, it is expected that the revenue created by the cloud market is expected to increase at 36% CAGR (Compound Annual Growth Rate) by the end of 2016.
  • Cloud technology is elastic. This is advantageous considering the fact that data can either grow or shrink.
  • Rather than purchasing and owning it, cloud services can be rented. Because of this, it is possible to avoid big investment expenditures.


There is no doubt that cloud technology has played a big role in the IT industry. It is even referred to as a natural evolution in the field of Information Technology. Still, within the technology itself, there is a battle between two kinds of platforms, Private and Public Clouds. What are the differences? Which is better?


Public Cloud


A public cloud is composed of a service, or a group of services purchased by an organization or a business through the Internet by means of a third party provider. These kinds of services use processor power and storage capacity, which is not really owned by the organization itself. These facilities are either owned by the vendor itself, or a third party cloud infrastructure.


Private Cloud


A private cloud is generally the extension of the organization or business’ data center. It is used to provide processor power and storage capacity for different functions. As a matter of fact, being ‘private’ means more than just being a ‘non-shared’ resource. It also provides extra security advantage to an organization.


Considerations between Public and Private Clouds


Both types of cloud platforms have implications, management wise. However, whichever type is selected by a business means a significant offload in management responsibility.


In a public cloud environment, the capital expenditure is nearly completely eliminated. The burden is diverted to a fee-for-service, which is often based on data volume and utilization. Securing and maintaining a public cloud infrastructure lies in the hands of the vendor, thus enabling the organization to streamline their IT operations, and at the same time minimizing money and time used on the upkeep of the system.


In a private cloud environment, there is a huge demand on resources, which are used to purchase, specify, update, house, safeguard, and maintain the infrastructure itself. This can create a big initial capital expenditure, along with subsequent investment, which is required in adding new capacity and equipment.


As of this point, there is still a persistent concern about security. Professionals in the IT industry are confident and have placed their trust in the cloud service providers as they show a great amount of security and transparency in their services. Bottom line is, this technology is relatively new, considering its existence in the industry since its conception. There are still a lot of things that can be expected from it, and different enterprises are eagerly waiting for such enhancements to finally surface and create an impact in the way their businesses are handled.
