Updated on November 19, 2014

3 Min Read

Cloud Computing Services are quickly making their way within organizations by virtue of their advantages such as scalability,instant provisioning, utility model etc. More than that Cloud computing has the ability to accommodate varying nature of businesses through its different deployment models i.e Public, Private and Hybrid.

Public Cloud vs. Private Cloud

Public vs Private:

Public cloud, as we mentioned earlier saves you from setup cost while its scalability and ‘pay as you use’ gives you complete freedom of storage and bandwidth. But due to its security concerns where you don’t know the location of your data has made many companies move to Private Cloud. They give you complete ownership and provides a complete dedicated cloud environment for the client. But private clouds are highly expensive and comes with high cost in terms of maintenance and resources.

Private environment in Public Cloud:

A pool of public cloud resources covered by the security protocols created for a private enterprise. The Virtual Private Cloud has brought in it the best of both public and private and is quickly making its place. So keeping in mind its objectives and uniqueness, we will, in this article compare two most commonly available subcategories of Cloud Computing – Virtual Private Cloud Computing and Public Cloud Computing.

Virtual Private Cloud Computing:

Virtual private cloud is one of the most abundantly found cloud computing solutions. The intrinsic flexibility of its paradigm makes it ideal for traditional enterprise IT requirements. Virtual private cloud has been adopted by industries such as finance and health care which have some of the most rigorous compliance requirements.

Public Cloud vs. Private Cloud

Salient Features of Private Cloud Computing

Enhanced Security Measures

Especially for financial institutions. Let’s take a bank or a mortgage company, for example. The confidentiality and security of their critical data is the utmost concern. Virtual private cloud computing comes equipped with a customizable firewall and authenticated tools which ensure maximum protection against unauthorized use, hacking and other such malicious attempts.

Dedicated Resources

The essence of private cloud is “no compromise”. As a subscriber to private cloud computing an enterprise has its own dedicated resources such as processor time and data storage which ensure optimum performance.

Greater Customization

Private cloud services are customizable so they can be molded to suit the exact requirements of an enterprise. This in turns bestows the enterprise with more control over their data.

Drawbacks of Virtual Private Cloud

The enhanced security, customization and dedicated resources aspects of a virtual private cloud can be expensive for small businesses. Plus with all these features comes great responsibility of maintenance, for which you might need to look for managed cloud services.

Public Cloud Computing

Cost effective, “pay as you use” and simplicity are some of the most notable features of Public Cloud Computing. It’s the easiest of cloud solutions to setup and maintain and is the preferred choice of most small scale and start-up enterprises.

Salient Features of Public Cloud Computing

Cost Effective:

A public cloud is the most simplest to setup as it liberates that subscriber from woes of hardware, application and bandwidth expenses. These are all taken care of by the service provider. There’s no rigid contract that would dictate a fixed amount to be paid and enterprises pay for only those resources they are utilizing.

Complete Freedom:

Public clouds give you complete freedom. They provide with necassary resources and you can utilize them the way you want. This is the reason public clouds are highly used when programmers wish to test any application or code work on short term basis.

Drawbacks of Public Cloud Computing:

Security and reliability are the biggest concern in public cloud. Public clouds are generally believed to easily hacked but they are ideal in situations where enterprises wishes to keep certain information to public at-large or in collaboration projects.
