Public Cloud Vs. Virtual Private CloudThe concept of cloud computing is one that has entered the national discussion, particularly as it impacts businesses that must invest in new telecommunications and internet services to remain competitive.

One of the first comparisons a business owner must examine is that of virtual private cloud computing versus public cloud computing.

There are even hybrid cloud options that allow a company to take advantage of both configurations. Each option provides specific advantages, and it’s important to investigate the options for each before making a decision on installation with your cloud services partner.

Here’s what you need to know about the public cloud versus the virtual private cloud


What’s the Difference Between a Public Cloud and Virtual Private Cloud?

First, the public cloud. The public cloud is a service that’s delivered via an Internet connection. Public clouds are meant for use by the masses and offer very little customization options. One of the reasons it’s important to fully investigate public cloud providers is because their resources can become strained when they’re oversubscribed.

When is it Appropriate to Choose the Public Cloud?

One of the most common reasons a business will choose the public cloud is when a company needs an inexpensive storage option. When response time and access to the data isn’t important, a public cloud is an ideal and affordable option.

On the other hand, a virtual private cloud is a setup where a business knows exactly where its data is stored, and there aren’t issues with oversubscription and reduced performance levels. A virtual private cloud is also different from a public cloud in that providers offer subscribers greater flexibility and customization.

When is It Appropriate to Choose the Virtual Private Cloud?

Clients who need a secure option that also offers fast response time and good performance will often choose the virtual private cloud. A company may incur higher monthly costs when using the virtual private cloud.

Comparing Security Levels Between the Public and Virtual Private Cloud

Business Cloud Storage

Security is a universal concern for all businesses. The type of data stored or applications utilized by a company will usually influence whether the moderately secure option of the public cloud is best or whether the highly secure option of the virtual private cloud is suitable.

One of the reasons why data stored on a virtual private cloud is more secure is because a business isn’t sharing resources with any other company or individual when accessing and utilizing the cloud. This lack of competition for access to the cloud means there is less of a chance that data will become compromised.

Control and Flexibility of the Virtual Private Cloud and the Public Cloud


The public cloud is accessed by many users, and resources are shared within it. With this sharing, each user has very little control over the underlying infrastructure, and updates to the hardware will impact everyone associated with that public cloud.

On the other hand, a virtual private cloud offers the user (your company) more control over the technology utilized, as well as over the resource allocation and load balancing. After examining a user’s usage patterns and resource consumption, the service provider can modify the resource allocation for the virtual private cloud.

A Hybrid Approach is Common with the Cloud

Not surprisingly, a public cloud is less expensive than a virtual private cloud, and many companies will carefully consider the advantages of using the least expensive cloud option. SMB will often approach cloud computing from the standpoint that both types of cloud options provide value.

Using both a virtual private cloud and a public cloud means a company can utilize an affordable public cloud for non-sensitive data and a virtual private cloud for data that requires a high level of security.
