Public vs Private Cloud Services: Basic Pros and Cons

May 5, 2022

Since the pandemic, you’ve probably heard a lot more about cloud computing than ever before. If you’re new to cloud computing, some of the acronyms and jargon can seem somewhat confusing at first. Two of the most common ones are public cloud and private cloud services. Here’s how these two services differ, along with their advantages and disadvantages.


In most cases, when people talk about cloud migration, they’re referring to a public cloud, as this is the one that’s the most popular, besides the most common. Put simply, the term “public cloud” refers to cloud computing services that are delivered to several organizations. It’s done over a public internet and can be free or charge or by pay-per-use.


There are several benefits for choosing public clouds, such as:

Talented engineers and updated technology

Public clouds are equipped with exceptionally highly skilled and proficient engineers. To be able to maintain an in-house data center you need to have a significant amount of capital investments for upgrading servers, besides security applications and software.

More affordable

Because you only have to pay for those services that you use, you don’t have to invest in expensive software or hardware. What’s more, there’s no maintenance to worry about as the upkeep is provided by a service provider. This makes public clouds more affordable. There’s also available on-demand resources that can meet the needs of your business.

Penetration testing

Consider how public clouds are required to go through penetration testing on a regular basis, and that their standards are considerably stricter than those required for private clouds. In fact, there are even some on-premise clouds that do not get penetration testing at any level that’s close to being acceptable.

Data recovery

Many business people prefer public cloud services because they don’t have to worry about losing data. A disaster recovery plan is typically complicated as well as hard to deploy, so this why many companies don’t want to use it. There’s minimal risk of data loss with public clouds. Your business can return back online quickly even when there’s a natural disaster.


Less security and privacy

One of the main issues with public cloud services is that they aren’t as secure and private. Although many public cloud services offer security, customers are worried about the company’s use of data. Often, there’s concern about third-party providers because they can come from foreign countries that have their own security laws.

Lack of control

When you use a public cloud service, you share the same infrastructure with others. Because the management and maintenance are done by your service provider, you don’t have any control.


Unlike a public cloud, which is accessible by several customers, a private cloud, which is also known as a corporate or internal cloud, is cloud computing whereby the software and hardware tools are only accessible by one customer or organization. In other words, it isn’t shared with other customers. On the other hand, public clouds are subscription services that offer their services to anyone who wants similar services.


Better security

Because private clouds operate on specific, physical machines, they’re easier to secure. Moreover, cloud access is safer since it uses network links that are more secure than what’s involved in public clouds. Additionally, consider that private clouds are behind firewalls, meaning there’s less odds of internet security risk.

More availability

Users can access the services of a private cloud virtually anywhere and anytime. In fact, private cloud services have a reputation for having an exceptional infrastructure that allows users maximum availability and control delivery.

Higher level of performance

As there isn’t any need for sharing between users, the rate of transfer is higher. Thus, private cloud services offer better performance.


More expensive

Private cloud-based services can cost more as there’s the expense of paying for servers, along with data centers, network infrastructures and software licenses. You also need to pay for an on-site staff for maintaining and looking after your cloud service.

Regular maintenance and time-consuming

In addition to costs for maintenance and set up, private cloud services also need hardware costs that entail regular upkeep. This can be both expensive and time-consuming.

Lack of support and deployment

Another disadvantage is that it can be extremely challenging to find qualified people to run the service. Finding support and deployment can involve more resources, taking longer to achieve its full potential.
