Read what is public cloud and private cloud, and explore the difference between public cloud and private cloud.


The main difference between public cloud and private cloud is that a private cloud is meant to extend a company’s data center and is only accessible to that company’s employees. In contrast, a public cloud shares its fabric with multiple organizations.

What is a Public Cloud?

The public cloud is a space where physical or digital assets used for storage management, such as servers, software, and other associated infrastructure, are owned by a cloud service provider that manages these assets over the Internet.

In the public cloud, users can share the hardware, storage, and network devices with other organizations that have contracted a plan with the same provider. You will access your company’s information through a unique username and password. The most common way to access information in the public cloud is through a web browser or its official app.

You can securely manage email accounts, office apps, and storage with public clouds. Some examples of public cloud providers include Dropbox, Google Drive, Microsoft OneDrive, etc.

Advantages of Public Cloud

Low cost: You can contract a fixed-price monthly or annual plan where it is not necessary to purchase hardware or software.

Insured maintenance: The provider will take care of the maintenance of the storage servers.

Reliability and security: Due to the extensive network of servers, your company’s data is replicated, guaranteeing no problems arise.

Public clouds are easy to use when it comes to setting up and managing.

What is a Private Cloud?

The private cloud can be physically located in your company’s local data center or hosted in the cloud service provider’s data center. This cloud comprises all the computing resources used exclusively by a company. These resources include hardware and software while the infrastructure is maintained in a private network.

Private clouds are widely used by government agencies, financial entities, and any medium or large organization that requires more significant control over its essential operations.

Companies choose the private cloud because it allows customizing solutions according to their resources and specific information management requirements.

Advantages of Private Cloud

The primary benefit of using a private cloud is its incredible data security and compliance capabilities. Here are some other vital advantages that the private cloud offers:

Flexibility: The company can customize the cloud environment to meet the primary and specific business needs in managing its information.

Greater security and control: Resources are not shared with third parties. Therefore you can count on security levels and manage access only to authorized personnel for their administration.

Assured scalability: The possibility of scaling the company’s technological potential according to its needs is more significant compared to the infrastructure of the local environment.

Optimal data transfer: You get a better speed through a private link.

Difference Between Public And Private Cloud

The main difference between the public and private cloud is where it is hosted and who manages it. Public cloud uses a shared infrastructure, while private clouds use your organization’s dedicated infrastructure. 

Other standard cloud models include hybrid cloud, which combines public and private clouds, and multicloud, whereby customers use cloud services that span multiple public clouds.

Public cloud platforms pool resources in data centers distributed worldwide that multiple companies and users can access from the Internet. 

Instead of an internal team, public cloud providers manage and maintain the underlying infrastructure. As a result, leveraging public cloud services reduces IT operating costs and frees up time for teams to focus on valuable work that directly benefits the business.

The private cloud requires a higher initial investment since it is a complete solution for the company, while the public cloud is based on a subscription model.

In addition, the public cloud depends on the public Internet, which can lead to instability. On the other hand, the private cloud offers higher performance for being a localized site as long as it receives proper maintenance.

Public Cloud Vs. Private Cloud

  Public Cloud Private Cloud
Services  A single organization or company can only take access to the services offered. Different organizations or people can share resources and services.
Performance  Reduced performance due to its multi-user nature. High performance.
Customization  Limited customization capabilities. Highly customizable.
Costs  Services in a public cloud are cheaper than in a private cloud. Expensive.
Infrastructure  The infrastructure will always be hosted on the premises of the cloud service provider. The infrastructure is usually located within the organization and involves certain installation costs.
Security  Basic compliance and data security. Highly secure.
Control over Infrastructure Public cloud environment offers limited control over the infrastructure. A private cloud environment offers complete control over the infrastructure.
Hosted by  AWS, Dropbox, Google Drive, or Microsoft OneDrive. Microsoft KVM, HP, Red Hat & VMWare, etc.
Connection Connected to the public Internet. Provides connectivity over the private network only.
