For businesses, Cloud Server is the optimal solution to replace traditional forms of storage servers, to increase availability, data security and optimize usage costs.
However, when it comes to Cloud Server, we will need to consider between two important models: Public Cloud (regular cloud services) and Private Cloud (more advanced) to optimize the best usability.
In this article, AZDIGI will help you analyze and learn more about these two concepts.
1. Introduction to Public Cloud and Private Cloud
1.1 Overview of Cloud Computing
Cloud Computing is a technology model that allows access and use of computer resources such as storage, processing, and software over the network instead of having to invest in physical infrastructure. Instead of managing and maintaining bulky hardware systems on-site, businesses can rent and use these services from cloud providers at reasonable costs and flexible scalability .
In today’s business environment, Cloud Computing plays a vital role in improving operational efficiency, reducing costs, and increasing agility as businesses scale. It also helps businesses adapt to rapid market changes, while providing a solid foundation for digital initiatives such as data analytics, artificial intelligence, and remote work.

And in Cloud Computing in general, there are two types of cloud services that are quite popular today: Public Cloud and Private Cloud.
1.2 Overview of Public Cloud and Private Cloud
Public Cloud and Private Cloud are two popular cloud types when classifying cloud servers, each serving different purposes and needs of businesses.
Public Cloud : is a cloud computing service provided by cloud server service providers such as: Amazon Web Services, Google Cloud, AZDIGI,… In this model, resources such as servers, storage, and networks are shared among many users, helping to save costs. Public Cloud is suitable for small and medium-sized businesses, or organizations that need to deploy quickly without requiring a high level of security. Users can access services over the internet and only pay for the resources they use.
Private Cloud : is a cloud computing environment designed specifically for a single organization or business. In this model, all cloud resources will not be shared with any other users, helping to increase security and control. Private Cloud is usually deployed in the organization’s data center or through a third-party service provider but is still under the control of the business. This type is suitable for large organizations, industries with high security requirements such as finance, healthcare, or businesses that need to customize the infrastructure according to specific needs.
2. Definition and Mechanism of Action
2.1. Public Cloud
Definition: Public Cloud is a cloud computing model in which resources such as servers, storage, and networks are shared among many different users. These resources are provided and managed by cloud service providers such as AWS, Microsoft Azure, or Google Cloud. Users can access these services over the internet and only pay for what they use, reducing costs and increasing scalability. The Public Cloud model offers flexibility and convenience, suitable for businesses that want to deploy services quickly without investing in their own hardware infrastructure.
How it works: Public Cloud works on a resource sharing mechanism, where servers, storage and networks are provided and managed by cloud service providers. Resources are shared among multiple users through virtualization technology, with virtualized servers operating on the same physical infrastructure. Users access resources over the internet and only pay for what they use, helping to optimize costs. The service provider is responsible for security and infrastructure management, while users can automatically scale up or down resources as needed.
2.2. Private Cloud
Definition: Private Cloud is a cloud computing system designed specifically for a specific organization or business. In this model, all resources such as servers, storage, and networks are not shared with any other users, ensuring high security and control. Private Cloud can be deployed on-premises in the organization’s data center or through a service provider, but the organization has full control and customization of the infrastructure. This allows businesses to optimize and configure the system according to their specific needs, while meeting strict security and legal compliance standards.
How it works: Private Cloud works by providing dedicated server, storage, and networking resources to an organization, not shared with any other users. The system can be managed internally by the organization’s IT team or by a third-party service provider, but the organization still has complete control. This allows businesses to customize the entire infrastructure, from hardware configuration to security and data management, to meet specific needs and high security requirements.
3. Compare the differences between Public Cloud and Private Cloud
3.1. Quyền kiểm soát và quản lý
| Public Cloud | Private Cloud | |
| Control | Users have less control over the infrastructure and hardware because the resources are shared with many other customers. | Users have complete control over the entire infrastructure, as resources are dedicated to a single organization. |
| Manage | The cloud service provider manages the entire infrastructure, including security, maintenance, and upgrades. | Users can directly manage and customize the infrastructure, or hire a third party to manage it. |
Public Cloud is suitable for organizations that need flexibility, cost savings, and do not need to control the entire infrastructure, while Private Cloud is suitable for organizations that need more granular control, higher customization capabilities, and stricter security and policy compliance requirements.
3.2. Security
