Cloud computing is a technology trend that is increasingly popular and widely adopted by many businesses in the current era of digital transformation, thanks to the outstanding benefits it brings. Cloud computing allows businesses to store and access data, applications, and resources over the internet instead of relying on traditional servers and physical infrastructure. This enables businesses to enhance flexibility, save costs, and strengthen remote accessibility.

Firstly, let's explore what cloud computing deployment models are. The cloud computing deployment model determines how applications and data are stored, managed, and accessed in the cloud computing environment. There are various deployment models, and selecting the right one for a business is crucial. Here are the 5 main deployment models:

Public Cloud
Private Cloud
Hybrid Cloud
Community Cloud
Multi-cloud

By understanding these deployment models, we gain an overview of how businesses are adopting and implementing cloud computing. Let's continue to explore the details of each model with VNG Cloud in this blog post!

Top 5 main cloud computing deployment models

Public Cloud

Public cloud is a widely adopted cloud computing deployment model where computing services are provided to multiple organizations and individuals over the internet. In this model, the cloud service provider owns and manages the computing infrastructure, including servers, storage, network, and other services, and users can access and use these services on-demand.

Benefits of Public Cloud

Flexibility: Users can easily scale services up or down according to the actual needs of the business. This flexibility allows businesses to enhance their ability to respond quickly to resource demands or cost reductions.
Cost Savings: Public cloud computing helps businesses save costs on purchasing, managing, and maintaining physical infrastructure. Instead of buying individual servers and storage, users only pay for the services they use.
Remote Access: With public cloud computing, users can access and manage data and applications from any location with an internet connection. This enhances the business's ability to work remotely and flexibly manage and access data.

Limitations of Public Cloud

Security: One limitation of public cloud computing is concerns about the security and protection of data. Because the business's data is stored on public cloud infrastructure, there is a risk of information leakage or network attacks. Ensuring data security becomes a significant issue when using public cloud computing.
Dependency on Service Providers: Businesses using public cloud computing must depend on service providers to ensure the stable and reliable operation of services. If the service provider encounters issues or disruptions, it may impact the business's ability to access and use the services.

Private Cloud

Private cloud is a cloud computing deployment model in which a business builds its own private cloud infrastructure within its organization. This infrastructure can be deployed in the business's own data center or on dedicated servers. The private cloud model provides high privacy and security, allowing the business to have complete control over its data and applications.

Benefits of Private Cloud

Privacy and Security: The private cloud model allows businesses to retain complete control over their data and applications. This helps protect the critical information of the business and meets security and compliance requirements.
Customization and Flexibility: Businesses can customize their private cloud computing infrastructure according to specific needs.
High Performance: The private cloud computing model enables businesses to efficiently utilize internal resources and computing power, effectively meeting the business's needs.

Limitations of Private Cloud

High Costs: Building and maintaining a private cloud computing infrastructure may require investment in hardware, software, and IT personnel. Therefore, the private cloud model tends to have higher costs compared to public cloud computing models.
Scale Limitations: Private cloud models often have scale limitations compared to public cloud models. Businesses need to ensure that their private cloud computing infrastructure has sufficient resources to meet their needs.

Hybrid Cloud

In the Hybrid Cloud model, businesses combine the use of both public cloud and private cloud computing models to store, manage, and process their data and applications. This model allows businesses to use public cloud computing technology for less sensitive tasks and use private cloud computing technology for tasks that require high privacy and security.

Benefits of Hybrid Cloud

Flexibility: The Hybrid Cloud model allows businesses to leverage the flexibility of public cloud computing and the privacy of private cloud computing. Businesses can easily scale services up or down according to their actual needs, enabling them to quickly respond to resource demands or cost reductions.
Security and Privacy: The Hybrid Cloud model allows businesses to maintain the privacy and security of sensitive data. Tasks requiring high privacy and security can be performed on private cloud computing infrastructure, while less secure tasks can be carried out on public cloud computing infrastructure.
Performance and Scalability: The Hybrid Cloud model enables businesses to leverage the resources and computing power of both public and private cloud computing technologies. Businesses can use public cloud computing for resource-intensive tasks and private cloud computing for tasks with smaller resource needs. This optimizes performance and meets the goals and requirements of the business.

Limitations of Hybrid Cloud

Complexity in Management: Managing a Hybrid Cloud model can be complex for businesses as it involves handling both public and private cloud computing models. Businesses need specialized knowledge and skills to effectively manage and operate both models.
High Costs: Building and maintaining a Hybrid Cloud computing infrastructure may require investment in hardware, software, and IT personnel. Therefore, the Hybrid Cloud model tends to have higher costs compared to public or private cloud computing models.

Multi-Cloud

Multi-Cloud is a cloud computing deployment model in which businesses use multiple different cloud service providers to store, manage, and process their data and applications. Instead of relying on a single provider, businesses leverage resources from multiple cloud service providers to enjoy the specific benefits each provider can offer.

Benefits of Multi-Cloud

Resource Diversity: Using the Multi-Cloud model allows businesses to leverage resources from various providers, diversifying infrastructure and resources. This helps avoid dependence on a single provider and takes advantage of the unique benefits each provider can bring, including flexibility, performance, security, and economic value.
Latency Reduction: To reduce latency and improve user experience, businesses can choose cloud computing regions and areas from service providers that are close to their customers.
High Availability: It is rare for two separate cloud service providers to face issues simultaneously. Therefore, deploying Multi-Cloud enhances high availability for business services.
Optimizing Performance and Cost: Businesses can choose the most suitable provider for each task based on specific requirements. This helps optimize performance and costs for each specific job.

Limitations of Multi-Cloud

Complex Management: The Multi-Cloud computing model requires businesses to manage and operate resources from various cloud service providers. This demands specialized knowledge and skills to efficiently manage and optimize the use of resources from multiple providers.
Compatibility Issues: Some applications and services may not be compatible or may be difficult to integrate with multiple cloud service providers. This can cause challenges in transitioning and integrating between providers.

Community Cloud

Community cloud is a cloud computing deployment model in which organizations or businesses share the same cloud infrastructure to meet their common requirements and goals. This model is often used by organizations or businesses with shared needs and regulations, such as organizations in the same industry, the same geographical area, or with similar legal requirements.

Benefits of Community Cloud

Resource Sharing: The Community Cloud model allows organizations or businesses to share the same cloud infrastructure. This efficiently utilizes resources, minimizes costs, and improves scalability and performance.
Cost Optimization: Using Community Cloud computing helps minimize costs related to building and maintaining private cloud computing infrastructure. Instead of each organization or business investing fully in private infrastructure, they can share costs with other members in the community.
Enhanced Security: The Community Cloud model allows organizations or businesses to share responsibilities and resources related to security. This helps strengthen the ability to meet security requirements and compliance regulations within their industry or specific geographical region.

Limitations of Community Cloud

Complex Management: The Community Cloud computing model requires coordination and tight management among members. Businesses need to ensure they adhere to common rules and regulations and effectively collaborate with each other.
Dependency on Partners: This model also requires dependence on partner cloud service providers. This may pose risks of disruptions or issues if a partner cannot meet requirements or operates unstably.

Cloud Computing Service Models

In addition to deployment models, there are three popular cloud computing service models:

IaaS (Infrastructure as a Service): This service provides computing infrastructure such as servers, networks, and storage. Customers have full control and management of applications and data on this infrastructure.
PaaS (Platform as a Service): This service offers a development platform for customers. Customers can focus on developing applications without worrying about managing the infrastructure.
SaaS (Software as a Service): This service delivers ready-to-use software applications over the internet. Customers can access and use applications without the need for installation or management.
