Talking about the advantages and disadvantages of public cloud, private cloud, and hybrid cloud

Public cloud
Public cloud is the most common way to deploy cloud computing.
Public cloud resources (such as servers and storage space) are owned and operated by third-party cloud service providers, and these resources are provided through the Internet.
In the public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider.
In a public cloud, you share the same hardware, storage, and network equipment with other organizations or cloud "tenants."
You can use a web browser to access services and manage accounts.
Public cloud deployment is usually used to provide web-based email, online office applications, storage, and testing and development environments.
Advantages :
(1) Convenient. Cloud computing has the lowest requirements for user equipment and is the most convenient to use.
(2) Easy to expand. Provides almost unlimited space for storing and managing data.
(3) Stability: 5-line full dynamic BGP: Huawei is the only network cloud vendor in China that provides 5-line full dynamic BGP, which can effectively respond to failures, adapt to network changes, automatically switch network links, and provide better support The conduct of your business.
(4) Security: Neutrality: At the global press conference of Huawei Cloud Computing, it declared that it "does not touch applications or data" and is a neutral service provider.
(5) End-to-end: Huawei is the only cloud service provider that provides end-to-end service capabilities. From the underlying physical equipment to the upper-level virtualization construction, they are all independently developed products by Huawei, which have stronger product service capabilities.
(6) Security certification: Huawei has passed the trusted cloud certification, the Cloud Security Alliance C-STAR, the Ministry of Public Security and other security certifications.
Private cloud
private cloud consists of cloud computing resources dedicated to an enterprise or organization. The private cloud can be physically located in the organization's on-site data center, or it can be hosted by a third-party service provider.
However, in a private cloud, services and infrastructure are always maintained on the private network, and the hardware and software are exclusively used by the organization.
In this way, private clouds make it easier for organizations to customize resources to meet specific IT needs.
Private clouds are usually used by government agencies, financial institutions, and other medium to large organizations that have business-critical operations and want greater control over the environment.
Advantages:
(1) Autonomous and controllable. The private cloud is built for the sole use of a customer, belongs to only one user, and is fully controlled.
(2) Data privacy is good. It is safest to keep important data in your own home:)
Disadvantages :
(1) High cost. Building a private cloud may include upfront costs, usage fees and maintenance and management resources. Therefore, the cost is relatively high.
Hybrid cloud
Hybrid cloud is generally considered the "best of both worlds". It combines local infrastructure or private cloud with public cloud, and organizations can take advantage of the advantages of both.
For example, the Xingyun Butler hybrid cloud management platform not only supports mainstream public cloud vendors in the industry, such as Huawei Cloud, Alibaba Cloud, etc., but also connects the enterprise's internal private cloud to the cloud to easily complete hybrid cloud management.
In a hybrid cloud, data and applications can be moved between private and public clouds, providing greater flexibility and deployment options.
Advantages :
(1) Controllability. Organizations can maintain a private infrastructure for sensitive assets.
(2) Flexibility. Other resources in the public cloud can be used when needed.
(3) Cost-effectiveness. With the ability to expand to the public cloud, you can only pay for additional computing power when you need it.
(4) Easy and effortless-you can switch to the cloud without time and effort, because you can gradually migrate according to the workload according to time.
