What is the public cloud? What are the public cloud providers in China?

A public cloud is typically a cloud that is available to users by a third-party provider, and is generally available over the Internet and may be free or inexpensive. There are many instances of this cloud that can be served across today's entire open public network. As a support platform, the public cloud can also integrate upstream service providers (such as value-added services, advertising) providers and downstream end users to create a new value chain and ecosystem.

Public clouds are generally available to users of third-party providers, are generally available over the Internet, may be free or inexpensive, and have many instances of this cloud that can be served across today's open public networks.

The meaning of the existence of the public cloud

The biggest significance of public cloud is to be able to provide attractive services to end users at low cost, create new business value, public cloud as a support platform, but also to integrate upstream service providers (such as value-added services, advertising) providers and downstream end users, to create a new value chain and ecosystem.

The core feature of public cloud is that the ownership of infrastructure belongs to the cloud service provider, and cloud resources are open to the public, and any qualified individual or organization can lease and use cloud resources without the operation and maintenance of underlying facilities. The advantages of public cloud are low cost, no maintenance, easy to use and easy to expand, which can meet the needs of most customers such as individual users and Internet enterprises.

According to the service level, cloud computing can be divided into three levels: Laas, PaaS and SaaS

1、laas

Infrastructure and services: Cloud service providers build and operate IT system infrastructure (including computer rooms, networks, disk cabinets, servers, etc.), and provide customers with basic computing resources such as computing, storage, and network in the form of services, in which users can use IT

The resource runs software such as operating systems and applications. The most prominent feature of this model is that users do not need to build expensive IT infrastructure on their own; In addition, this model increases the flexibility of users to use IT resources, thereby reducing waste.

2、paas

Platform-as-a-service, cloud service providers build and operate software development platforms on the basis of underlying IT resources, and provide customers with a wealth of application development tools, application operating environments, application hosting, operation and maintenance services. The advantage of this model is that developers can easily access a variety of mature software development, testing, and operation and maintenance tools, thereby simplifying the development process and reducing repetitive work.

3、saas

Software-as-a-Service, where cloud service providers develop applications in the cloud or migrate existing software to the cloud, and provide applications to customers on a subscription basis. After subscribing to the software services of the cloud service provider, the user connects to the network through the cloud terminal device, and then directly uses the software through a web browser or programming interface.

What is the difference between the public cloud and the private repentantThe objects are differentThe public cloud** has great advantages and is suitable for all enterprises, especially startups and individual users.

Private cloud is more secure and suitable for large enterprises and institutions.

The business scenarios are differentA private cloud is mainly for internal enterprises, and its users are mainly internal employees.

The technical architecture is differentThe public cloud self-developed architecture, focusing on distribution, and gathering the reputation of the group.

Compatibility is differentWhen using the public cloud, you need to modify your business according to the requirements of the public cloud to achieve adaptation.

Private clouds can be actively compatible and adapted to their own business.

Security is differentThe public cloud mainly implements security isolation through the host layer.

The private cloud is isolated through the network layer.

According to the deployment model, cloud computing can be divided into public cloud, private cloud, hybrid cloud, community cloud and public cloud.

(1) Private cloud. Cloud resources are only available to users within one organization, which is a core feature of a private cloud. However, there are no strict rules on who owns the cloud, schedules and operates the cloud, and it may be the unit, a third-party organization, or a combination of the two.

The cloud may be located within your organization or hosted elsewhere.

2) Community Cloud. Cloud resources are dedicated to users in a fixed number of organizations that have the same requirements for the cloud (such as security requirements, cloud mission, rules and regulations, compliance requirements, etc.). The ownership of the cloud and the operation of daily management may be one or more units within the community, or it may be a third-party organization outside the community, or it may be a combination of the two.

The cloud may be deployed on-premises, or it may be deployed elsewhere.

3) Public cloud. Cloud resources are developed for the public to use. The ownership, day-to-day management and operation of the cloud can be a commercial organization, academic institution, ** department, or several of them.

The cloud may be deployed locally or elsewhere, for example, the cloud of the Zhongshan Citizen Public Cloud may be built in Zhongshan or Shenzhen.

Private clouds – built for individual use by a single customer user, providing the most effective control over data, security, and quality of service. The customer user owns the infrastructure and has control over how applications are deployed on that infrastructureThe core attribute of a private cloud is dedicated resources。(e.g. Zhiku Cloud, etc.).

Hybrid cloud – combines the best of both public and private clouds. For data security reasons, enterprises prefer to store data in a private cloud, but at the same time want to have access to the computing resources of the public cloud, in this case hybrid cloud is increasingly adopted, it will:Public and private clouds are mixed and matchedto maximize the benefits

Summary: Public cloud - shared resource services at a low cost.

Private cloud – dedicated resources, data security.

Hybrid cloud – the cost benefits of both public cloud and data security in private cloud.

Hello, what are the advantages of public cloudWhat are the reasons why some enterprises are reluctant to go to the public cloud for your answer: (1) Security, cloud computing provides the most reliable and secure data storage center, and users no longer need to worry about data loss, virus invasion and other troubles. (2) Convenience.

Cloud computing has lower requirements for the user's equipment and is the most convenient to use. (3) Data Sharing. Cloud computing makes it easy to share data and applications across devices.

4) Infinite positive fibrillation possible. Cloud computing provides people with an almost unlimited level of horizontal scaling possibilities for the use of ** and hardware, and users can flexibly purchase resources according to their needs and obtain them quickly.
