What are the advantages of public cloud? What are the public cloud platforms?

There are three types of active cloud servers in the market, public cloud, private cloud and hybrid cloud.

The advantages of public cloud are mainly as follows: 1. Security. Cloud computing provides the most reliable and secure data storage center, and users no longer have to worry about data loss, virus intrusion, etc.

2. Convenient. Cloud computing has the lowest requirements for the equipment on the user side, and it is also the most convenient to use. 3. Data sharing.

Cloud computing makes it easy to share data and applications between different devices. 4. Infinite possibilities. Cloud computing offers an almost infinite number of possibilities for us to use the web.

Many small and medium-sized businesses are now choosing to use the public cloud, and the market value of the public cloud is increasing. In the case of public cloud, there are many options, such as Alibaba Cloud, Tencent Cloud, and Little Bird Cloud, which have a good reputation in public cloud.

Public Cloud Benefits:

Flexibility:When asked why they chose the public cloud, many companies chose flexibility. Under the public cloud model, new computing resources can be provisioned and deployed almost immediately, so the products and services of these companies can be brought to market or launched as soon as possible.

In addition, it is easy to change the composition of computing resources in response to changes in demand in later runs.

Scalability:As application usage or data grows, it becomes easy to increase computing resources based on demand. Many public cloud providers also include auto-scaling, so you don't have to think about when you want to add compute instances or storage – it's all done automatically.

Practicality:While the disruption of public clouds has affected its usefulness to some extent, there is a reason for this, as public clouds have to consider their large number of users – in general, public clouds take more time to run than traditional data centers and private clouds that rely on their own data centers. Many companies incorporate public cloud services into their business continuity (BC) and disaster recovery (DR) plans to enable remote data center operations and access and avoid potential natural disasters.

High Performance:When companies provide high-performance computing (HPC) for some of their tasks, the public cloud will make that part of the job easier, and customers will only pay for the features they need. Conversely, installing an HPC system in your own data center would be very expensive.

In addition, unlike small companies, which require long update cycles, large public cloud providers can install the latest applications and programs in their data centers.

Low cost:Because of their scale, public cloud data centers can achieve economics that are difficult for most companies to achieve. As a result, the pricing of public cloud service providers is usually at a fairly low level.

In addition to the purchase cost, users can also save on other costs through the public cloud, as they can reduce or eliminate the money used to hire IT managers. At the same time, users can get rid of the situation of constantly adding servers to meet the surge in demand. Moreover, the public cloud converts some capital expenses (one-time costs when purchasing hardware and software) into business expenses (recurring subscription fees), which will facilitate the presentation of data in the company's financial statements.

Location independence:Users can get public cloud services from any terminal device. As a result, companies can achieve high mobility among their employees and collaborate across geographical constraints, thereby improving overall productivity.

1. Introduction to the operation mode of the cloud computing industry

The cloud computing industry is classified according to the operation model, which can be divided into three categories: public sales cloud, private cloud and hybrid cloud. Among them, public cloud refers to the deployment mode in which the infrastructure is owned by an organization and provides cloud computing services to the public or an industry; Private cloud is a cloud computing deployment mode that deploys cloud infrastructure and software and hardware resources in the intranet for use by various departments in an institution or enterprise. A hybrid cloud is a combination of private and public clouds.

The scale of China's publicly-owned jujube cloud will reach 100 million yuan

Globally, the public cloud market is growing steadily. According to data disclosed by Gartner, in 2015, the global public cloud market size was about 178 billion US dollars; Driven by the need for remote work and cost reduction, the global public cloud market size reached $214.3 billion by 2019; In 2020, cloud spending is expected to grow rapidly in many regions as the economy reopens and more normal economic activities resume, with the public cloud market expected to reach $257.9 billion.

Domestically, according to data disclosed by the China Academy of Information and Communications Technology, from 2012 to 2019, China's public cloud market size almost maintained a growth rate of more than 40%. In 2019, the scale of China's public cloud market reached 100 million yuan, a year-on-year increase, and at the same time, in this year, the scale of China's public cloud market surpassed that of private cloud for the first time. According to **, in 2020, the scale of China's public cloud market will reach 100 million yuan.

3. China's public cloud IaaS market is mature

From the perspective of market segment size, in 2019, China's public cloud market is still dominated by IaaS services, accounting for an increase of one percentage point compared with 2018; However, the market share of SaaS services has declined, and the gap with the global market is large, so there is more room for development in the future.

Thank you. The public cloud is a cloud service connected through the Internet, the server is in the computer room of the cloud service provider, the user is the tenant, and the public cloud is like basic resources such as water, electricity and coal, but for different types of enterprises, the importance and necessity of the public cloud are also different.

For micro, small and medium-sized enterprises, the public cloud will be the optimal solution. The investment of basic resources, the configuration and maintenance of the basic environment, the cost of labor and hardware will greatly restrict the innovation speed and core business progress of small and micro enterprises. The public cloud provides a complete set of product solutions and security protection to meet security requirements and business resilience at all levels.

For large enterprises and campuses, public cloud will occupy an important and supreme proportion in their informatization. Due to historical reasons and displays, most of the parks and big brother enterprises have large-scale computer room facilities and equipment. The best solution for such enterprises is still public cloud, but based on reality, public and private hybrid cloud will be the solution in the short term, and the equipment cannot be abandoned, the architecture is not to be changed, open up online and offline, put more flexible content and newly deployed content online, and gradually realize the online business, which will be the trend. But it takes a process.

For government and education enterprises, the public cloud can technically meet the technical needs and solutions of such enterprises. Due to extremely high requirements for data security and some policy reasons, data currently needs to be physically isolated. Some public cloud enterprises also provide independent facilities such as government cloud and financial cloud to meet the needs of government affairs, but some non-core businesses can also be gradually transferred to public clouds.

The above personal opinions, based on simplicity, speed and ease of use as a whole, public cloud is the trend of the times, and it is not possible to completely replace IDC in the short term, so small and medium-sized enterprises can choose with their eyes closed. Pure hand-played, if you need in-depth communication, you can continue**.

The biggest difference between public and private clouds:

Generally speaking, private clouds are more expensive than public clouds;

Data security: Private clouds are built separately and have dedicated resources, so data security is higher than public clouds.

Explanation of terms: public cloud: usually refers to the cloud that can be used by third-party providers for users, and public cloud can generally be used through the Internet, generally speaking, the cost is low or even some freeThe core attribute of the public cloud is the shared resource service

Private cloud: Built for individual use by a single customer user, it provides 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

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.

Little Bird Cloud is an enterprise-level cloud service provider that provides public cloud services!

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.
