Many beginners are not very clear about what public cloud, public cloud and hybrid cloud are. In order to help you solve this problem, the editor below will explain it in detail. People with this need can come and learn. I hope you can learn something.

What is public cloud?

The 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 are provided through Internet. In the public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. In the public cloud, you share the same hardware, storage, and network devices with other organizations or cloud "tenants". You can use a Web browser to access services and manage accounts. Public cloud deployments are typically used to provide Web-based email, web-based office applications, storage, and test and development environments.

Advantages of public cloud:

Lower cost-there is no need to buy hardware or software, only pay for the services used.

No maintenance required-maintenance is provided by the service provider.

Almost unlimited scalability-provides on-demand resources to meet business needs.

High reliability-with a large number of servers to ensure protection from failures.

What is a private cloud?

A 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 hosted by a third-party service provider. However, in the private cloud, services and infrastructure are always maintained on the private network, and the hardware and software are dedicated to the organization. In this way, the private cloud makes it easier for organizations to customize resources to meet specific IT needs. Private clouds are typically used by government agencies, financial institutions, and other medium-to large-sized organizations with business-critical operations that want more control over the environment.

Private Cloud benefits:

More flexible-organizations can customize the cloud environment to meet specific business needs.

Higher security-resources are not shared with other organizations, resulting in a higher level of control and security.

More scalable-private clouds still have the same scalability and efficiency as public clouds.

What is a hybrid cloud?

Hybrid clouds are often considered to have the best of both worlds, combining local infrastructure or private and public clouds, and organizations can take advantage of both. For example, the cloud butler hybrid cloud management platform not only supports mainstream public cloud vendors in the industry, such as Aliyun, Tencent Cloud, Huawei Cloud, JD.com Cloud, Ucloud, Baidu Cloud, AWS, Azure (China only), Qingyun, etc., but also connects internal private clouds (such as openstack) to the cloud to easily complete hybrid cloud management. In hybrid clouds, data and applications can move between private and public clouds, providing more flexibility and deployment options.

Hybrid Cloud benefits:

Controllable-organizations can maintain a private infrastructure for sensitive assets.

Flexibility-other resources in the public cloud can be utilized when needed.

Cost-effective-has the ability to scale to the public cloud, so additional computing power can be paid only when needed.

Easy-it takes no time and effort to switch to the cloud because it can be gradually migrated by workload over time.
