Five Features of Cloud Computing

Hi, everyone!

In recent years, cloud computing has permeated every aspect of our lives, but what is cloud computing? What are the characteristics of cloud computing?

What is cloud computing?

A model that provides on-demand self-service and provides network access for scalable, elastic, and shared physical and virtual resource pools. Currently, cloud computing is based on centralized resource management and control. All software and hardware resources are managed, scheduled, and sold as unified resources.

Five Features of Cloud Computing

Anytime access

The network provides many available functions that can be accessed from different terminals through various unified standard mechanisms.

Self-service

Consumers can deploy resources unilaterally without interacting with cloud service providers.

Resource sharing

Resource pooling: Physical resources are decoupled from logical resources through virtualization to implement resource pooling of computing, storage, and network resources. From the perspective of users, they do not need to care about the device model, complex internal structure, implementation method, and geographical location. They only need to care about the services they need. From the perspective of resource managers, the resource pool with the greatest benefits can be added, deleted, and replaced. In addition, it is convenient to manage and schedule resources.

Elastic scaling

Resource pool resources are much larger than those required by a single user or customer. Therefore, the resource pool appears to be infinite. Once again, resources can be rapidly deployed and released, sometimes automated, to allow rapid scaling up and downsizing.

Service measurable

Provides measurable capabilities for abstract use of resources.

Four Deployment Modes of Cloud Computing

1. Private cloud: Cloud resources can be used only by users in one organization, which is the core feature of the private cloud. However, there is no strict regulation on the ownership, schedule management, and operation of the cloud. The ownership, schedule management, and operation of the cloud may be the company, a third-party organization, or a combination of the two. The cloud may be located within the organization or hosted elsewhere.

2. Community cloud: Cloud resources are dedicated to users in several fixed units, which have the same requirements on the cloud (such as security requirements, cloud mission, rules, and compliance requirements). The ownership and routine management of the cloud may be one or more units in the community, it could be a third party outside the community, or a combination of the two. The cloud may be deployed locally or elsewhere.

3. Public cloud: Develop cloud resources for public use. The ownership, day-to-day management and operation of the cloud can be a business organization, academic institution, government department, or a combination of them. The cloud may be deployed locally or in other places. For example, the cloud of the Zhongshan public cloud may be deployed in Zhongshan or Shenzhen.

4. Hybrid cloud: A hybrid cloud consists of two or more different types of clouds (private, community, and public) that are independent, but combine them with standard or proprietary technologies that enable smooth data and application flow between clouds. A hybrid cloud consists of multiple clouds of the same type. The hybrid cloud consisting of private and public clouds is the most popular one. When the demand for private cloud resources is too high for a short period (called cloud bursting), public cloud resources are automatically rented to suppress the peak demand for private cloud resources. For example, online stores have a huge number of clicks during holidays, which will temporarily use public cloud resources for emergency purposes.

Three Service Modes of Cloud Computing

Software as a Service (SaaS). Cloud service providers lease the application software layer of the IT system as a service. Consumers can directly use the application software without installing the application software themselves, which further lowers the technical threshold for cloud service consumers.

Platform as a Service (PaaS). Cloud service providers lease the platform software layer of the IT system as a service. Consumers develop or install programs and run programs.

Infrastructure as a Service (IaaS). Cloud service providers lease the infrastructure layer of the IT system as a service, and consumers install operating systems, middleware, databases, and applications by themselves.
