Cloud computing is a service model, and the overall design is service-oriented.

The virtualization technology refers to the process of creating multiple VMs that share the hardware resources of a physical server.

has two meanings. One is accurate computing units. If a cake is too large for one person, it is better to divide it into small pieces to share. That is, with smaller computing units, IT resources can be fully used. The other meaning is the separation of software and hardware. Before virtualization, software and specified hardware are bound together, and after virtualization, software can be freely migrated on all hardware, which is like renting a house instead of buying one.

Enterprises in the fast-growing ICT industry are posing higher requirements on compute, storage, and networking resources. Within this context, cloud computing, has emerged to meet the need for on-demand resources and accelerate business innovation.

Multiple VMs can run on one physical server, which means that the virtualization layer can allocate the resources of a physical server to multiple VMs. This is called ??

is the main form of cloud computing, which is developing considerably in China. Public cloud vendors can be classified as follows: • Traditional telecom infrastructure carriers, including China Mobile, China Unicom, and China Telecom • Local government cloud computing platforms • Public cloud platforms built by Internet giants, such as Alibaba Cloud and Tencent Cloud • Some IDC carriers, such as 21Vianet Group • Enterprises with foreign technical background or introducing foreign cloud computing technologies, such as Fengqi.Asian Cloud

is a combination of a public cloud and a private cloud or on-premises resources, that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Users can migrate workloads across these cloud environments as needed.

Cloud services are billed based on the actual resource usage, such as the CPU, memory, storage capacity, and bandwidth consumption of cloud servers. Cloud services provide two billing modes: pay-per-use and yearly/monthly.

Customers can deploy processing services based on actual requirements on the server running time, network, and storage, and do not need to communicate with each service provider.

allows file sharing among multiple servers or enterprise departments.

enables access to comprehensive public services through the Internet and serves as an extensive service platform with software, application, and information resources provisioned for governmental bodies.

is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction (National Institute of Standards and Technology (NIST)).

As the broad access mentioned above, IT services can be provided anytime and anywhere. From the perspective of users, cloud computing data centers are geographically distributed and the performance of network bandwidth varies by region. Large public cloud service providers have dozens or even hundreds of data centers or service nodes to provide cloud computing services to global customers.

can also be understood as standardization, which is similar to power utilization. The voltage and socket interface should be the same for various electrical appliances and devices.

Cloud computing service is on a large scale as it centralizes IT resource supply. This makes cloud computing different from conventional IT

provide resource connectivity and isolation, such as data center networks and campus networks. On the cloud, VMs use virtual networks (for example, VPC) that have a logical topology similar to that of traditional networks.

Computing resources of the service provider are centralized so that customers can rent services

Public cloud has a large number of users with different requirements. Therefore, advanced security technologies must be adopted to protect cloud computing.

provide the computing power required for running services such as websites, office software, and data analysis. Currently, typical compute cloud services are VMs and containers.

features a flat, easy scale-out architecture, which is suitable for cloud storage. It is mainly used for massive data storage, cold data backup, and software repository.

VMs exist in the virtualization system as files. You can migrate VMs by cutting/copying and pasting files.

The cloud platform provides infrastructure (such as servers, storage devices, networks, and virtual resources) and application deployment environment (such as the operating system, middleware, and software running environment) and maintains related resources. Users only need to focus on applications and data.

The cloud platform provides all resources, services, and maintenance. Users only need to use applications.

If one VM on a server is faulty or infected with viruses, the other VMs can still run properly.

is provided to meet the market competition and requirements. Cloud computing, with low individual technical skill and financial requirements, makes IT easy to use. Small and micro startups are always willing to enjoy more IT services at the lowest cost. Based on this situation, low-cost software is required to earn money at small profits but quick turnover.

service provider owns and operates the cloud infrastructure and provides cloud services open to the public or enterprise customers. This model gives users access to convenient, on-demand IT services, comparable to how they would access utilities like water and electricity.

After being migrated to another physical server, a VM can properly run without any modification on the server because VM OSs are decoupled from physical hardware.

features high performance and low latency, meeting different high I/O service requirements.

is a cloud infrastructure operated solely for a single organization. All data of the private cloud is kept within the organization's data center. Attempts to access such data will be controlled by ingress firewalls deployed for the data center, offering maximum data protection

The cloud platform provides infrastructure (such as servers, storage devices, networks, and virtual resources) and maintains related resources. Users only need to pay attention to the system and application layers.

means that IT resources can be elastically provided.

Various capabilities can be obtained over the Internet, and the Internet can be accessed in standard mode from various clients, such as mobile phones, laptops, and PADs.

Cloud computing can rapidly and elastically provide computing capabilities. A customer can rent unlimited resources and purchase required resources at any time.
