云计算的基本服务包括(云计算服务的几种形式)

The basic service types of cloud computing are as follows:

1. SaaS

SaaS refers to user acquisition A new form of software service that does not require users to install software products on their own computers or servers. Instead, they obtain the services they need with corresponding software functions directly from specialized providers through the Internet according to a certain service level agreement.

2. PaaS

PaaS refers to providing a complete computer platform, including application design, application development, application testing and application hosting, as a service to customers. In this service model, customers do not need to purchase hardware and software, but only need to use the PaaS platform to create, test and deploy applications and services.

Introduction to cloud computing:

Cloud computing is a type of distributed computing, which refers to the calculation of huge data through the network cloud. The handler is broken down into numerous small programs. Then, these small programs are processed and analyzed through a system composed of multiple servers to obtain the results and return them to the user. In the early days of cloud computing, to put it simply, it was simple distributed computing, solving task distribution and merging calculation results.

Through this technology, tens of thousands of data can be processed in a short time, thereby achieving powerful network services. The cloud service mentioned at this stage is no longer just a kind of distributed computing, but the result of the mixed evolution and leap of computer technologies such as distributed computing, utility computing, load balancing, parallel computing, network storage, hot backup redundancy and virtualization. .

Platform as a Service (PaaS) Platform as a Service is cloud computing for developers. The biggest feature of this kind of cloud computing is that it comes with its own development environment and provides developers with development tool kits.
Infrastructure as a Service (IaaS) Infrastructure as a Service is one of the major service categories that provides virtualized computing resources, such as virtual machines, storage, networks, and operating systems, to individuals or organizations at cloud computing providers.
Computing services are cloud services. The definition of China Cloud Computing Service Network is: refers to cloud computing products that can be used as services. Including cloud hosting, cloud space, cloud development, cloud testing and comprehensive products, etc. Users can obtain required resources and services through the network in an on-demand and easily scalable manner.
The main service forms of cloud computing are Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). There are clear differences in what the three can offer enterprises in terms of storage and resource pools, but they can also interact with each other to form a comprehensive cloud computing model.

According to the development of cloud computing, the current services provided by cloud computing mainly include the following:< /p>

1. Infrastructure as a Service (IaaS): IaaS is the most basic layer of services in cloud computing. It provides virtual computing resources (such as virtual servers, storage space and network connections). etc.), users can use these resources on demand.

2. Platform as a Service (PaaS): PaaS provides higher-level services on top of IaaS. It provides users with a way to develop and run applications. Program platform. Users can use the development tools and application programming interfaces (APIs) provided by the cloud platform to create and deploy their own applications.

3. Software as a Service (SaaS): SaaS is the highest level of cloud computing service. It provides an on-demand subscription software application. Users only need to access these applications through the Internet without having to install and maintain their own software environment.
