There are three main types of cloud computing services, what are the functions and service objects o

Platform-as-a-Service（paas）

Platform-as-a-Service is cloud computing for developers. The most important feature of this cloud computing is that it comes with its own development environment and provides developers with development kits.

Software as a Service（saas）

Software as a service is cloud computing that can be perceived by ordinary consumers, and the biggest feature of this cloud computing is that consumers do not buy any physical products, but buy services with the same functions as physical products.

3. Infrastructure-as-a-Service (IaaS).

Infrastructure-as-a-Service is generally geared towards enterprise users, and the biggest feature of this type of cloud computing is that it rents out the computing power and storage power of servers.

The form in which cloud computing is implemented.

Cloud computing is built on advanced internet technology.

On the basis of it, there are many forms of its implementation, which are mainly completed through the following forms:

1) Software as a Service. Usually, the user sends out service requirements, and the cloud system provides resources and programs to the user through the browser. It's worth mentioning that it doesn't cost anything to use a browser app to deliver service information, and the same goes for businesses, as long as the app is good.

maintenance work can be done.

2) Network services. Developers can continuously improve and develop new application products on the basis of APIs, which greatly improves the operational performance of stand-alone programs.

3) Platform services. It generally serves the development environment, assists intermediaries to upgrade and develop programs, and improves the user's best function, and the user can use the Internet to improve the user's best function, which has the characteristics of fast and efficient.

4) Internet integration. When using the Internet to issue instructions, there may be many similar services, and the cloud system will match the appropriate services according to the needs of the end user.

5) Business service platform. The purpose of building a business service platform is to provide a communication platform for users and providers, so that management services and software-as-a-service applications are required.

6) Managed Service Providers. This application model is not new and often serves the IT industry.

Common services include scanning email viruses and monitoring application environments.

According to the type of service, cloud computing can be divided into three categories: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS).

IaaS: Infrastructure as a Service.

Consumers can access services from a well-developed computer infrastructure through the Internet. IaaS is a business model that allocates hardware resources such as data centers and infrastructure to users through the web.

PaaS actually refers to the platform of software development as a service and submits it to users in the form of SaaS. Therefore, PaaS is also a SaaS model.

an application.

SaaS: Software as a Service.

It is a model of providing software over the Internet, and users do not need to buy software, but rent web-based software from a provider to manage business activities.

What are the three types of cloud computing services, namely: IaaS, PaaS and SaaS. Software-as-a-Service) refers to a new form of software service that users can obtain.

It does not require users to install the software product on their own computers or servers, but directly obtains the services they need with the corresponding software functions from a specialized provider through the network according to a certain service level agreement (SLA). Platform as a Service) PaaS (Platform as a Service) refers to the provision of a complete computer platform, including application design, application development, application testing and application hosting, as a service. Infrastructure-as-a-Service (IaaS) refers to the use of cloud computing technology by enterprises or individuals to remotely access computing resources, including computing, storage, and related functions provided by application virtualization technology.

The service model of cloud computing is divided into IaaS, PaaS, and SaaS. Each of these three modes represents three different levels.

SaaS provides software for enterprise or individual end users in the form of network rental, including management applications, business applications, industry applications, and other SaaS applications, which can be invoked by the PaaS layer capabilities, or can be independently developed using LaaS layer resources.

PaaS is for developers, providing a flat environment for software to run or be called by customer applications in the form of APIs and SDKs, including: data analysis, artificial intelligence docker; Push, communication, voice recognition, image recognition, statistics, advertising, etc.

For enterprises or developers, it provides basic resource support, including computing, storage, and networking.

If you want to find a cost-effective and secure cloud service provider, I recommend you to check out Speed Cloud, which is a full-stack cloud-native technology service provider that provides cloud-native applications and data platform products, including container cloud PaaS, DevOps, microservice governance, service mesh, API gateway, etc. You can go and experience it.

The three types of services provided by cloud computing are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS).

Infrastructure-as-a-Service (IaaS), where "infrastructure" refers to "services", is a kind of computing resources that provide virtualization for cloud computing providers, such as virtual machines, storage, networks, and operating systems. Platform-as-a-Service (PaaS) refers to providing a platform for developers to build relevant applications and services on the global Internet.

Software as a Service (SaaS), cloud computing providers can host and manage a variety of application software, software as a service means that software developers and operators can provide customers with on-demand payment software use rights through cloud computing. In fact, in addition to the above three types of services that are recognized by everyone, in fact, cloud computing has many functions, such as Internet integration, management service providers, etc., and each user has his own different feelings.

Introduction to Cloud Computing:

Cloud computing is a distributed computing technology that can decompose a huge amount of data processing processors through the "cloud", and then a system composed of multiple servers can process them. Cloud computing, also known as grid computing, can process tens of thousands of data in a very short period of time.

Cloud computing is not a new network technology, it is just a new network application concept. The core of cloud computing is to provide fast and secure computing and data storage services on the network with the network as the center. Cloud computing is also a convenient and on-demand way to access configurable computing resources (including networks, servers, storage, application software, etc.), and only a small amount of management and maintenance can realize the needs of data computing.

The basic types of services for cloud computing are as follows:

1、saas

SaaS refers to a new form of software service that does not require users to install the software product on their own computer or server. Instead, they get the quietly reputed, software-enabled services they need directly from a dedicated provider through the network according to a certain service level agreement.

2、paas

PaaS refers to the provision of a complete computer platform, including application design, application development, application testing, and application hosting, as a service. In this service model, customers do not need to purchase hardware and software, but only need to leverage 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 decomposition of huge data computing and processing programs into countless small programs through the network cloud. Then, through a system composed of multiple servers, these applets are processed and analyzed, and the results are returned to the user. In the early days of cloud computing, to put it simply, it was simple distributed computing, which solved the task distribution and merged the calculation results.

With this technology, tens of thousands of pieces of data can be processed in a very short time, resulting in a powerful network service. At this stage, cloud services are not just a kind of distributed or limb computing, but the result of the evolution and leap of computer technologies such as distributed computing, utility computing, load balancing, parallel computing, network storage, hot backup redundancy, and virtualization.

The basic types of services for cloud computing include: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).

Computing services, i.e., cloud services. The definition of China's cloud computing service network is: refers to cloud computing products that can be used as services.

Including cloud hosts, cloud space, cloud development, cloud testing, and comprehensive products. Users get the resources and services they need on demand and easily scalable through the network.

As we all know, for the type of cloud computing services, it can generally be divided into three levels, namely: IaaS, PaaS and SaaS. These three levels constitute the overall architecture of cloud computing technology, which may include some virtualization technologies and applications, automated deployment, distributed computing and other technologies, the advantage of this technical architecture is that it can show very excellent parallel computing capabilities to the outside world to flush the dust and large-scale scalability and flexibility.

Service Method:

Cloud service providers, for small and medium-sized enterprises to build all the network infrastructure and software, hardware operation and judgment platform, and responsible for all the early implementation, later maintenance and a series of services, enterprises do not need to purchase software and hardware, build computer rooms, recruit IT personnel, only need to pay a one-time project implementation fee and regular software leasing service fees in the early stage, you can enjoy the information system through the Internet Henghao network.

Service providers can guarantee the security and confidentiality of each enterprise's data through effective technical measures. The effect of the cloud service model adopted by the enterprise is basically the same as that of the enterprise's self-built information system, but it saves a lot of money for the purchase of IT products, technology and maintenance operation, and the information system is conveniently used like turning on the tap to use water, thereby greatly reducing the threshold and risk of informatization of small and medium-sized enterprises.
