The cloud service type is "Software as a Service". Software as a Service (SaaS) is a model that provides software through the Internet. Users do not need to purchase software, but rent Web-based software from providers to manage business activities. SaaS service providers uniformly deploy application software on their own servers. Users order application software services from manufacturers through the Internet based on their needs. The service provider charges based on the quantity of software ordered by the customer, the length of time and other factors, and charges the customer through the browser. Provides software patterns.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The type of cloud service that provides users with software services based on on-demand rental is "software as a service".
Cloud computing service, that is, cloud service. 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.
For cloud computing service types, they can generally be divided into three levels: IaaS, PaaS and SaaS. These three levels form 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 perform very well externally. Parallel computing capabilities, large-scale scalability and flexibility.
Three types of cloud services
Infrastructure as a Service (IaaS)
IaaS Contains the basic building blocks of cloud IT. It typically provides access to network functions, computers (virtual or dedicated hardware), and data storage spaces. IaaS provides you with the highest level of flexibility and administrative control over your IT resources. It is most similar to existing IT resources that many IT departments and developers are familiar with.
Platform as a Service (PaaS)
PaaS allows you to focus more on applications without having to manage the underlying infrastructure (usually hardware and operating systems) Deployment and management of programs. This helps increase efficiency because you don't have to worry about resource acquisition, capacity planning, software maintenance, patch installation, or any of the undifferentiated heavy lifting associated with running your application.
Software as a Service (SaaS)
It is a model that provides software through the Internet. Users do not need to purchase software, but rent web-based software from providers. , to manage business activities.
SaaS provides a complete product that is run and managed by the service provider. In most cases, what people mean by SaaS is end-user applications (such as web-based email). With SaaS products, you don’t have to think about how to maintain services or manage infrastructure. You just need to think about how to use that particular software.
SaaS service providers uniformly deploy application software on their own servers. Users order application software services from manufacturers through the Internet based on their needs. The service provider charges based on the quantity of software ordered by the customer, the length of time and other factors. And the mode of providing software to customers through browsers. The advantage of this service model is that the service provider maintains and manages the software and provides hardware facilities for running the software. Users only need to have a terminal that can access the Internet to use the software anytime and anywhere.
Under this model, customers no longer spend a lot of money on hardware, software, and maintenance personnel like the traditional model. They only need to pay a certain rental service fee and can enjoy the corresponding hardware and software through the Internet. and maintenance services, which is the most efficient operating model for network applications. Salesforce.com and Google Apps both fall into this category.
The SaaS model greatly reduces the cost of using software, especially large-scale software, and because the software is hosted on the service provider's server, it reduces the customer's management and maintenance costs and has higher reliability.
