White Paper: SAAS has four typical application models

According to the analysis in the White Paper, according to the typical application of the current SaaS model, there are four typical modes from the operational perspective based on the different control strength of SAAS applications:

　　(1) "Store" mode (closed and full control mode)

　
In the "specialty store" mode, the software service operation support platform provides full control of the software service operation stage. The running of software applications is fully managed on the platform. The hosting methods can be divided into open hosting and proprietary
Hosting method. Open hosting means that the Operation Support Platform can run on the Internet, and users can access it through the external network of the enterprise. Private hosting refers to the operation support platform running in the private network of the enterprise.
Medium, external networks cannot be accessed, which is usually for security reasons. In addition, this software service operation support platform does not provide external interfaces, and third parties cannot use the functions and data of the support platform for development.
Value-added applications.

The advantage of this mode is that you do not need to operate and maintain applications. Because the applications are fully controlled by the platform, you can optimize the configuration and management of resources.

　　(2) "Intermediary store" mode (open, access and management control mode)

　
In this mode, the software service operation support platform does not support the actual operation of applications, but provides some basic functions such as network application access, user information management, and billing. These functions are operated through software services
Third parties can use the open interfaces provided by the platform to develop functions to construct more software applications and connect them to the platform, you can also pay for the use of network applications.

The advantage of this model is that users can quickly enter the software service field based on their inherent brands without the need for O & M applications, and lead more software providers with independent operation capabilities to enter the service market.

　　(3) "Supermarket" mode (open and full control mode)

　
In this mode, the software service operation support platform is open to the outside, and some basic services and business services are provided through the application development interface, this allows third parties to develop and apply plug-ins within a certain scope.
Customization and service integration. In this mode, the platform has full control over the application. Therefore, this method has high requirements on the Multi-tenant, configurable, scalable, availability, and reliability of the platform.

　　(4) "mall" mode (open and non-full control mode)

　
In this mode, the software service operation support platform is open to the outside world. Third parties can use the basic services provided by the platform to develop new networked applications. Software Service Operation Support level different from the "full control" Mode
In this mode, although the platform controls the operation and partial management of networked applications, it cannot completely control the management of networked applications, but gives the third-party developers greater control. For example, they can
To control the naming, price, user permissions, and access rules of networked applications.

In this mode, the Operation Support Platform also provides basic services, application development environments, and many guaranteed functions. This mode requires a high degree of versatility for the platform and a high requirement on the virtualization capability of storage and computing resources.
