A multi-layer model for saas multi-tenancy and its construction method

Abstract

The invention belongs to the technical field of software, and discloses a multi-layer SaaS multi-tenant-oriented model and a construction method thereof. According to the SaaS software maturity model, the SaaS software is divided into seven different levels from top to bottom according to different granularities. It reflects the multi-tenant, scalable, and configurable characteristics of SaaS software; the color set of the colored Petri net can represent the requests of different tenants, and the object-oriented Petri reflects the encapsulation of the service, which is invisible to the outside world, and internal details affect the system operation. Using the ideas of colored Petri nets and object-oriented Petri nets respectively, the Petri nets are extended, and CSOP and SOP net systems are proposed. The invention provides a formalized tool for the modeling of SaaS software; the formalized model proposed by the invention can run in the colored Petri net tool, so that the operation of the SaaS software can be simulated, and hidden dangers existing in system operation can be analyzed.

Description

technical field [0001] The invention belongs to the technical field of software, and in particular relates to a SaaS multi-tenant-oriented multi-layer model and a construction method thereof. Background technique [0002] SaaS is a new software model that has emerged in recent years, and it is the abbreviation of Software as a Service (Service as a Software). It is very different from the traditional software model. The SaaS model means that the software service provider provides network-based software services and is fully responsible for maintaining the background work such as the software and hardware platforms required by the software service. to use these services. When it comes to SaaS, people will think of cloud computing (Cloud Computing). Cloud computing divides the services provided into three levels: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS. The SaaS we often refer to is actually SaaS in cloud computing. As the most successful...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the problems existing in the existing technology are: traditional software has poor scalability, does not have a multi-tenant architecture, and has low configurability; while the SaaS software maturity model is an important standard in the SaaS software industry. The specification to be followed, the existing technology does not support this model, and does not reflect the characteristics of SaaS multi-tenant, scalability, and configurability; especially the complex architecture and operation of SaaS software, which makes traditional methods face huge challenges; the SaaS The software is described as a single-layer service composition relationship. To describe and analyze it with the basic Petri net, there will be problems such as state space explosion, and the relationship between multi-tenants cannot be reflected
