SaaS (Service as a Software)-multi-tenant-oriented multi-layer model and construction method thereof

Abstract

The invention belongs to the field of software technology, and discloses an SaaS (Service as a Software)-multi-tenant-oriented multi-layer model and a construction method thereof. SaaS software is divided into seven different layers in a top-down manner according to an SaaS software maturity degree model and different granularity, and multi-tenant, saleable and configurable characteristics of theSaaS software are reflected. Color sets of colored Petri nets (CPN) can represent different tenant requests, object-oriented Petri reflects encapsulation of services, and is invisible to outsides, andinternal details influence system running. Ideas of the colored Petri nets and object-oriented Petri nets (OOPN) are respectively used for reference to extend the Petri nets, and a CSOP(Colored Service-Oriented Petri Nets) and SOP (Service-Oriented Petri Nets) system is provided. The model provides a formalized tool for modeling of the SaaS software. The formalized model provided by the inventioncan be run in a tool of the colored Petri nets, and thus can simulate running of the SaaS software, and analyze hidden troubles existing in system running.

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
