Software as a service (SAAS) is increasingly becoming the choice of many small and medium-sized enterprises to reduce costs and achieve informatization. The core technology in SAAS is the multi-tenant technology.
The multi-tenant technology provides the following methods:
Method 1: All tenants share a single application instance, that is, the same server, middleware, and application.
Method 5: The Tenant runs its own application instance on a separate server (currently many application service providers [Asp] use this method ).
There are at least three main methods between these two methods, which have different resource sharing degrees and development complexity. Each method provides different benefits (in terms of scalability and operational efficiency) at different costs (in terms of development complexity and market time ).
Among these methods, method 1 has the highest degree of sharing and the lowest cost, but must be supported by the program.
The 3-5 method is costly, but does not require any program changes.
Definition of Multi-tenant on Wiki:
MultitenancyRefers to a principle in Software Architecture where a single instance of the software runs on a software-as-a-service (SAAS) Vendor's servers, serving multiple client organizations (tenants ). multitenancy is contrasted with a multi-instance architecture where separate software instances (or hardware systems) are set up for different client organizations. with a multitenant architecture, a software application is designed to virtually partition its data and configuration so that each client organization works with a Customized Virtual application instance.
