Multi tenant SaaS architecture is becoming more and more popular among Software-as-a-Service (SaaS) vendors. This is because; in a multi tenant environment, clients together with the users share a common service which is provided by one single technology platform. This enables them – clients and users, to share components available in the stack’ including the servers, database layers, and data model.

Multi tenancy architecture simply involves a single instance serving multiple customers. Tenants may also be given the opportunity to customize some features such as color, or business rules, but changing the application codes is impossible if you are not an administrator. This approach is pocket friendly because almost, if not everything, is shared; these include the software development plus maintenance costs.

Multi tenant SaaS architecture is a solution that provides:

Single instance Multi-tenant

This feature enables a single installation that comprises multiple portals together with private data storage. SaaS software supports a number of portals and websites using a single portal database. The application installed in a server has the capacity to support different websites from one hosting account. This is ideal when you are dealing with sub-hosting services for organizations, or memberships.

Billing and Usage Metering

SaaS technology allows components like portals and APIs to link your app repeatedly into usage metering services’ which are normally coupled to billing capacities. Having a record on how your app is doing is critical, since it determines the cost of the software product. When you have factored the amount, you’ll need a great mechanism to collect the money; either by bank account transfer, credit card, or even traditional check. Software-as-a-Service is the best approach to get the job done.

Access Control Framework

Multi tenant SaaS architecture allows admin members to define and also assign roles as well as permission for certain groups like administrators, subscribers, affiliates, media, users, and content providers. The have the ability to grant access to edit for specific number of people. The admin can also assign rights to either a module on a page, a page, or the entire site, and each user can belong in more than a single group.

GUI Configuration & product Management Control

Multi-tenancy offers a friendly user interface to help manage GUI application configuration and also control your software instance. The architecture has a modular method where the user can update or add modules. This assists experts such as system administrators and integrators to analyze and manage their SaaS components within minutes.

Operating as a SaaS provider means that you are shifting from a packaged application model – product organization, to a hassle-free management known as service organization. Product organization deals with scalability and competence but service organization contains basic workflows such as customer provisioning and billing which have to be altered unless they are executed.

From a vendor’s point of view, multi-tenancy is sharing of an app instance by several clients with their own individual view which results to increased efficiency. Multi tenant SaaS architecture is a style that influences sharing including economies of scale to ensure that the result is a cost-efficient hosting solution for your software product.
