6 Tenancy
6.1 About multitenancy
The service we provide to you uses a multitenancy model. Multitenancy is the norm for Software as a Service (SaaS) solutions and is the model used by all major SaaS solutions, such as SalesForce or Google Apps – and also your bank.
Your bank does not have a separate system for you as a customer, instead your bank uses multitenancy, which means that a set of pooled computing resources is shared among multiple customers (tenants) using application level isolation. A tenant (e.g. your company as a customer in your bank) is a group of users who share a common access with specific privileges to the software instance.
With a multitenant architecture, the software application is designed to provide every tenant a dedicated share of the instance - including its data, configuration, user management and individual functionality.
Please refer to the Microsoft tenancy design pattern page for a deeper explanation of SaaS and Multitenancy.
