Multitenant technology is defined from the naming itself as multiple tenants which is coined as multitenant. This is been build in order to make multiple users or tenants to use an application with same logic, functionality simultaneously is called as multitenant application. Every tenant will have their own view point on the applications like its use, administration and customization. Here the major feature here is tenants will not be able to access which is not theirs.

Here tenants are given various rights to edit themselves and some of the features are:
- Business process
- Data model
- Access control
- User Interface
The multitenant architecture is really more complex than the single tenant architecture where the applications, data schemas, databases, middle wares all are been shared with each other. The security used up here is like security on the whole for a single tenant architecture.
Multitenant Architecture Features:
- Data security – There is a high data security where tenants cannot access other tenants data.
- Application Upgradation – The application upgradation is automatically, simultaneously done thought-out the applications at a time without any loss of data's or functionality.
- Scalability - It scaling performance increases accordingly with the existing tenants as well as increasing the number of tenants.
- Usage isolation – The usage of one tenant will not affect the functionality and other features of other tenants.
- Recovery – Each tenant data's and other details are been taken backup every time, when there is any disaster this safety measure will be in form.
- Cost – Tenants are only billed only for which they have consumed for usage and not for all the tenants or any divided costs.
- Performance tuning is very easy over here.
Multitenant applications are expected to provide a very good wide range of security isolation, robustness and performance between multiple tenants which is provided by the layers below the application in case of applications with multiple-instance.
