Why Consider a Multi-Tenant Architecture?

What is Multitenancy? This is deployment of a multi tenant software architecture whereby a single instance of a program runs on a server and serves several users. Such systems are referred to as "shared". A software application with a multitenant architecture is meant to give each tenant a devoted share of the instance, including its data, user management, configuration, tenant particular non-functionality, and functional features. Multitenancy is a key element of cloud computing.

 A tenant can be a single user, but it is more commonly a collection of people using it, such as a client organization who shares the same access to and opportunities within the application instance. The data of each tenant is segregated from and invisible to the other tenants that share the application.

Multi-tenancy may also apply to cloud hosting services, which might be misleading. A virtual machine (VM) or single physical computer is shared among numerous users or client companies in multi-tenant hosting, also known as shared hosting. Cloud service providers often provide multi-tenant hosting solutions as a low-cost option to dedicated hosting or single-tenant solutions.

Benefits of Multitenant Architecture

Multi-tenant architecture provides significant benefits to both software vendors and users as compared to single-tenant design, which gives each tenant with their own version of the database, application, and accompanying hardware infrastructure.

Lower ongoing costs                     

Ongoing expenses are cheaper than in a single-tenant arrangement since the multi-tenant software provider may serve several customers with only one app instance and accompanying equipment, and the users share the cost of infrastructure, software maintenance, and data center management..

Scalability

With multi-tenant architecture, users are able to expand their business to match the demand of clients, which means that new users can use the same instance of the program at an additional subscription cost.

Coding-free customization

SaaS multi-tenant products are highly flexible, each tenant client can customize the application to their exact business needs without incurring the expenses, effort, and risks of bespoke development.

Regular, constant upgrades and maintenance

Updates and patches are the responsibility of the multi-tenant software vendor. New features are introduced and corrections are implemented without the customer's involvement unlike in single-tenant architecture, where the provider must update every instance of the software.

Enhanced tenant productivity

Tenants are free to focus on more vital duties since they do not have to handle infrastructure or software.

Multi-tenant Cloud

For the longest time now, the term multi tenant cloud was has been used interchangeably with shared hosting and/or any architecture in which clients share computer resources in a private or public cloud. Today, most leading cloud service providers present the majority of their offerings via the multi-tenant model, which enables vendors to maximize the use of their data center hardware and infrastructure and, as a result, offer cloud services to customers at the most affordable cost.

Multi-Tenant Database

When selecting a database for multi-tenant applications, designers must balance the necessity or desire of customers for data isolation and the need for a solution that expands rapidly and economically in response to growth or surges in application traffic.

To achieve total isolation, the developer can designate a different database instance for each client or have all users utilize a single database instance to ensure maximum scalability. However, most developers choose to utilize a data store, which allows each tenant to have its own schema within the same database instance. This is known as soft isolation.
