## **What is Multitenancy?**
Multitenancy is a software architecture concept that enables a single application instance to serve multiple consumers or tenants simultaneously. In a multitenant environment, each tenant operates independently, with its data, configurations, and customizations, while sharing the same underlying infrastructure and application codebase. This approach enables efficient resource utilization and cost savings by consolidating multiple users onto a shared platform. Multitenancy is commonly used in cloud computing, SaaS (Software as a Service) applications, and enterprise systems, providing scalability, flexibility, and security for hosting multiple clients or organizations within a single software instance.

## **Types of Multitenancy**

There are generally three types of multitenancy:

**● Shared Database Multitenancy:** In this approach, multiple tenants share a single database, each with their own set of tables or schema within that database. Data is segregated at the table or schema level, ensuring tenant data isolation.

**● Shared Instance Multitenancy:** With shared instance multitenancy, multiple tenants share a single instance of the application, where the application logic and codebase are shared among all tenants. Each tenant has its isolated data and configurations within the shared model.

**● Virtualized Multitenancy:** Virtualized multitenancy involves running separate instances or virtual machines of the application for each tenant, providing complete isolation between tenants. Each tenant has dedicated resources, including databases, servers, and application instances. 

## **Benefits of Multitenancy Architecture**
Multitenancy architecture offers several benefits. Some of them are mentioned below:

**● Efficient Resource Utilization:** Multitenancy allows for optimal use of resources by sharing infrastructure, application code, and maintenance efforts among multiple tenants. This leads to cost savings and improved scalability as resources are efficiently utilized across the tenant base.

**● Cost-Effectiveness:** With multitenancy, the cost of infrastructure, maintenance, and upgrades can be shared among multiple tenants. This reduces the overall cost per tenant, making it an economical solution for both service providers and tenants.

**● Scalability and Flexibility:** Multitenant architectures are designed to scale easily as new tenants are added. They provide flexibility in terms of adding or removing tenants, accommodating varying workload demands, and adapting to changing business needs.

**● Simplified Deployment:** Multitenancy simplifies the deployment process since a single application instance can serve multiple tenants. This reduces deployment complexities and minimizes the time and effort required to set up new models for each tenant.

**● Rapid Onboarding:** Multitenant architectures facilitate quick onboarding of new tenants. The shared infrastructure and standardized deployment processes allow efficient provisioning and configuration of new tenant environments.

**● Streamlined Maintenance:** By consolidating multiple tenants onto a shared platform, maintenance tasks such as upgrades, patches, and bug fixes can be performed more efficiently. This eliminates the need for individual updates for each tenant, reducing maintenance efforts and ensuring consistency across the tenant base.
