What is Multi-Tenant Architecture or Multitenancy?

Multitenancy or Multi-Tenant Architecture is when different cloud users are accessing the same computing resources. It is when several separate companies storing data on the same physical server.

Even though different companies share resources, each of them isn’t aware of the other one, and the data of each of the companies are kept separate. Here, each client/organization is called a tenant. Each of them has its evident independent application and is not aware of the other tenants. The occupant has the freedom to configure their interface, users and classes, etc. Usually, each tenant has these characteristics:

1. View: Tenants should describe the overall design of their application.

2. Business rules: Tenants can define their very own business rules and application logic.

3. Database schema: Tenant can identify an application’s own (real or apparent) database schema. They can insert or delete database tables, rename database fields, etc.

4. Users and groups: Tenants may define their own rules to regulate access to data.

What are the benefits of Multi-Tenancy?

1. Better usage of the resources — One machine reserved for one client is not practical since one tenant cannot use all the device’s processing resources. By sharing machines with multiple tenants, the utilization of available resources is maximized.

2. Lower Costs — With many users sharing resources, cloud vendors may sell their services to more customers at a significantly cheaper cost than if each user needs their dedicated infrastructure.

3. The architecture is easily scalable and offers you pay-as-you-go pricing models.

What are the Drawbacks of Multi-Tenancy?

1. Multi-tenant applications tend to be less stable than apps in other tenant architectures, such as single-tenant apps.

2. In general, multi-tenancy is more complicated than single-tenancy.

3. Multi-tenant systems require tighter security authentication and access controls.

4. Tenants need to think about noisy neighbors, meaning someone else on the same CPU who consumes many cycles, which may slow down the response time.

Types of Multi-Tenancy

1. Multi-tenancy with a single multi-tenant database

This tenancy uses a single instance program and a single instance database to host the tenants and store/retrieve the data. This architecture is hugely scalable, and the database is quickly scaled up for additional data storage as more tenants are installed.

The design is low-cost due to pooled capital. Operational complexity is high, particularly during the design and implementation of applications.

2. Multi-tenancy with one database per tenant

This tenancy scheme uses a single instance program of separate databases for each tenant. In comparison, this architecture has a higher cost and more overheads for each database. It is a beneficial architecture as details from different tenants need to be handled differently — as if they were to go through various regional regulations.

We can boost this design’s scalability by introducing more database nodes, but it relies on the workload. The operational complexity is low due to the use of discrete databases.

3. Single-tenant app with single-tenant database

In this architecture, you install the whole program separately for each user. Each tenant has its instance of the app as well as the database instance. This structure offers the highest degree of data isolation. The cost of this design is expensive due to stand-alone software and databases.

This system is incredibly complex in management and maintenance, but the tenants can be separated by the criteria selected.
