Multitenancy: What It Is, Why It’s Important, and Applications

What comes to mind when you hear the word “timeshare”? The word “timeshare” is used in the so-called “normal world” to describe a holiday home or condo that a swindler in a ratty suit tries to sell you time slots for. This sales pitch frequently entails prospective clients attending some ludicrous seminar, receiving a meagre reward for their time and trouble, and learning why it’s a good idea to invest money in a Florida beach house.

Fortunately, this timeshare is not the same as that type. Nobody will try to sell you a reserved spot in a beachside bungalow. In the realm of IT, the term “timeshare” is used to refer to multitenancy, a common feature of cloud computing.

What Is Multitenant Housing?

A type of cloud architecture known as multitenancy allows different clients of the same cloud vendor to share the same computer resources. Each customer is referred to as a renter. Both shared hosting on servers and sharing software resources fall under this category of sharing.

Multiple instances of a given application may run in a shared environment thanks to multitenancy. Consequently, multiple tenants can be served by a single instance of software running on a server. Physical integration between tenants is accompanied by intellectual separation. In a multi-tenant architecture, a software programme with this setup will share dedicated instances of configurations, data, user management, and other attributes.

Tenants can modify the shared resource to some extent, for as by deciding which users can use the resources or how the application functions. They are unable to alter the coding, though.

Here is a typical illustration. Think of your neighbourhood bank. Although several customers deposit their money in the same bank, each has a private account where their assets are kept separate and cannot be accessed by other customers. One bank, many customers, but they can’t talk to each other, can’t use each other’s resources, and aren’t even aware of each other’s existence.

The public cloud model is made up of one infrastructure, numerous servers, and exclusive use and access by each server to its own data and other cloud-based services.

Single-Tenant vs. Multi-Tenant
Unsurprisingly, a single tenant architecture is the antithesis of a multi-tenant architecture. The phrase “single tenant” gives away what it is. Software with single tenancy only serves one customer with the help of the underlying infrastructure. There are no shared databases or software instances; each customer has a unique, independent instance.

The arrangement with a single tenant has benefits of its own. Starting out, a single tenancy provides a more secure environment because each tenant’s resources are completely independent from the resources and information of other tenants. The customer also has total control over modification and functionality. Finally, because resources are plentiful and always available, single tenant clients benefit from higher reliability.

The disadvantages of a single tenancy do exist, though. Since there is no cost- or resource-sharing, a single tenancy is often more expensive. Additionally, single tenants are responsible for all setup and upkeep themselves, which means there is more effort required.

Therefore, single tenancy provides better resource availability and privacy than multitenancy. The latter, however, uses less of the customer’s time, assets, and money.

Multitenancy’s importance
Multitenancy is a crucial idea since it enables us to get the most out of the public cloud environment. In turn, the cloud environment has the data, clients, partners, suppliers, and global resources of everyone. Therefore, multitenancy provides everyone with constant, high-quality cloud access at a reasonable cost. It’s a fantastic approach to level the playing field so that a tiny company may compete more effectively against a massive mega-corporation.

A bigger audience benefits when the cloud host delivers new functionalities, features, and innovations. On a multi-tenant site, the needs of a select few users frequently drive the creation of additional features. Still, eventually, everyone in the architecture ends out the better for it.
