The advent of the second decade of the 21st century has seen businesses leaning towards coworking spaces. Operating in space shared by professionals who help each other grow seems to be a beneficial idea. What is more, it is quite logical from the financial point of view, as it is lighter on one’s pocket. Renting a hot desk for a needed amount of time, instead of paying a monthly rate for a full-fledged office is way cheaper and efficient in terms of economized time and resources. While the tech, financial, and real estate industries are nowadays tightly intervened, it didn’t take long before the concept of sharing the space has infiltrated the IT-market. Nonetheless, developers know it by the name multitenancy, which is quite an interesting concept to discuss, especially if your company tends to provide similar software development and support services to a range of customers. Before we plunge ourselves into the whirl of technicalities, let us first define what the concept of multitenancy actually is. Multitenancy is an architectural approach that lets multiple independent instances of copious or single applications operate jointly in a shared environment. Sounds a bit of rocket science, right? Yet, multitenancy is nothing to be afraid of even if you hear the term for the first time. Long story short, multitenancy is an approach that lets you build an app to be used by copious customers at the same time. Nonetheless, while multitenancy is built on the principle of using a common database, each of your customers can have their own secure database that does not intervene with the other cloud repositories within the same space. It all depends on the variant of a multitenant architecture that they would like to have in the product. Multitenancy is quite a bilateral concept that gets both positive and negative reviews from developers. So, let’s shed the light of truth on what a multitenant approach in app development is and what are the best situations to use it. 

Is It That Good?
Before we take to discussing the modes and ways of using multitenancy, let us first deal with the probable counter-arguments that might be coming from the folks that disapprove of its usage. Copious developers still doubt the efficiency of a multitenant approach, claiming that it might add noise and complexity to the development process. While the multitenant instances are becoming more and more omnipresent within the modern applications’ stack, a multi-cloud strategy, which is the core of the multitenancy approach, represents an unprecedented challenge to legacy analytics. Imagine your company taking over a development project that requires a couple of new instances added. The critics claim that you will have to face an immense tech debt that will surely make your project stagger along the way. Instead of working on the features required, you will have to deal with a lot of research pertaining to the platform's stack. Thus, a developer will require an enhanced intelligence strategy in order to deal with the data consolidated within the single pane created throughout developing a multitenant app. Still, it should be acknowledged that the majority of multitenant apps are built from scratch, which means that the so-called noise and complexity are not that much of a problem.Django (Un)Chained?
Django framework, which is the core platform for developing multitenant apps, is also being harshly criticized by today’s critics for being too slow. This Python-based open-source web framework is known as being a widely used 501 non-profit module that is built on the model-template-view architecture pattern. Nonetheless, it lacks convention, when compared to, for example, Ruby on Rails. As a result, the configuration panel is too extensive and ends up slowing the development process down. Django is also not the best choice for you if you are looking to develop a lot of small projects hosted on a multitenant cloud. It might be too complicated for developing copious and simplistic projects, given the expansive toolkit it features. However, analyzing an app’s legacy and tech debt is a hard task regardless of the web framework used. Therefore, claiming that opting for a multitenant approach might be a mistake because of the noise and complexity seems to be quite a vague statement. What is more, the Python ecosystem depends heavily on the internal configurations, so it does not matter whether you use Django. Even though Django might seem too monolithic and requires a developer’s comprehensive knowledge of the system, it is easy to integrate with another Django app, and it offers a lot of routes to follow when developing a multitenant application. There are multiple schemas to use when building a multitenant app, even when there is a single database.
Multitenant Equals Multipurpose
A multitenant app is nothing but a bunch of logically isolated and physically integrated instances, that is, tenants. One of the most widespread causative factors for using the multitenant approach is saving money. You don’t have to develop the same feature for each and every customer, while you can simply keep adding instances to an already existing app. A resource saved is a resource earned. This is one of the most widespread programming architectures in cloud computing, with Lambda, a serverless technology from AWS being a vivid example of how multitenancy can be a truly reasonable from the financial point of view decision. Frankly speaking, multitenancy is also something that the IT companies’ customers enjoy a lot. One business can come and buy an instant application and spare itself of waiting for the product to be developed. Meanwhile, the developers themselves, depending on the contract they sign with the customer, can resell the app’s features to other businesses as there is still enough place for the clients to join the party. While the app is hosted in one space, it can be used by multiple users. Sometimes, it might not be the best approach, especially for the companies that require all the information to be stored on their own services. Nonetheless, the advantages offered by multitenancy are quite obvious to perceive. The app is easier to support and manage, and it takes less resources to deal with it. What is more, the information-sharing capacity is being boosted, as the tenants can embark upon mutually-advantageous information exchange. Finally, those who keep claiming that multitenancy is not secure should know that each and every tenant can have its own private space within the server.Multitenancy Modes
As a matter of fact, there are three modes of implementing multitenant apps, as the correlation of instances and databases can always be gauged in accordance with the needs of the project.
