Sharing is getting period we all know that. This concept has now traveled from the real world to the world of the web. but then again we also understand the value and importance of privacy and boundaries in the web world. How are these two contrasting ideas coexist in the same world? Technology has found the answer to that as well. It has come up with such a cloud computing architecture that will let the users access information from the same source while at the same time keeping their data safe and private. Such a cloud computing system is called a multi-tenant cloud system. What is it? Let’s find out!
What is a multi-tenant cloud?
The concept is not that hard to understand. Multi means more than one or multiple, and tenant generally refers to a person who occupies a piece of land on rent. For the ease of your understanding let us compare the structure of a multi-tenant cloud to that of an apartment building. As you may have noticed in an apartment building each one of the people living in it have their apartments. They share their personal space and their privacy. However, all of the residents do share common resources such as water and other such amenities in the building.
The above however was a definition of what those two terms mean generally. But what does multi-tenant mean in the cloud?
The concept remains the same. Multitenant in the cloud is a structure that entitles users and minds to share certain computing resources in private and public cloud systems. But the data of every such tenant or client remains isolated from another client’s data. The data you store there would not be visible to the others accessing similar resources such as yourself.
There exist individual compartments for storing the data of every such client. All of these compartments are well protected and grant access to the corresponding users only.
Are multi-tenant clouds and public clouds the same?
Another question that might have crossed your mind is that isn’t the structure of a multi-tenant cloud quite similar to that of a public cloud? Well, you are right. But then what is the difference between the two?
The major difference between the two is that in public cloud architecture the users are not granted any private space to store their data. In a public cloud environment, every client that visits the cloud resources has access to every piece of information over there. Privacy, in that case, is heavily compromised.

What are the benefits of using a multi-tenant cloud structured?
Using a multi-tenant cloud structure surely has its perks. Below given is a brief list of the benefits that a multi-tenant cloud architecture offers to its clients. Keep in mind that in this case, the clients can be individuals as well as organizations and establishments.
- First and foremost a multi-tenant cloud system offers better and more efficient use of existing storage unlike single-tenancy clouds. The same resource pool can be accessed by a wider group of individuals.
- The above really in turn again reduce costs of maintaining individual hardware resources as well. No need to maintain copies of data that you can access all the time at any time, right?
- This virtualization of storage also leaves a lot of room for flexibility. You can access the information that you need anywhere and at anytime.
- Last but not the least, multi-tenancy in cloud computing also guarantees maximum privacy for all its users. A piece of information stored by one of the clients can never be accessed by another client. This is a major advantage over public cloud systems.
There, however, and quite naturally, exist certain drawbacks to multi-tenancy in cloud computing as well. Let us go back to the example of the apartment building. There, if one of the residents is misusing the common resources, it will be difficult for the other residents to live in the apartment building. Similarly, if one such client exists in the cloud system who constantly keeps on using an inordinate quantity of computing services, it would then, naturally, slow down the performance also the entire structure. Above all, privacy risk always exists in the online world.
However, all of it that we have just discussed above can be avoided if the cloud service provider is professional and efficient enough. If that is sorted, multi-tenancy cloud is probably one of the best cloud architectures to go with.
