Multitenancy in Cloud Computing

This article will briefly discuss the essential topic, Multitenancy in Cloud Computing.

What do you mean by Cloud Computing?

Cloud computing can be considered one of the most critical and recent inventions to store a large amount of data that can be retrieved easily whenever any particular organization requires it.

Cloud computing is the most advanced form of technology that uses remote servers on the internet to perform the following operations: storing, managing, and accessing the data effectively and efficiently without any difficulties is only termed Cloud Computing.

The Operations that can be performed using the cloud computing are as follows:

       i.            Networking.

     ii.            Software Applications.

  iii.            Security.

  iv.            Data Storage.

     v.            Business Intelligence.

  vi.            And many more etc.

What do you understand by Multitenancy?

Multitenancy:

Multitenancy in cloud computing is usually defined as a particular form of cloud architecture where multiple numbers of clients of a single cloud vendor are used to share the same computing resources effectively and efficiently. 

Still, the clients using the same computing resources are pretty unaware of the sharing done between the two clients, and the sharing usually means effectively sharing the software resources. Multitenancy is usually considered an essential part of cloud computing; cloud services cannot be defined more practically without Multitenancy.

In this, every client is known as a tenant. In Multitenancy, the tenants have some control over the customization for the particular shared resources, which generally includes the following things to be done by the tenants that are as follows:

·       Tenants are usually responsible for controlling which particular users can access the shared resources.

·       And also responsible for how the application looks and feels.

·       They are not responsible for the customization of the code.

·       And many more etc.

 

Example:

The working of the Multitenancy is quite similar to the working of the particular local bank where as usual the customer of that particular local bank used to deposit their cash in the respective bank for security and many more etc., 

the advantage of depositing the cash over the bank by the customer is that they have the private account and other customers have no authorization to the bank account of other customers through every customer have their account in the same bank in the same way the Multitenancy also works- one bank many customers (clients).

 

Degree in the Multitenancy

In general, the Multitenancy usually comes in the three degrees they are as follows:

·       Low: In the Low degree, IaaS and PaaS are multi-tenant, whereas the SaaS is single-tenant.

·       Middle: In the Middle degree, the IaaS and PaaS are multi-tenant, and the small SaaS clusters are multi-tenant.

·       High: To a High degree, the IaaS, PaaS, and SaaS are considered fully multi-tenant.

 

Benefits of using Multitenancy:

There are various uses the Multitenancy that make cloud computing quite compatible and make its existence in the growing technology. Some of the benefits of the Multitenancy are as follows:

1)  Better use of resources: Better use of the resources is usually considered one of the most important benefits of the Multitenancy because the single-tenant cannot use one machine. Similarly, all the resources cannot be fully utilized by a particular single tenant, so it is essential to make the system available for all the tenants so that every tenant fully utilizes all the resources in the best possible manner.

 

2)  Lower Cost: Another most important benefit of using the Multitenancy is none other than the lower cost the means with the concept or with the technology of the Multitenancy, a cloud vendor can offer the use of their services to the multiple clients at the same time though reducing the cost of having more cloud vendor for the different-different customer.

 

3)  Can be easily scalable: Another most important benefit of using the Multitenancy is that it offers the advantage to the client of adding and removing the resources as per the requirement of the particular client. This can be perfectly flexible for organizations growing fast but quite unpredictable.

 

 

 

Drawbacks of Multitenancy

 

With some benefits, the Multitenancy is entirely encapsulated with the drawbacks too, which may include:

 

1)  Possible security risks and compliance issues:

One of the drawbacks of using Multitenancy is the security issue, as some of the data can be accessed by a third party. This breach occurred due to a faulty or accident, which may include a system malfunctioning or a bug in the software that might expose the data very frequently.

 

2)  More Complex In nature:

Multitenancy is quite complex and complicated as far as concerned with a single tenancy.

 

3)  Less Flexibility in Apps:

Another essential drawback of the Multitenancy is the less flexibility in the apps, which means the shared applications tend to be less flexible compared to other apps provided by the other tenant.
