Multitenancy is described as various consumers of a cloud provider using the same computing resources in cloud computing. They share resources, but cloud customers don’t know each other, and the data is completely separate. Multi-tenancy is an important component of cloud computing, and without them, cloud services would be far less practical. Multi-tenant architecture is a feature of many types of public cloud computing, including IaaS, PaaS, SaaS, containers, and serverless computing.
Multi-tenancy in cloud computing is a software architecture that allows a single software instance to serve different groups of users. Software as a Service (SaaS) products are examples of a multi-tenant architecture. In cloud computing, multi-tenancy can also refer to shared hosting where different customers share server resources. Multi-tenancy is the opposite of single-tenancy when a software instance or computer system has end-users or groups of users. Multi-tenant applications typically include tenant customizations such as: For example, you can customize the look of your application or allow tenants to make decisions about specific access control permissions and user restrictions. Multi-tenancy is a topic covered under the cloud computing courses syllabus if you want to understand the topic in detail.
Benefits of Multi-Tenancy
Most benefits of cloud computing are only possible through multi-tenancy. The two main ways multi-tenancy can improve cloud computing are:
- Machines reserved for one tenant are inefficient because one tenant is unlikely to use all the machine’s computing power. The utilization of available resources is maximized by multiple tenants’ shared use of machines.
- Resources are shared by multiple customers, allowing cloud providers to serve more customers at a much lower cost than each customer using their dedicated infrastructure.
- If you invest in your hardware and software, it can reach capacity when demand is high or idle when demand is low. On the other hand, in a multi-tenant cloud, you can allocate a pool of resources to users who need it as your requirements scale up and down. As a public cloud provider customer, you have access to additional capacity when you require it, and you don’t have to pay.
The drawback of Multi-Tenancy
- No matter how secure, some organizations may not store data in a shared infrastructure due to regulatory requirements. In addition, security issues and corrupted data can spread from one tenant on the same computer to another, which is rare. If the cloud provider has properly configured the infrastructure, it should not occur. These security risks are mitigated because cloud providers can usually invest more in security than individual enterprises.
- If one tenant consumes excessive computing power, it can degrade the performance of other tenants. This shouldn’t happen if your cloud provider has set up your infrastructure correctly.
In cloud computing, applications and data are hosted on remote servers in various data centres and accessed over the Internet. Data and applications are centralized in the cloud rather than on individual client devices (such as laptops and smartphones) or servers in corporate offices.
