What is multi tenancy in cloud computing?

Multi tenancy is a cloud computing model where a single shared system serves multiple customers, called tenants, while keeping each tenant’s data and settings isolated from the others. It is how cloud providers serve thousands of customers efficiently.

The shared resources, servers, databases, and computing power, are pooled and divided logically rather than physically. You get the benefits of dedicated software without the cost of dedicated hardware.

It is a spectrum, not a switch. Some systems share almost everything. Others share only the hardware and keep a separate database per tenant. The right level depends on your security and performance needs.

Is multi tenancy secure?

Yes, when it is built correctly. Strong isolation between tenants is what keeps shared systems safe.
