Multi tenancy is a type of architecture in which a single instance of a software application serves multiple customers, where each customer is called a tenant. A tenant can customize some parts of the application, but not the application's code. Multi tenancy can be identified as a model where each computer has accounts and users can log into their accounts and share disk space and CPU resources. Multi tenant computing takes advantage of resource sharing, virtualization and remote access.

And that's where this really leads to a revolution: a cloud native revolution!
