There are two modes in Saas, and they are as below
i) Fine grain multi-tenancy
ii) Simple multi-tenancy.
In the case of the former, the resources are shared by many with the functionality remaining the same. On the other hand, in the latter case, every user has an independent resource and thus differs from other users. This is the reason why simple multiple tenancies are considered the most efficient mode.
Such platforms are the main component in AWS, thus, when you prepare for an interview on this topic, makes sure you study Cloud Security Interview Questions too.
