Detailed explanation-1: -Most public cloud providers use the multi-tenancy model. It allows them to run servers with single instances, which is less expensive and helps to streamline updates. There are three multi-tenancy models and each has its own level of complexity and cost.
Detailed explanation-2: -Multi-tenancy is synonymous with the term “public cloud”, as the resources used are shared by multiple organizations. This leads to greater efficiency, amazing scalability and lower costs, all of which are huge draws of public cloud computing.
