Flexibility:- it can easily can combine with the public cloud which leads to the high security feature
Location Independence:- since it was public we can use these cloud with respect to place and location
Scalability:- As we were having a pool of users the scalability can be high because it can scaled up or down based on the requirements
Disadvantages
