What are the differences between Private and Public Cloud Computing?

B. private cloud is managed by a single party & public cloud is managed by third-party
C. private cloud is on-premises & public cloud is off-premises
D. unknown choice
Correct Answer: A
Explanation/Reference:
Enterprise Private Cloud
It’s yours, you own it and control it
More predictable and reliable
More secure
On demand computing for an existing application
Public Cloud
Could have “noisy neighbors”
Applications may have to be redesigned and this could cause failure
Performance may be unpredictable at times
Transition has to be made and it could be tough. There is a lot more to the transition than just “moving a VM”
More ideal for a newly written application that was architected for the public cloud
