Public Cloud
Private Cloud
Hybrid Cloud
What is public cloud?
Open to anyone, billed as pay-for-use. Amazon Web Services, Microsoft Azure, Google Cloud Platform, and Digital Ocean
What is private cloud?

What is hybrid cloud?
Deploying different pieces to different cloud deployments. Perhaps the front end is public and the back end services stay private
What does the course describe as the best cost cutting way to utilize the cloud?
