Cloud services are getting prominent with each passing day. More and more companies are adapting cloud services to run their applications. There are three types of cloud deployment models: Public Cloud, Private Cloud and Hybrid Cloud (mixture of Public and Private Cloud). Cloud deployment models dictate how data is stored, how customers interact with it and how applications (deployed on cloud) run. In this article, we will be analyzing the differences and use-cases of different types of cloud deployments. We would also be analyzing and discussing their advantages and disadvantages in this article.
