In simple terms, cloud computing is storing and accessing data and applications via the internet rather than on your computer's hard drive. The cloud may be used to save files. The benefit is that it is simple to backup. They are a cost-effective solution for enterprises. They synchronize the files from the desktop automatically. Dropbox, for example, offers customers to access files and storage up to 1 terabyte for free.
There are three types of cloud computing deployment models: private cloud, public cloud, and hybrid cloud.
A private cloud environment is a specialized cloud environment for a single corporate organization, with physical components hosted on-premises or in a vendor's datacenter. This solution provides a high level of control because the private cloud is only accessed by a single company.
The public cloud stores and manages data and applications through the internet. It's entirely virtualized, allowing users to take use of pooled resources as needed.
