Definition:
Cloud deployment models are different ways of using cloud services. They show how cloud systems work and who can use them. Each model is used for different needs, such as security, cost, and control.
There are four types of cloud deployment models:
- Public Cloud
- Private Cloud
- Hybrid Cloud
- Community Cloud
Private Cloud
A Private Cloud is a cloud system used exclusively by a specific user, company, or organization. It is not for public use. It can be used only by members of the organization. People outside the organization cannot use it.
For example, a hospital may use a private cloud to manage patient records, or a bank may use it to manage customer information. Different security methods, such as usernames and passwords, are used to protect the cloud and control who can access it.
Public Cloud
A Public Cloud is a cloud system that is open to everyone. Users can use cloud services on the internet and share files and resources with other authorized users.
For example, Google Drive, Gmail, and Dropbox are public cloud services that anyone can use. The cloud provider manages the cloud system, so users can use cloud services without handling servers and other technical resources.
Hybrid Cloud
A Hybrid Cloud is a cloud system that uses both public cloud and private cloud together. Data and applications can move from one cloud system to another.
For example, a company may store confidential data in a private cloud and use public cloud services, AWS or Google Cloud, for general work. The cloud provider manages both systems and makes them work together.
Community Cloud
A Community Cloud is a cloud system shared by a group of organizations that have similar needs or goals. It is not available for public use.
For example, several hospitals may use a community cloud to store and manage patient records. The cloud provider manages the system, and only member organizations can use it.
