Types of Cloud Computing

Public Cloud: A Public Cloud is available to the public via internet. Gmail is an example of a Public Cloud.
Private Cloud: Private cloud offers privacy. It belongs to a specific user which may be individual, firm or a company. Big organizations being concerned about security prefer private clouds.
Hybrid Clouds: Hybrid clouds are a mix of both. One can control an internal database and use the public cloud when needed.
Characteristics:

1. On-demand self-service: One can use it whenever one needs it.
2. Broad network access: One can be able to access information from internet using any device from anywhere.
3. Resource pooling: Different clients can share the same space.
4. Rapid elasticity: Cloud can grow and shrink as per requirement of the clients.
5. Measured service: You can examine how often people are using the cloud. Many cloud service providers utilize a pay-as-you-go model to ensure that their clients are getting what they pay for.

This can be compared to electricity, water or gas. We pay for the amount we use.
Advantages:
Clients can back up their data at a remote secure location. No need to pay for infrastructure for storing it in their premises thus , saving the cost of space and infrastructure.
Disadvantages:

Sometimes the servers of service providing companies may get damaged due to natural disasters or internal bugs.
However , major cloud computing companies are more secure as they apply strict measures for the security of data.
