Public Cloud Model
Public Cloudallows systems and services to be easily accessible to general public. The IT giants such as Google, Amazon and Microsoftoffer cloud services via Internet. The Public Cloud Model is shown in the diagram below.

Benefits
There are many benefits of deploying cloud as public cloud model. The following diagram shows some of those benefits:

Cost Effective
Sincepublic cloudshares same resources with large number of customers it turns out inexpensive.
Reliability
The public cloudemploys large number of resources from different locations. If any of the resources fails, public cloud can employ another one.
Flexibility
The public cloud can smoothly integrate with private cloud, which gives customers a flexible approach.
Location Independence
Public cloudservices are delivered through Internet, ensuring location independence.
Utility Style Costing
Public cloud is also based onpay-per-usemodel and resources are accessible whenever customer needs them.
High Scalability
Cloud resources are made available on demand from a pool of resources, i.e., they can be scaled up or down according the requirement.
Disadvantages
Here are some disadvantages of public cloud model:
Low Security
Inpublic cloud model,data is hosted off-site and resources are shared publicly, therefore does not ensure higher level of security.
Less Customizable
It is comparatively less customizable than private cloud.
