What are the different layers in cloud computing? Explain working of them.
-
I. Infrastructure as a Service (IAAS): IAAS providers give low-level abstractions of physical devices. Amazon Web Services (AWS) is an example of IAAS. AWS provides EC2 for computing, S3 buckets for storage etc. Mainly the resources in this layer are hardware like memory, processor speed, network bandwidth etc.
II. Platform as a Service (PAAS): PAAS providers offer managed services like Rails, Django etc. One good example of PAAS is Google App Engineer. These are the environments in which developers can develop sophisticated software with ease.
Developers just focus on developing software, whereas scaling and performance is handled by PAAS provider.
III. Software as a Service (SAAS): SAAS provider offer an actual working software application to clients. Salesforce and Github are two good examples of SAAS. They hide the underlying details of the software and just provide an interface to work on the system. Behind the scenes the version of Software can be easily changed.

Public Cloud
A public cloud is represented by a system whereby the infrastructure and services offered are off-site over the internet by a provider.
Private Cloud
A private cloud is represented by a system whereby the infrastructure and services are managed on a private network.
Hybrid Cloud
A hybrid cloud is simply a combination of private and public cloud. Some of the hybrid cloud elements are outsourced either externally or internally, but not all.

I will try to give a short answer to this. The three main layers of Cloud computing are as follows:
I. Infrastructure as a Service (IAAS): IAAS providers give low-level abstractions of physical devices. Amazon Web Services (AWS) is an example of IAAS. AWS provides EC2 for computing, S3 buckets for storage, etc. Mainly the resources in this layer are hardware like memory, processor speed, network bandwidth, etc.
II. Platform as a Service (PAAS): PAAS providers offer managed services like Rails, Django, etc. One good example of PAAS is Google App Engineer. These are the environments in which developers can develop sophisticated software with ease.
Developers just focus on developing software, whereas scaling and performance are handled by the PAAS provider.
III. Software as a Service (SAAS): SAAS providers offer an actual working software application to clients. Salesforce and Github are two good examples of SAAS. They hide the underlying details of the software and just provide an interface to work on the system. Behind the scenes, the version of Software can be easily changed.
