IAAS | PAAS | SAAS |
IAAS is known as an Infrastructure as a Service, here you will get a raw hardware as a service from the cloud provider. It means, you get a server which can be configured as per your necessities or desire. | PAAS is known as a Platform as a Service, here you will get a platform which can be utilized for publishing data without the need to provide access for the OS or other underlying software. | SAAS is known as Software as a Service, here you will get software as a service without the need to purchase it. And, it does not require assistance from any infrastructure or platform. |
Amazon EC2 and Azure VM are some of the examples of IAAS. | Web apps and Mobile apps in Azure are some of the examples of PAAS. | An example for SAAS is when you actually launch any VM in a particular Azure, you will not buy the specific OS but you will pay the rent for the time duration you used the instance. |
Some of the cloud deployment methods are as follows: Public Cloud, Private Cloud and Hybrid Cloud.
Public Cloud | Private Cloud | Hybrid Cloud |

The three types of roles that are being implemented in the Windows Azure are as follows: Web Role, Worker Role and Virtual Machine Role.
Web role provides front-end web solutions which are similar to the ASP.NET application. On facilitating, it is known that Azure will cater other required services and IIS.
Worker role in Windows Azure is used to run longer activities and it caters essential solutions for background services.
Both the web and worker roles are effectively executed on the virtual machines while the virtual machine role assures access to the client’s to edit or make changes to the virtual machine on which both the web and the worker roles are efficiently running.

The process of adding extra instances to scaling is often termed as scaling out. Also, Microsoft Azure ensures prompt scaling up with the help of bigger roles apart from utilizing a wide range of other role instances. With the help of incorporating the process of expelling and adding various role instances to the Microsoft Azure application while performing, we can actually make adjustments to the application in line with the cost involved in running the application.

- It is used to send and activate any particular services
- It can be used to monitor all the services health
- It can also be used to release and allocate several resources
- It can be used to terminate, provision VM and more
Storage keys also known as the access keys can be used in the validation mode to access the storage services account present and to control the available data as per our requirements. We have two access keys in Windows Azure namely primary access keys and secondary access keys, using which we can confirm any such applications to the storage.
