What is IAAS , PAAS , SAAS??

Now we have to see what components are under IAAS Service of Any Cloud.

Services from 5 to 9 comes under the hood of IAAS(Infrastructure As a Service).

Let's understand with an example if a Company who name is ABC . So, If the  ABC company is using any of these services from 5 to 9 . That , means that company is using Infrastructure as a Service .

Many of you Don't know the what Virtulization means which is placed in 5th number in the above list.No worries keep reading Blog I have mentioned for every type of people . Whether they belongs to Non-Technical Background or Technical Background . Doesn't matter . Just Keep Reading Content

Explanation- it means when you video call to someone . Input is same means that if you meet that person in real time . So, you will talk to him/her the same thing you are also doing while in Video Call.you can also see him/her in real time you can also see her/him  while in the video Call . So, the point is that what is the difference between both scenario's is that in Video Call . The opposite person is not present in front of you. You can't touch him/her that is the difference. That Video Call Scenario is related to Virtualisation . Now Moving Ahead

The Services which are from 3rd to 4th are all Covered in Platform As a Service. Why Infrastructure as a Services are also included in Platform as a Service because you can't start a computer without a window and for installing window you should have hard disk or SSD . Where it will be kept . So it is like that their is a dependency between PAAS & IAAS. So I know you have some questions in your Mind just keep them with yourselves I have something more understandable . Now moving ahead to SAAS. 

The Services which are from 1 to 9th are all Covered in Software As a Service. Let's understand with an example if a Company who name is ABC . So, If the  ABC company is using any of these services from 1 to 2 . That , means that company is using Software as a Service  from cloud.It means its is using IAAS , PAAS , SAAS all the three Services.
