Cloud Computing:

Cloud Computing is an application on the remote server which can be accessed through internet and browser only.
e.g.  such as Gmail, Twitter, YouTube and Virtual Server (Server at remote location) etc.
For a instance, Videos is in YouTube application on remote server not on your local system.

IaaS (Infrastructure as a Service):

IaaS is a virtual server which has to be connected through internet, on which you can install software such as Operating System, Application Software etc. 
             It has scalability business concept, where you can increase or decrease your resources subscription as per your requirements, which makes it cost effective, riskless and maintenance less service. It helps us to be more focused on business rather than infrastructure.

e.g. Amazon Web Service ECS (Processor, Memory and Storage etc).

PaaS (Platform as a Service):
PaaS is a development platform bundled with different types of preinstalled software, where you will get the sandbox to develop and test your applications by using prebuilt properties, methods and components. This concept makes development easy, fast and cost effective.
e.g. Heroku and Force.com both belongs to Salesforce.com (Properties, Methods and Component Bundles etc).

SaaS (Software as a Service):
SaaS  is a combination of IaaS and PaaS services, which means you will get all compatible hardware and software to develop your application.
e.g. Salesforce CRM coming with subscription based database storage and prebuilt functionalities as software.
