Make as if you are an IT admin and have to install a CRM app like SalesForce for your users. 


In this case, SaaS (software as a service) can be viewed as accessing the application directly through your web browser through purchasing of a subscription from SalesForce. This would be the top level in the as-a -service family. 


Going a level below, or PaaS ( Platform as a service), this can be viewed as having an operating system like Microsoft Windows server on top of which you install the CRM service for your users. 


Going another level below, you have the IaaS (Infrastructure as a service) or server or virtual server provisioned using VMWare where you have to build the whole OS together with installing the application for your users.


Hope this helps.

Hi, in a nutshell, the level of control over the operation, the price you pay for services and the flexibility.


IaaS: you design it according to your needs and requirements it’s usually the cheapest option, but requires more human power.


PaaS: think of it as an environment for the creation (development) of software or services in which you don’t need to control the underlying infrastructure.


SaaS: it’s end-user software completely managed by the provider. In many cases, you can customize it to your needs. It’s usually more costly but requires less human power and less implementation time. You can be up and running faster at the expense of losing some control over your infrastructure.

I hope that will help.

IaaS, provides you infrastructure services. If you want to buy a home, they provide you good location, good and secure land to build a house. To buy IaaS you need make sure it's a secure, stable and reliable service to run an application inside.


PaaS, provides you platforms. If you want to buy a home, they provide you good house, good building, functional and healthy rooms. To buy Paas you need to consider it's a safe, functional and supporting operating system for your applications.


SaaS, provides you application or software services. If you want to buy a home, they provide you rental house complete with its furniture and appliances. You just enter the house and live inside. SaaS must be built on top of good platform and infrastructure. Also, you need to make sure that applications work as you need
