Dear Hassan,
I would like to recommend that you check the NIST Definition of Cloud Computing, which is widely accepted.
In my opinion, in particular the definitions of the Service Models Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) might help you with your question.
Cheers,
Steve

I can not say xactly but platform means the area on which you are running your app in cloud while infrastructure means the resource provided to you from the cloud as on demand to run your app
As far as infrastructure is concern, the devices you are working on, the configuration (hardware only), servers, memory, even space etc. are the infrastructure for your project whereas, operating system, programming languages and other programming tools contributes to platform for your project.
please See the following link

Hi Hassan,
In My view, We can split horizontally as 3 layers.
1. Infrastructure
2. Platform
3. Software
Base is the Infrastructure where your Platform is going to reside.
Infrastructure has a Operating System, Machine Architecture - 32 / 64 Bit.
Based on this , Software packages for Platform are installed.
If Infrastructure is 32 Bit, Your platform and Software will be a 32 Bit Program.
If Infrastructure is 64 Bit, Your platform and Software will be 32 / 64 Bit Program.
Platform is some thing which is required for developing / Deploying.
Ex for PaaS:
CloudForge - They have GIT / SVN in Cloud
WaveMaker - enable to develop / deploy application online , etc
Software - Software / Program which is going to run over Platform and Infrastructure,All these layers are inter depended on each other.
Infrastructure can be present without Platform.But a platform cannot be standalone or run on its own without an Infrastructure.

PaaS, or solution stack, offers a more comprehensive approach to the cost effective application deployment need of today’s developers. This service provides the necessary hardware architecture and software framework needed to put an application into service, without having to own, manage and upkeep all the required resources.
IaaS, or HaaS (Hardware as a Service), in comparison to the PaaS, provides equipment for operations, networking, data storage and hardware with the use of the internet, so that the subscriber is no longer confronted with location and purchase costs.
Even though the differences between PaaS and IaaS are very clear, there are advantages that weigh in favor of each one of them, depending on the clients necessities.
• SaaS applications are designed for end-users, delivered over the web
• PaaS is the set of tools and services designed to make coding and deploying those applications quick and efficient
• IaaS is the hardware and software that powers it all – servers, storage, networks, operating systems
Sometimes they are used interchangeably so it depends on the context. In today both hardware and software fall in those categories.
