IaaS, PaaS or SaaS

Recently a person asked me which options should he take – IaaS, PaaS or SaaS? It was apparent from his questions that he has heard about the cloud terms have no clue as to what these mean.
 
Well in simple terms:
 
  • IaaS: Infrastructure as a Service means that you are hiring the infrastructure and will pay as you use
  •  PaaS: Platform as a Service means that you are hiring the platform and will pay as you use
  •  SaaS: Software as a Service means that you are hiring the application and will pay as you use
So find what exactly are you looking? Are you simple looking at an application or the infrastructure or the platform? So determine your needs, check the requirements and adopt the perfect cloud solution!
