IaaS vs PaaS vs SaaS: What's the Difference?

Infrastructure as a Service (IaaS) is an entity that offers scalable cloud resources, such as virtual machines, storage and bandwidth. Instead of buying these resources outright, companies purchase them on an ongoing basis from an IaaS when needed. Examples of an IaaS are AWS, Microsoft Azure and Google Compute Engine.

Platform as a Service (PaaS) is an entity that offers similar services as an IaaS, but they are geared toward the creation of web applications. So, while they offer scalable cloud resources, they also offer a framework that developers can use to build their applications upon. Examples of a PaaS are Google App Engine, Heroku and OpenShift.

Software as a Service (SaaS) is an entity that offers applications on the cloud. Instead of buying and installing applications on-premise and providing the infrastructure for them, such as storage, companies purchase on-going access to them through a SaaS. Examples of a SaaS are Google Apps, Dropbox and Salesforce.
