IaaS: Infrastructure-as-a-Service or IaaS lets you create cloud-based infrastructure (servers, networks, and so on) in the cloud. Like on-premises, but without the complexity of data centers or infrastructure.

PaaS: Platform-as-a-Service or PaaS allows you to develop software on a cloud-based platform without worrying about infrastructure deployment. Less stress regarding OS/Hardware, but the greater power is given to the vendor.

SaaS: Software-as-a-Service or SaaS is a concept where the provider manages practically everything, and you only use the service, such as Office 365 or DropBox.

2 What are the main characteristics of cloud computing?
