Question One

According to the United States National Institute for Standards and Technology (NIST), Cloud Computing is defined as:

A model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Based on the above definition, Cloud Computing has three service models known as Software-as-a-Service (SaaS), Platform-as-a-Service (PaaS), and Infrastructure-as-a-Service (IaaS). By using your own words, differentiate between these three service models and give an example to each one.
