With a wide range of Cloud lessons already available at a deep technical level, this lesson is aimed as an introduction to those looking at Cloud Computing from the perspective of a beginner who may have no previous experience of the topic at all.

Before implementing or adopting Cloud technology, you will want to have an understanding of what it is exactly and what options you have when thinking about your deployment. This lesson covers a wide range of Cloud Computing topics areas, providing you with a solid foundation of understanding.

We will start by defining Cloud Computing, then we will explore what this definition means. We will look at the different deployment models such as Public, Private, and Hybrid Clouds before digging into what actually makes a Cloud a Cloud. Here we break down the Cloud model by looking at the key concepts and characteristics that make it so appealing to a wide range of organizations and individuals.

This lesson also looks at the different service models of Cloud Computing, Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS), providing examples and differences between each.

With all of these different deployment and service options, this lesson looks at ways other organizations are utilizing the Cloud with some common use cases that you may be familiar with.

Lastly, an overview is given on how typical on-premise data center solutions are reflected within the Cloud. Some people may already be aware of these solutions but are unsure of how certain infrastructure such as networks is architected from a Cloud Computing perspective. As well as networking, we will also look at Storage and compute (server) resources and how these are deployed in comparison to on-premise solutions.
