What Is Cloud Computing?

With a wide range of Cloud courses already available at a deep technical level, this course 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 course 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 course 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 course 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.

Hello, and welcome to this course what is Cloud Computing. This is a question that many people ask, because we hear the term all the time in the IT industry and beyond. But what is it? What does it comprise of, why is it so prevalent and key to business development? This course will aim to answer all of those questions. Before we start, I would like to introduce myself. My name is Stuart Scott. I'm one of the trainers here at Cloud Academy, specializing in AWS, Amazon Web Services. Feel free to connect with me with any questions, using the details shared on the screen. Alternatively, you can always get in touch with us here at Cloud Academy by sending an email to 

This course is intended for anyone who wants to learn about Cloud Computing, who may have no or very little knowledge of it currently. It's for those of you who are looking to learn more about the Cloud, to decide if it's something you want to adopt within your business, or those of you that may be seeking a career move and want to learn the foundation of Cloud principles, then this course is for you. 

As this is a foundation and beginner course at Cloud Computing, I shall be discussing explaining the following key areas. Starting with, what is Cloud Computing. Here I should give you a definition of what it is in its most simplest form. We'll then look at Cloud deployment models, and within this lecture, I shall be reviewing and discussing three different models that you should be aware of. Next, I'll look at some key Cloud concepts, and here I shall explain some of the key concepts that apply to Cloud Computing. 

Following this, I'll be looking at different Cloud service models, and these differ from deployment models and focus more on the services offered by the Cloud. So I will dive into each of these, giving you an explanation of how they differ. Then I'll look at some common use cases of Cloud Computing, and here I should give a few examples of what enterprises are using Cloud Computing for, to drive their business and operations forward. 

Then I'll look at how data center architecture is reflected within the Cloud. So in this lecture, I explain how certain technology that we use on premises today, such as routes and switches, are reflected within the public Cloud. And then finally, there'll be a summary lecture, highlighting the key points from all the previous lectures. On completion of this course, you will have a comprehensive understanding of Cloud Computing along with its key concepts and benefits. This will allow you to determine when Cloud Computing should be used and which model and service to deploy. It will also give you a solid foundation to continue on with deeper learning about the Cloud and other Cloud service providers, such as Amazon Web Services, AWS, Microsoft Azure, and the Google Cloud Platform, GCP. 

Although not essential for this course, it would be advantageous if you have a basic understanding of Server hardware components and a basic understanding of what a datacenter is. Feedback on our courses here at Cloud Academy are valuable to both us as trainers and any students looking to take the same course in the future. If you have any feedback, positive or negative, it would be greatly appreciated if you could send an email to That brings me to the end of this lecture, coming up next I'll answer the question, "What is Cloud Computing?"
