This module is about cloud technology. I will start off with cloud market analysis. Looking into data from 2014, you will see three categories up here. The one over there is SaaS, which is Software as a Service, then you will see in the one in the middle is PaaS, which is Platform as a Service, and then you'll see IaaS right here, the one right here and that is Infrastructure as a Service. The Software, Platform, and Infrastructure as a Service are the three major categories of cloud computing support that can be provided. Their definition and what they can actually do for you is explained later in this lecture a couple of slides later. So, hang in there. First we'll do a market analysis. Look at it in three ways, number one, software represented in SaaS, Platform technology represented in PaaS, and then infrastructure represented in SaaS. Looking at the dimension of the vertical axis in SaaS, you can see on the top of the figure, there is a dollar sign and bn written on the top. That means that it is in units of billions of US dollars. On the top of PaaS, you'll see dollar sign and mn, which means that the vertical axis is in units of millions of US dollars. Then coming back to IaaS, Infrastructure as a Service, dollar sign and bn, which means that it is in units of billions of dollars. So, taking a look at what we have here, look at the growth in SaaS, software based cloud technology, how it is growing. Especially looking at over there, the vertical axis which is in units of billions of US dollars. Then looking into PaaS, Platform technology in the middle. You can see that the units are in hundreds of millions US dollar. Then you can see IaaS, which is also in units of billions of US dollars and the overall growth. From this it is evident that the need and the consumption of various cloud services regardless of being software platform or infrastructure, are in high demand, they're growing at extremely high rates, quickly, and therefore studying this module of cloud technology is so important. Now, we're going to compare these technologies based on a 2016 dataset which is included in here, in which the CAGR data in terms of percentage, is compared over here. One thing that you can see is that on the bottom of these blocks on the histogram, you can see the bottom is SaaS, which is Software as a Service and it is the most dominating compared to the other two in terms of overall CAGR percentage. This is why you can see the title of this part is top ten reasons to leverage SaaS for your business. Meaning that having SaaS based products in supporting Cloud computing technology, in addition, you will need various SaaS technologies to support your business growth. The second one over on the SaaS is the lighter green, which is the Infrastructure as a Service, IaaS, and it is smaller than the SaaS. However, it is still significant and also year-by-year from 2013 going up all the way to 2018 including predictions, you can see that it is consistently growing, not as much as SaaS, but it is significantly growing itself and we've seen that in a former version on the former page. On top of the three is the smallest one which is Platform as a Service, PaaS. However, it too is also growing significantly and you can see how it reaches the overall portion when compare the three. The next one is Amazon Leads the Race in Cloud computing, and you can see a significant overall accomplishment by the company of Amazon when it comes to cloud computing technology and services. Overall here, this is based on 2017 and the structure of Amazon Web Services, AWS for short, is added up and you can see that it's reaching 40 percent. Where the other secondary contenders Microsoft, Google, and IBM add up to 23 percent. You can see how good Amazon is doing in this term. Then the next 10 companies, meaning that excluding the big four over there, the next 10 combine over here and the rest of the others combine over here. This is also showing you that the four big players that you see here which include: Amazon, Microsoft, Google, and IBM, are dominating the cloud market. Looking into further details of services in Q2 of 2017, here we have a layout of Microsoft, IBM, and Google divided. In the former page, the three were added up. Now they're divided and looking at this comparing the companies, Amazon, you can see how dominant it is right now. That's why of course we need to study the Amazon Web Service systems in closer details. Overall first here, you see the big four listed up here and then the next 10 combined and the company names that support those. Then the rest of the market share is included down here. What type of growth was recently seen? That is right here. You can see that over the last four quarters, one year. Because each quarter is three months, four quarters make a year. So, over the past year of growth reaching up to the Q2 in 2017, you can see that Amazon has shown a growth of one percent. It was already large. So, one percent growth when you're already large is significant. Microsoft showing growth, IBM, and Google and you see the next 10 on how they have been growing and the overall balance of what happened over the last year since the Q2 of 2017 to result in this type of a distribution, is what you see in the overall data. Top cloud companies and services. So, we've just seen what the top four big companies are doing. They were Amazon Web Services (AWS), Microsoft. Then IBM and Google. So, it is worthy to take a closer look and to see how these big four are doing so well. What are the characteristics of their service? What distinguishes them from the others?
