[MUSIC] Today's lesson, we'll dive into your computer system versus an Enterprise System, specifically virtualization. Today, we're going to discuss a little bit about how computer resources are used in your home versus what they're going to be used on the Enterprise level. Also, describe some of the benefits of using the technology that you all ready have at your home to bring really what we do in Enterprise to your home. We're going to also explain how personal computing systems can be used for Enterprise grade systems. Personal computing and resource consumption is one thing that we always need to be concerned with. Your personal computer that you may be using right now, let's just actually called it desktop. If you're using a desktop right now and you look at the system resources, you're going to realize that you're probably only using 5 to 10% of your computing power. If I looked at my desktop right now, I may be only using, even though it's a very powerful machine and it has a 750 watt power supply, I'm actually only using about 17 watts of that, why? Because I'm not using it for anything, I'm doing some word processing, I'm doing email. It's not being utilized like we would a typical processor on an Enterprise system, so that's why we have virtualization technology out there. Over the past several years, we've actually been able to take the processors that came out three, four, five years ago and still use them today. For example, the first generation of the i7 came out around six years ago. That's still a very valid platform to use when we want to test things or if we want to use them in our computer systems. Computers in general, like I said, really only use 5 to 10% of the resources. Now your RAM, it probably uses a little bit more RAM. But think about the latest Windows 10 build, we can get away with 4 to 6 gb of RAM just running Windows itself. So if we have 16 gigabytes of RAM, for example, then we're only using, what is that, 30% of the RAM. Virtualization allows us to do more, it allows us to process more, it allows us to build computer systems within computer systems. It allows for security, it allows for productivity and performance. I can take my computer that is only running 5 to 10% of resources and turn that into something that is utilizing 80 to 90% of system resources. The reason I want to do that is because I don't want to waste processing power. Our virtualization systems don't have to be expensive. We can actually run some of the latest processors and utilize those processors for very powerful systems on our home computers, or our laptops, for example. What we need is maybe an i5, an i7 from Intel or an AMD processor like the earlier FX chips or the new Ryzen chips that have just come out within the past few weeks, depending on when you're actually viewing this. Memory, we need about 8 gigs of RAM to run virtual systems effectively. We need some kind of virtualization software, so we can either download something like Oracle's Virtual Box or we can download VMWare Workstation or we can download VMWare Fusion. VMWare Workstation and VMWare Fusion are paid for virtualization platforms but Virtual Box is free. Also, if you're running a Windows system, Hyper V should be available to you as well in some of the editions that come with Windows. We also need enough storage to run multiple operating systems. Think about how much room your operating system has right now. If you're running a Windows system, we may see 20 GB or so of memory. Enterprise environments are more of everything, so more storage, more memory, more processing power and we, of course, have redundancy built into everything. Everything that we run here at UCCS is active, active. We've run two different data centers with the exact same technology that's writing in both places, only reading in one. Dual routing centers, for example, in case one data center goes down. Some of the smaller configurations, some of the smaller type Enterprise environments like we run here at UCCS, we have a virtualization platform that runs 14 blades, has around 884 cores in it with 3.5 terabytes of RAM. That may seem like a lot, and it kind of is, but we can't run thousands of systems, we only can run several hundred systems at a time. Personal computing, we can get away with using what we have to do some of this Enterprise grade architecture. This laptop, for example, here can run about four virtual machines through the virtualization technology and I run VMware Workstation on here. My desktop sitting in my office can run right around seven to ten virtual machines at a time just because the amount of resources that I have available to it. In conclusion, the computer that you're using now, if your using a desktop or a laptop, as long as you can meet some minimal specs like that i5 or i7 or AMD FX processor, we can use virtualization technology. We don't have to go to an Enterprise to run Enterprise grade architecture, we can use what we currently have to the most of its ability. Let's turn that 5 to 10% utilization into 50% or 60% utilization, you don't have to spend a lot of money developing your own Enterprise system. So get out there and test this virtualization software.
