1 1 00:00:00,290 --> 00:00:01,810 Cloud Computing. 2 2 00:00:01,810 --> 00:00:03,980 The last piece of virtualization technology 3 3 00:00:03,980 --> 00:00:06,180 that we want to cover is cloud computing. 4 4 00:00:06,180 --> 00:00:07,780 Now that's because most cloud 5 5 00:00:07,780 --> 00:00:10,630 is just a mixture of a bunch of virtualization technologies. 6 6 00:00:10,630 --> 00:00:13,660 So in this lesson, we're going to talk about how that works. 7 7 00:00:13,660 --> 00:00:15,130 When you're dealing with cloud computing, 8 8 00:00:15,130 --> 00:00:18,000 there really are four major ways that it's going to be done. 9 9 00:00:18,000 --> 00:00:20,190 There's a private cloud, a public cloud, 10 10 00:00:20,190 --> 00:00:22,580 a hybrid cloud, and a community cloud. 11 11 00:00:22,580 --> 00:00:24,280 Now, when you're dealing with a private cloud, 12 12 00:00:24,280 --> 00:00:26,220 this is where your systems and your users 13 13 00:00:26,220 --> 00:00:28,100 only have access to other devices 14 14 00:00:28,100 --> 00:00:30,290 within the same private cloud or system. 15 15 00:00:30,290 --> 00:00:33,560 And this is going to add to the security of that cloud. 16 16 00:00:33,560 --> 00:00:35,170 When you're dealing with a public cloud, 17 17 00:00:35,170 --> 00:00:37,310 the systems and the users can interact with devices 18 18 00:00:37,310 --> 00:00:38,620 on public networks, 19 19 00:00:38,620 --> 00:00:41,270 such as the internet and other cloud providers. 20 20 00:00:41,270 --> 00:00:43,320 Now, when you deal with the hybrid cloud, 21 21 00:00:43,320 --> 00:00:45,600 this is going to be a combination of both public 22 22 00:00:45,600 --> 00:00:47,080 and private clouds. 23 23 00:00:47,080 --> 00:00:48,670 Now, what would this look like? 24 24 00:00:48,670 --> 00:00:51,090 Well, let's take the example of a private cloud. 25 25 00:00:51,090 --> 00:00:52,470 Something like the GovCloud, 26 26 00:00:52,470 --> 00:00:54,360 which is made by the US government. 27 27 00:00:54,360 --> 00:00:57,070 This is hosted on Amazon and AWS servers, 28 28 00:00:57,070 --> 00:00:58,610 as well as Microsoft servers, 29 29 00:00:58,610 --> 00:01:00,900 but only government agencies can touch it. 30 30 00:01:00,900 --> 00:01:03,670 And only government data is going to be stored within it. 31 31 00:01:03,670 --> 00:01:06,000 This is considered a private cloud. 32 32 00:01:06,000 --> 00:01:08,380 Now on the other hand, there's a public cloud 33 33 00:01:08,380 --> 00:01:10,520 and this might be something like Google Drive, 34 34 00:01:10,520 --> 00:01:13,130 because anybody can sign up for Google Drive and use it. 35 35 00:01:13,130 --> 00:01:14,610 My data is in Google Drive, 36 36 00:01:14,610 --> 00:01:16,110 your data's on Google Drive. 37 37 00:01:16,110 --> 00:01:19,200 And we can even commingle our data inside of Google drive. 38 38 00:01:19,200 --> 00:01:21,550 This is what makes it a public cloud. 39 39 00:01:21,550 --> 00:01:23,170 Now in a hybrid solution, 40 40 00:01:23,170 --> 00:01:25,330 we can mix a little bit of both. 41 41 00:01:25,330 --> 00:01:27,090 For example, we might have parts of it 42 42 00:01:27,090 --> 00:01:28,000 that are going to be private 43 43 00:01:28,000 --> 00:01:29,820 and parts of it that are going to be public. 44 44 00:01:29,820 --> 00:01:32,220 Maybe our accounting data is very special 45 45 00:01:32,220 --> 00:01:33,980 and we want to make sure it's in a private cloud, 46 46 00:01:33,980 --> 00:01:37,330 but our human resource data might be in a public cloud. 47 47 00:01:37,330 --> 00:01:39,270 And we can mix those two things together 48 48 00:01:39,270 --> 00:01:40,540 by connecting them. 49 49 00:01:40,540 --> 00:01:42,510 It really depends on how you want to implement this 50 50 00:01:42,510 --> 00:01:43,890 inside your organization. 51 51 00:01:43,890 --> 00:01:45,610 But when you're dealing with a hybrid cloud, 52 52 00:01:45,610 --> 00:01:47,740 you have the ability to have both parts of public 53 53 00:01:47,740 --> 00:01:50,190 and parts of private working together. 54 54 00:01:50,190 --> 00:01:52,060 For example, in the US government, 55 55 00:01:52,060 --> 00:01:53,570 they have a private government cloud 56 56 00:01:53,570 --> 00:01:55,800 that we already talked about called the GovCloud, 57 57 00:01:55,800 --> 00:01:58,550 but they've also used some public cloud services 58 58 00:01:58,550 --> 00:02:01,590 like Microsoft Teams as part of their CVR environment, 59 59 00:02:01,590 --> 00:02:04,360 which was used during their COVID-19 pandemic response 60 60 00:02:04,360 --> 00:02:05,770 back in 2020. 61 61 00:02:05,770 --> 00:02:07,660 Now, CVR is just an acronym 62 62 00:02:07,660 --> 00:02:10,670 that stood for commercial virtual remote environment. 63 63 00:02:10,670 --> 00:02:13,010 And basically it was just a rebranded version 64 64 00:02:13,010 --> 00:02:16,270 of Microsoft Office 365 and Microsoft Teams 65 65 00:02:16,270 --> 00:02:18,790 that was issued to government and military employees to use 66 66 00:02:18,790 --> 00:02:20,290 during the pandemic. 67 67 00:02:20,290 --> 00:02:23,190 The fourth type of cloud is known as a community cloud. 68 68 00:02:23,190 --> 00:02:25,550 Now a community cloud inside of cloud computing 69 69 00:02:25,550 --> 00:02:28,190 is a collaborative effort in which infrastructure is shared 70 70 00:02:28,190 --> 00:02:31,060 between several organizations from a specific community 71 71 00:02:31,060 --> 00:02:32,460 with common concerns. 72 72 00:02:32,460 --> 00:02:33,990 And these can be managed internally 73 73 00:02:33,990 --> 00:02:35,440 or by third parties, 74 74 00:02:35,440 --> 00:02:38,260 and then they can be hosted internally or externally. 75 75 00:02:38,260 --> 00:02:40,390 For example, there could be a cloud service 76 76 00:02:40,390 --> 00:02:42,350 that's created specifically for banks 77 77 00:02:42,350 --> 00:02:43,970 by a group of banks. 78 78 00:02:43,970 --> 00:02:46,110 Each of these banks may provide either funding, 79 79 00:02:46,110 --> 00:02:48,920 expertise or personnel to create this cloud. 80 80 00:02:48,920 --> 00:02:51,750 And then all the members could benefit from its use. 81 81 00:02:51,750 --> 00:02:53,290 To make this work effectively, 82 82 00:02:53,290 --> 00:02:55,520 the community cloud solution is usually going to be designed 83 83 00:02:55,520 --> 00:02:57,320 as a multi-tenant platform. 84 84 00:02:57,320 --> 00:02:58,560 This way it can be accessed 85 85 00:02:58,560 --> 00:03:00,230 by each of the contributing members, 86 86 00:03:00,230 --> 00:03:02,090 but they each have their own portion of it 87 87 00:03:02,090 --> 00:03:03,520 and their own data. 88 88 00:03:03,520 --> 00:03:05,470 This is why we call it a community cloud, 89 89 00:03:05,470 --> 00:03:06,303 because it's built 90 90 00:03:06,303 --> 00:03:08,690 and used by a specific community of users. 91 91 00:03:08,690 --> 00:03:11,030 Now, in addition to these four types of clouds, 92 92 00:03:11,030 --> 00:03:14,000 there's also going to be five models of cloud computing. 93 93 00:03:14,000 --> 00:03:16,260 The five models of cloud computing are NaaS, 94 94 00:03:16,260 --> 00:03:20,420 IaaS, SaaS, PaaS and DaaS. 95 95 00:03:20,420 --> 00:03:22,440 This stands for Network as a Service, 96 96 00:03:22,440 --> 00:03:23,850 Infrastructure as a Service, 97 97 00:03:23,850 --> 00:03:25,270 Software as a Service, 98 98 00:03:25,270 --> 00:03:26,390 Platform as a Service, 99 99 00:03:26,390 --> 00:03:28,040 and Desktop as a Service. 100 100 00:03:28,040 --> 00:03:30,110 Let's take a look at each one of these. 101 101 00:03:30,110 --> 00:03:32,583 First, we have Network as a Service or NaaS. 102 102 00:03:33,910 --> 00:03:36,360 This is going to allow for the outsourcing of your network 103 103 00:03:36,360 --> 00:03:37,860 to a service provider. 104 104 00:03:37,860 --> 00:03:39,450 This is where all those virtual routers 105 105 00:03:39,450 --> 00:03:42,140 and switches and firewalls are going to come into play. 106 106 00:03:42,140 --> 00:03:43,670 All of this can be hosted offsite 107 107 00:03:43,670 --> 00:03:44,980 at the provider's location, 108 108 00:03:44,980 --> 00:03:46,800 and they put it into their data center. 109 109 00:03:46,800 --> 00:03:49,310 And you as the customer are going to be charged for usage 110 110 00:03:49,310 --> 00:03:50,470 based on the number of hours 111 111 00:03:50,470 --> 00:03:52,630 or the amount of bandwidth that's being used. 112 112 00:03:52,630 --> 00:03:55,410 Essentially your network capabilities are going to be provided 113 113 00:03:55,410 --> 00:03:57,050 as a common utility. 114 114 00:03:57,050 --> 00:03:59,880 A great example of this is going to be Route 53 115 115 00:03:59,880 --> 00:04:03,490 or Amazon's VPC, Virtual Private Cloud offerings. 116 116 00:04:03,490 --> 00:04:06,360 Both of these are Network as a Service options. 117 117 00:04:06,360 --> 00:04:08,340 Now, in addition to Network as a Service, 118 118 00:04:08,340 --> 00:04:11,520 there's Infrastructure as a Service or IaaS. 119 119 00:04:11,520 --> 00:04:13,100 Now Infrastructure as a Service 120 120 00:04:13,100 --> 00:04:15,430 is going to allow outsourcing of the infrastructure 121 121 00:04:15,430 --> 00:04:17,960 of your servers and desktops to the service provider, 122 122 00:04:17,960 --> 00:04:20,400 in addition to outsourcing that network. 123 123 00:04:20,400 --> 00:04:23,250 Now, if I wanted to host virtual servers hosted by Amazon, 124 124 00:04:23,250 --> 00:04:25,690 I can use AWS, or if I want to use Microsoft, 125 125 00:04:25,690 --> 00:04:26,970 I'm going to use Azure. 126 126 00:04:26,970 --> 00:04:29,350 All of that would be Infrastructure as a Service. 127 127 00:04:29,350 --> 00:04:30,720 All of this virtualized equipment 128 128 00:04:30,720 --> 00:04:33,640 is being hosted offsite at that service provider's location. 129 129 00:04:33,640 --> 00:04:36,140 And again, I'm going to be charged for usage 130 130 00:04:36,140 --> 00:04:37,580 based on the hours used, 131 131 00:04:37,580 --> 00:04:38,900 processing power used, 132 132 00:04:38,900 --> 00:04:40,560 bandwidth, the amount of memory, 133 133 00:04:40,560 --> 00:04:42,920 and any other factors like that, that they want to use. 134 134 00:04:42,920 --> 00:04:45,280 Essentially, it's being charged like a utility 135 135 00:04:45,280 --> 00:04:46,930 where you get a monthly bill every month 136 136 00:04:46,930 --> 00:04:48,520 for the amount you've used. 137 137 00:04:48,520 --> 00:04:51,110 For example, my website, diontraining.com, 138 138 00:04:51,110 --> 00:04:53,600 we use Infrastructure as a Service to host it 139 139 00:04:53,600 --> 00:04:55,200 because we've outsourced the servers 140 140 00:04:55,200 --> 00:04:57,490 and that hosting to this third party cloud company. 141 141 00:04:57,490 --> 00:04:58,440 And they charge us 142 142 00:04:58,440 --> 00:05:00,040 based on the amount of bandwidth that we use 143 143 00:05:00,040 --> 00:05:02,990 and the number of requests we get each month from students. 144 144 00:05:02,990 --> 00:05:06,800 Next, we have Software as a Service or SaaS. 145 145 00:05:06,800 --> 00:05:07,720 This is where the user 146 146 00:05:07,720 --> 00:05:09,800 is going to interact with a web-based application. 147 147 00:05:09,800 --> 00:05:11,800 And the details of how that application work 148 148 00:05:11,800 --> 00:05:13,510 is actually going to be hidden from the user, 149 149 00:05:13,510 --> 00:05:15,730 because honestly, our users don't really care 150 150 00:05:15,730 --> 00:05:17,010 about the details anyway, 151 151 00:05:17,010 --> 00:05:18,410 they just want the end product 152 152 00:05:18,410 --> 00:05:19,700 and the end result. 153 153 00:05:19,700 --> 00:05:22,980 Some great examples of this are things like Office 365 154 154 00:05:22,980 --> 00:05:25,270 or Google Docs or Google Sheets. 155 155 00:05:25,270 --> 00:05:27,670 All of these provide the end user with an application 156 156 00:05:27,670 --> 00:05:30,750 that is web-based and we're paying for it as a utility. 157 157 00:05:30,750 --> 00:05:32,240 Now, again, as an end-user, 158 158 00:05:32,240 --> 00:05:33,410 all I care about is, 159 159 00:05:33,410 --> 00:05:35,640 can I do what I need to do with the software? 160 160 00:05:35,640 --> 00:05:37,630 For example, if I need to make a spreadsheet, 161 161 00:05:37,630 --> 00:05:39,020 I can fire up my web browser, 162 162 00:05:39,020 --> 00:05:40,680 go to sheets.google.com 163 163 00:05:40,680 --> 00:05:42,580 and then start creating that spreadsheet. 164 164 00:05:42,580 --> 00:05:45,280 If I can do this, then the SaaS product is doing its job, 165 165 00:05:45,280 --> 00:05:47,400 and I am a satisfied customer. 166 166 00:05:47,400 --> 00:05:48,970 Now I don't have to install any software 167 167 00:05:48,970 --> 00:05:49,870 or configure it. 168 168 00:05:49,870 --> 00:05:51,860 All I have to do is log into the website 169 169 00:05:51,860 --> 00:05:53,490 and use that to create spreadsheets. 170 170 00:05:53,490 --> 00:05:55,380 So it meets my needs. 171 171 00:05:55,380 --> 00:05:57,290 Now, another great thing about SaaS products 172 172 00:05:57,290 --> 00:05:59,500 is they are really easy, really fast, 173 173 00:05:59,500 --> 00:06:00,900 and as an administrator, 174 174 00:06:00,900 --> 00:06:01,733 I don't have to worry 175 175 00:06:01,733 --> 00:06:04,020 about all the backend configuration and details. 176 176 00:06:04,020 --> 00:06:07,100 Instead, my company just pays an annual service fee 177 177 00:06:07,100 --> 00:06:08,350 or a monthly service fee, 178 178 00:06:08,350 --> 00:06:11,460 and we get access to that piece of software in the cloud. 179 179 00:06:11,460 --> 00:06:13,360 These days, more and more software 180 180 00:06:13,360 --> 00:06:15,580 sold under the Software as a Service model. 181 181 00:06:15,580 --> 00:06:16,570 In my company, 182 182 00:06:16,570 --> 00:06:19,170 we use things like Google Sheets and Google Docs, 183 183 00:06:19,170 --> 00:06:21,130 but we also use QuickBooks Online. 184 184 00:06:21,130 --> 00:06:23,300 And we also use Adobe. 185 185 00:06:23,300 --> 00:06:25,400 These days more and more software sold 186 186 00:06:25,400 --> 00:06:27,320 under the Software as a Service model. 187 187 00:06:27,320 --> 00:06:30,450 In fact, if using Adobe Photoshop or Adobe Premiere, 188 188 00:06:30,450 --> 00:06:32,640 those are still considered Software as a Service 189 189 00:06:32,640 --> 00:06:34,620 because there's a monthly fee associated with it 190 190 00:06:34,620 --> 00:06:35,640 that you have to keep paying 191 191 00:06:35,640 --> 00:06:37,280 in order to use that software. 192 192 00:06:37,280 --> 00:06:38,840 Now, this software is still going to be installed 193 193 00:06:38,840 --> 00:06:39,940 locally on your machine, 194 194 00:06:39,940 --> 00:06:41,720 and it's not truly web-based, 195 195 00:06:41,720 --> 00:06:44,050 but that's only because of the processing needs 196 196 00:06:44,050 --> 00:06:46,260 of these tools because you're dealing with video editing 197 197 00:06:46,260 --> 00:06:47,440 and photo editing. 198 198 00:06:47,440 --> 00:06:49,080 These tools had to be installed locally 199 199 00:06:49,080 --> 00:06:50,560 to take advantage of your computer, 200 200 00:06:50,560 --> 00:06:52,750 and its more intensive processing power. 201 201 00:06:52,750 --> 00:06:54,780 But every time you log into that software, 202 202 00:06:54,780 --> 00:06:55,980 it's going to reach out to Adobe 203 203 00:06:55,980 --> 00:06:57,720 and check to see if your software license 204 204 00:06:57,720 --> 00:06:58,760 is still up to date, 205 205 00:06:58,760 --> 00:07:00,440 because you have to pay that monthly fee 206 206 00:07:00,440 --> 00:07:02,680 because it's Software as a Service. 207 207 00:07:02,680 --> 00:07:05,190 Now, one of the key features of Software as a Service 208 208 00:07:05,190 --> 00:07:06,970 is that they are constantly being updated 209 209 00:07:06,970 --> 00:07:08,810 and upgraded on your behalf. 210 210 00:07:08,810 --> 00:07:10,890 In the old days, when you bought Adobe, 211 211 00:07:10,890 --> 00:07:12,310 it was a traditional software. 212 212 00:07:12,310 --> 00:07:14,500 You bought the license for one version of that software, 213 213 00:07:14,500 --> 00:07:15,570 and that was it. 214 214 00:07:15,570 --> 00:07:17,130 But with Software as a Service, 215 215 00:07:17,130 --> 00:07:19,840 you're paying this monthly fee time and time again, 216 216 00:07:19,840 --> 00:07:20,890 and in trade for that, 217 217 00:07:20,890 --> 00:07:23,370 you're getting a constantly updated piece of software 218 218 00:07:23,370 --> 00:07:25,040 with the latest and greatest version, 219 219 00:07:25,040 --> 00:07:26,660 all the security bugs are being worked out, 220 220 00:07:26,660 --> 00:07:29,780 and you're getting new features all the time. 221 221 00:07:29,780 --> 00:07:33,320 Next, we have Platform as a Service or PaaS. 222 222 00:07:33,320 --> 00:07:34,670 Now Platform as a Service 223 223 00:07:34,670 --> 00:07:36,600 is going to give you a development platform 224 224 00:07:36,600 --> 00:07:38,870 if you're a company that's going to be developing applications 225 225 00:07:38,870 --> 00:07:41,360 and you don't want to maintain your own infrastructure. 226 226 00:07:41,360 --> 00:07:43,540 When I build my courses in my lab environments, 227 227 00:07:43,540 --> 00:07:45,280 I use Platform as a Service, 228 228 00:07:45,280 --> 00:07:46,280 because I don't want to have to worry 229 229 00:07:46,280 --> 00:07:48,130 about building all the virtual labs myself 230 230 00:07:48,130 --> 00:07:50,400 and all the underlying code to host them. 231 231 00:07:50,400 --> 00:07:52,770 Instead, I want to build the virtual machine 232 232 00:07:52,770 --> 00:07:54,460 and give the experience of troubleshooting 233 233 00:07:54,460 --> 00:07:56,110 and maintaining that particular equipment 234 234 00:07:56,110 --> 00:07:57,760 within a particular lab. 235 235 00:07:57,760 --> 00:07:59,970 This way I don't have to deal with all the hosting needs 236 236 00:07:59,970 --> 00:08:01,020 and the networking needs 237 237 00:08:01,020 --> 00:08:03,680 and all the other stuff that goes into providing these labs. 238 238 00:08:03,680 --> 00:08:06,640 Instead, I can get what I need right out of it 239 239 00:08:06,640 --> 00:08:08,620 by using Platform as a Service. 240 240 00:08:08,620 --> 00:08:09,730 This is why I outsource 241 241 00:08:09,730 --> 00:08:11,500 under this Platform as a Service model. 242 242 00:08:11,500 --> 00:08:13,650 It makes my life much easier. 243 243 00:08:13,650 --> 00:08:15,900 Now, some great examples of Platform as a Service 244 244 00:08:15,900 --> 00:08:18,700 are things like Pivotal, OpenShift, and Apprenda, 245 245 00:08:18,700 --> 00:08:20,740 as well as many other solutions out there. 246 246 00:08:20,740 --> 00:08:23,230 If you work as a coder or a web programmer, 247 247 00:08:23,230 --> 00:08:25,320 or you work in a software development firm, 248 248 00:08:25,320 --> 00:08:27,137 there's going to be a lot of Platforms as a Service 249 249 00:08:27,137 --> 00:08:28,920 that's are going to be available to you 250 250 00:08:28,920 --> 00:08:31,220 and are things you're going to have to be familiar with. 251 251 00:08:31,220 --> 00:08:35,030 Finally, we have Desktop as a Service or DaaS. 252 252 00:08:35,030 --> 00:08:36,360 Now Desktop as a Service 253 253 00:08:36,360 --> 00:08:38,400 is going to provide you with a desktop environment 254 254 00:08:38,400 --> 00:08:40,320 that is accessible from the internet 255 255 00:08:40,320 --> 00:08:41,870 in the form of a cloud desktop, 256 256 00:08:41,870 --> 00:08:43,860 or a Virtual Desktop environment. 257 257 00:08:43,860 --> 00:08:46,900 A Virtual Desktop is often provided under the term VDI 258 258 00:08:46,900 --> 00:08:49,090 or Virtual Desktop Infrastructure. 259 259 00:08:49,090 --> 00:08:52,010 Now, when you purchase a Desktop as a Service product, 260 260 00:08:52,010 --> 00:08:54,260 you're going to receive a working desktop environment 261 261 00:08:54,260 --> 00:08:56,460 and any applications that you may need to use 262 262 00:08:56,460 --> 00:08:57,940 within that desktop. 263 263 00:08:57,940 --> 00:09:00,600 For example, Amazon has a VDI product 264 264 00:09:00,600 --> 00:09:02,370 known as Amazon Workspaces. 265 265 00:09:02,370 --> 00:09:03,860 With Amazon Workspaces, 266 266 00:09:03,860 --> 00:09:06,090 your organization can purchase a fully managed, 267 267 00:09:06,090 --> 00:09:08,290 persistent desktop virtualization service 268 268 00:09:08,290 --> 00:09:10,400 that allows your users to access their data, 269 269 00:09:10,400 --> 00:09:13,000 applications and resources from anywhere, 270 270 00:09:13,000 --> 00:09:15,470 anytime from any supported device. 271 271 00:09:15,470 --> 00:09:18,380 These desktops can be their Windows or Linux-based desktops, 272 272 00:09:18,380 --> 00:09:20,650 and they can be deployed to thousands of users 273 273 00:09:20,650 --> 00:09:22,460 in just a couple of minutes. 274 274 00:09:22,460 --> 00:09:23,293 In my company, 275 275 00:09:23,293 --> 00:09:26,220 we actually use a specialized Desktop as a Service platform 276 276 00:09:26,220 --> 00:09:27,920 known as Shadow PC. 277 277 00:09:27,920 --> 00:09:30,220 Now, unlike most virtual desktop services 278 278 00:09:30,220 --> 00:09:32,310 that focus on providing low power desktops 279 279 00:09:32,310 --> 00:09:33,580 for Office workers, 280 280 00:09:33,580 --> 00:09:35,860 Shadow PC focuses on providing users 281 281 00:09:35,860 --> 00:09:37,830 with a very powerful gaming PC, 282 282 00:09:37,830 --> 00:09:39,810 so they can access it from anywhere in the world, 283 283 00:09:39,810 --> 00:09:41,320 even from something like a Chromebook 284 284 00:09:41,320 --> 00:09:42,730 or an Android device. 285 285 00:09:42,730 --> 00:09:45,090 Now, why do I use a Shadow PC? 286 286 00:09:45,090 --> 00:09:47,020 Are the folks on my team big gamers? 287 287 00:09:47,020 --> 00:09:48,230 Well, they may be, 288 288 00:09:48,230 --> 00:09:50,190 but that really isn't our use case for it. 289 289 00:09:50,190 --> 00:09:51,980 Instead, we do a lot of video editing 290 290 00:09:51,980 --> 00:09:53,730 to bring courses like this one to you. 291 291 00:09:53,730 --> 00:09:55,540 And instead of having to constantly supply my team 292 292 00:09:55,540 --> 00:09:56,730 with new hardware and software 293 293 00:09:56,730 --> 00:09:58,510 to do their job as video editors 294 294 00:09:58,510 --> 00:10:00,750 and shipping those PCs all over the world, 295 295 00:10:00,750 --> 00:10:03,370 I instead opt to provide a Shadow PC. 296 296 00:10:03,370 --> 00:10:05,360 This allows them to log in with any laptop, 297 297 00:10:05,360 --> 00:10:07,960 desktop, Chromebook, tablet or mobile phone, 298 298 00:10:07,960 --> 00:10:10,080 and they can access a very powerful computer 299 299 00:10:10,080 --> 00:10:11,830 that has all the Adobe software they need 300 300 00:10:11,830 --> 00:10:14,730 to do their editing as well as doing all their other jobs. 301 301 00:10:14,730 --> 00:10:16,810 Because this gaming PC by design 302 302 00:10:16,810 --> 00:10:18,680 has a very powerful graphics card 303 303 00:10:18,680 --> 00:10:20,130 that can support rendering our videos 304 304 00:10:20,130 --> 00:10:21,730 in a short amount of time. 305 305 00:10:21,730 --> 00:10:23,880 For one monthly fee, I can give my team 306 306 00:10:23,880 --> 00:10:26,360 a constantly updated piece of superior hardware 307 307 00:10:26,360 --> 00:10:28,030 without the large upfront cost 308 308 00:10:28,030 --> 00:10:30,150 of buying all those high-end PCs 309 309 00:10:30,150 --> 00:10:32,060 and shipping them all over the world. 310 310 00:10:32,060 --> 00:10:34,210 Remember, all of these different cloud models 311 311 00:10:34,210 --> 00:10:35,380 have their own benefits, 312 312 00:10:35,380 --> 00:10:37,860 and it's important to realize what each one does. 313 313 00:10:37,860 --> 00:10:39,060 These can be NaaS, IaaS, 314 314 00:10:39,942 --> 00:10:41,840 SaaS, PaaS and DaaS, 315 315 00:10:41,840 --> 00:10:44,810 and each of those five could be provided as a public, 316 316 00:10:44,810 --> 00:10:47,410 private, hybrid or community cloud solution. 317 317 00:10:47,410 --> 00:10:49,400 It just depends on your use case. 318 318 00:10:49,400 --> 00:10:51,970 Now, one of the previous organizations I work for 319 319 00:10:51,970 --> 00:10:54,420 operate a very large private cloud variant 320 320 00:10:54,420 --> 00:10:57,080 of Desktop as a Service for their model. 321 321 00:10:57,080 --> 00:10:59,370 They had over 25,000 plus users, 322 322 00:10:59,370 --> 00:11:01,910 and they did this because it had a higher security ability 323 323 00:11:01,910 --> 00:11:02,990 'cause they could quickly patch 324 324 00:11:02,990 --> 00:11:05,320 and update all of these VDI-based solutions 325 325 00:11:05,320 --> 00:11:06,680 whenever they needed to. 326 326 00:11:06,680 --> 00:11:07,940 So it's really important for you 327 327 00:11:07,940 --> 00:11:10,440 to consider all of your options based on these things, 328 328 00:11:10,440 --> 00:11:12,560 as you're picking out a cloud solution to implement 329 329 00:11:12,560 --> 00:11:13,840 within your organization, 330 330 00:11:13,840 --> 00:11:15,493 based on your specific needs.
