1 00:00:00,000 --> 00:00:01,290 In this section of the course, 2 00:00:01,290 --> 00:00:04,050 we're going to discuss the cloud and the data center. 3 00:00:04,050 --> 00:00:06,600 So it's now time for us to put our heads in the cloud. 4 00:00:06,600 --> 00:00:07,770 Well, not really. 5 00:00:07,770 --> 00:00:09,750 What I mean to say is that in this section of the course, 6 00:00:09,750 --> 00:00:11,640 we're going to be discovering cloud computing, 7 00:00:11,640 --> 00:00:13,830 virtualization, and the data center. 8 00:00:13,830 --> 00:00:15,780 So in this section, we're going to be focused solely 9 00:00:15,780 --> 00:00:17,910 on domain 1 networking concepts, 10 00:00:17,910 --> 00:00:20,280 but we'll be covering two different objectives. 11 00:00:20,280 --> 00:00:21,810 Objective 1.3 states, 12 00:00:21,810 --> 00:00:23,670 you must be able to summarize cloud concepts 13 00:00:23,670 --> 00:00:25,380 and connectivity options. 14 00:00:25,380 --> 00:00:27,180 We'll also cover objective 1.8, 15 00:00:27,180 --> 00:00:28,770 which states that you must be able to summarize 16 00:00:28,770 --> 00:00:31,830 evolving use cases for modern network environments. 17 00:00:31,830 --> 00:00:34,050 Now first, we're going to be looking at a general overview 18 00:00:34,050 --> 00:00:36,000 of cloud computing, including what it is 19 00:00:36,000 --> 00:00:37,410 and what it's used for. 20 00:00:37,410 --> 00:00:39,780 Then we'll discuss the different cloud service models, 21 00:00:39,780 --> 00:00:41,310 including infrastructure as a service, 22 00:00:41,310 --> 00:00:44,010 platform as a service, and software as a service. 23 00:00:44,010 --> 00:00:45,960 Next, we'll be learning all about the different types 24 00:00:45,960 --> 00:00:48,480 of cloud deployment models, including public clouds, 25 00:00:48,480 --> 00:00:51,360 private clouds, community clouds, and hybrid clouds. 26 00:00:51,360 --> 00:00:52,680 After that, I'm going to show you 27 00:00:52,680 --> 00:00:54,360 how you can begin to use the cloud yourself 28 00:00:54,360 --> 00:00:56,940 by installing a simple service like Amazon light sale, 29 00:00:56,940 --> 00:00:59,010 in order to create your own virtual Linux server 30 00:00:59,010 --> 00:01:01,320 in the cloud, and you can use it while you're studying 31 00:01:01,320 --> 00:01:04,080 for your certifications now or in the future. 32 00:01:04,080 --> 00:01:06,390 Then we're going to be covering cloud connectivity 33 00:01:06,390 --> 00:01:07,530 by discussing how you can reach 34 00:01:07,530 --> 00:01:09,720 into the cloud-based services to configure them, 35 00:01:09,720 --> 00:01:12,150 work with them and manage them over time. 36 00:01:12,150 --> 00:01:13,980 Next, we're going to look at cloud security, 37 00:01:13,980 --> 00:01:16,170 including how you can use virtual private clouds 38 00:01:16,170 --> 00:01:17,790 to better protect your sensitive data 39 00:01:17,790 --> 00:01:19,920 within the cloud provider's environment. 40 00:01:19,920 --> 00:01:22,500 After that, we're going to explore network virtualization 41 00:01:22,500 --> 00:01:24,960 and how common network devices like switches, routers, 42 00:01:24,960 --> 00:01:27,810 and firewalls have become simply another application 43 00:01:27,810 --> 00:01:29,100 that you can install and use 44 00:01:29,100 --> 00:01:31,110 when you're operating inside the cloud. 45 00:01:31,110 --> 00:01:34,470 Then we'll discuss SDNs or Software Defined Networks 46 00:01:34,470 --> 00:01:36,420 and how they're used to separate out the three planes 47 00:01:36,420 --> 00:01:37,950 used in networks and abstract them 48 00:01:37,950 --> 00:01:39,300 from the underlying devices 49 00:01:39,300 --> 00:01:41,070 that are actually performing those functions 50 00:01:41,070 --> 00:01:42,870 in order to provide us with a more scalable 51 00:01:42,870 --> 00:01:46,260 and more efficient way of operating our networks at scale. 52 00:01:46,260 --> 00:01:49,080 Next, we're going to cover Software Defined Wide Area Networks 53 00:01:49,080 --> 00:01:50,940 or SD-WANs and how they're used 54 00:01:50,940 --> 00:01:52,950 within our cloud-based environments. 55 00:01:52,950 --> 00:01:55,380 After that, we'll take a look at VXLAN, 56 00:01:55,380 --> 00:01:58,140 which is known as the Virtual Extensible Local Area Network, 57 00:01:58,140 --> 00:02:00,210 and this is essentially a new and improved version 58 00:02:00,210 --> 00:02:01,890 of a virtual local area network, 59 00:02:01,890 --> 00:02:03,270 and it's a concept that's heavily used 60 00:02:03,270 --> 00:02:05,850 in our highly scalable cloud-based networks. 61 00:02:05,850 --> 00:02:09,030 Then we're going to be discussing SASE and SSE, 62 00:02:09,030 --> 00:02:11,130 which are the Secure Access Secure Edge, 63 00:02:11,130 --> 00:02:12,990 and then Security Service Edge. 64 00:02:12,990 --> 00:02:14,940 Both of these concepts are going to be used heavily 65 00:02:14,940 --> 00:02:17,130 in our cloud-based networks all the time. 66 00:02:17,130 --> 00:02:19,080 So it's important that we spend a little bit of time here 67 00:02:19,080 --> 00:02:21,330 covering both of these related concepts. 68 00:02:21,330 --> 00:02:22,830 Finally, we're going to take a short quiz 69 00:02:22,830 --> 00:02:24,840 to see what you learned during this section of the course 70 00:02:24,840 --> 00:02:26,220 and review your answers to make sure 71 00:02:26,220 --> 00:02:27,630 you know why the right answers were right 72 00:02:27,630 --> 00:02:29,100 and the wrong answers were wrong. 73 00:02:29,100 --> 00:02:31,590 So if you're ready, let's get started with our coverage 74 00:02:31,590 --> 00:02:32,880 of the cloud and the data center 75 00:02:32,880 --> 00:02:34,380 in this section of the course.
