1 00:00:02,070 --> 00:00:04,520 Now let's start at the basics. 2 00:00:04,520 --> 00:00:08,440 How can we publish our website to the world? 3 00:00:08,440 --> 00:00:12,400 Well, for this, your website must be hosted 4 00:00:12,400 --> 00:00:15,460 on some remote machine as it's called. 5 00:00:15,460 --> 00:00:16,920 Now, what does that mean? 6 00:00:16,920 --> 00:00:20,760 It simply means that we have our website code 7 00:00:20,760 --> 00:00:24,810 and our website code lives on our local machine right now, 8 00:00:24,810 --> 00:00:29,240 which typically doesn't accept external HTTP requests. 9 00:00:29,240 --> 00:00:31,630 And we don't want our local machine 10 00:00:31,630 --> 00:00:34,840 to accept external HTTP requests 11 00:00:34,840 --> 00:00:37,293 as this would pose a security issue. 12 00:00:38,170 --> 00:00:42,060 Instead, we wanna keep our code on our local machine 13 00:00:42,060 --> 00:00:44,100 and work on it and test it 14 00:00:44,100 --> 00:00:47,650 as long as we are, well, developing the website. 15 00:00:47,650 --> 00:00:49,070 But of course, at some point, 16 00:00:49,070 --> 00:00:52,080 we wanna expose our website to the world. 17 00:00:52,080 --> 00:00:54,440 Because we wanna enable visitors, 18 00:00:54,440 --> 00:00:58,550 people from all over the world to view our website 19 00:00:58,550 --> 00:01:01,180 and they can't access our website code 20 00:01:01,180 --> 00:01:03,490 as long as it's on our local machine. 21 00:01:03,490 --> 00:01:06,400 This is not possible because as mentioned, 22 00:01:06,400 --> 00:01:09,420 our local machine typically does not allow 23 00:01:09,420 --> 00:01:11,723 external HTTP requests. 24 00:01:12,580 --> 00:01:16,530 Now I will say you could configure your local computer 25 00:01:16,530 --> 00:01:20,740 and network such that it does allow external requests 26 00:01:20,740 --> 00:01:22,960 because in the end, the remote machines 27 00:01:22,960 --> 00:01:25,280 we're going to move our code to later 28 00:01:25,280 --> 00:01:29,050 are just regular machines that are configured such. 29 00:01:29,050 --> 00:01:31,500 But unless you really know what you're doing, 30 00:01:31,500 --> 00:01:34,830 you don't wanna fiddle with your local computer 31 00:01:34,830 --> 00:01:38,580 or network configuration to allow external visitors 32 00:01:38,580 --> 00:01:40,730 because as mentioned before as well, 33 00:01:40,730 --> 00:01:44,023 this can quickly introduce security problems. 34 00:01:45,180 --> 00:01:48,090 So therefore, instead, the goal is to deploy, 35 00:01:48,090 --> 00:01:52,740 which basically just means to upload our website code 36 00:01:52,740 --> 00:01:56,430 onto some remote machine that is configured 37 00:01:56,430 --> 00:01:59,930 to take external HTTP requests. 38 00:01:59,930 --> 00:02:02,230 So we wanna have our deployed website code 39 00:02:02,230 --> 00:02:04,590 on such a remote machine. 40 00:02:04,590 --> 00:02:06,030 And that remote machine 41 00:02:06,030 --> 00:02:07,900 and therefore the code on that machine 42 00:02:07,900 --> 00:02:11,450 will then be accessible by external visitors 43 00:02:11,450 --> 00:02:13,830 and therefore people from all over the world 44 00:02:13,830 --> 00:02:16,023 will be able to see our website. 45 00:02:17,660 --> 00:02:22,200 Now, this remote machine is typically not configured by us 46 00:02:22,200 --> 00:02:24,890 because it's not an easy task. 47 00:02:24,890 --> 00:02:25,723 You could do it 48 00:02:25,723 --> 00:02:29,160 if you are an experienced network administrator. 49 00:02:29,160 --> 00:02:31,840 You could definitely build your own computer, 50 00:02:31,840 --> 00:02:33,570 configure it correctly, 51 00:02:33,570 --> 00:02:36,630 connect it to a network and configure that as well, 52 00:02:36,630 --> 00:02:38,420 and then build your own computer 53 00:02:38,420 --> 00:02:40,450 that is exposed to the world. 54 00:02:40,450 --> 00:02:42,690 But typically, we don't do that 55 00:02:42,690 --> 00:02:45,270 because it's definitely not easy, 56 00:02:45,270 --> 00:02:47,660 but instead easy to mess up. 57 00:02:47,660 --> 00:02:50,640 Because if we would wanna do that on our own, 58 00:02:50,640 --> 00:02:52,580 we, of course, would have to take care 59 00:02:52,580 --> 00:02:54,690 about having proper hardware, 60 00:02:54,690 --> 00:02:56,720 about installing all the software 61 00:02:56,720 --> 00:02:58,440 and configuring all the software 62 00:02:58,440 --> 00:03:00,930 that might be needed behind the scenes. 63 00:03:00,930 --> 00:03:03,860 We would have to deal with the network configuration 64 00:03:03,860 --> 00:03:07,400 and with exposing the proper ports on our machine 65 00:03:07,400 --> 00:03:11,250 so that external requests can reach those ports. 66 00:03:11,250 --> 00:03:14,980 And, of course, we would have to deal with security issues. 67 00:03:14,980 --> 00:03:18,540 So definitely nothing we wanna do on our own typically. 68 00:03:18,540 --> 00:03:22,200 And instead, there are dedicated hosting providers, 69 00:03:22,200 --> 00:03:26,080 companies out there which sell hosting, 70 00:03:26,080 --> 00:03:29,730 so the offering of such pre-configured machines 71 00:03:29,730 --> 00:03:30,793 as a service. 72 00:03:31,660 --> 00:03:34,630 And therefore, we can just pay those providers 73 00:03:34,630 --> 00:03:37,970 to get access to a readily configured machine 74 00:03:37,970 --> 00:03:40,750 onto which we can upload our code. 75 00:03:40,750 --> 00:03:43,460 And thankfully, there are even providers 76 00:03:43,460 --> 00:03:45,250 that let us get started for free 77 00:03:45,250 --> 00:03:47,770 and we'll have a look at such an example provider 78 00:03:47,770 --> 00:03:50,030 throughout this course section. 79 00:03:50,030 --> 00:03:51,800 Though I will say already, 80 00:03:51,800 --> 00:03:54,260 if you Google for a hosting provider 81 00:03:54,260 --> 00:03:58,690 or something like host a website, 82 00:03:58,690 --> 00:04:02,520 you will find dozens and hundreds of results, 83 00:04:02,520 --> 00:04:04,970 advertisements and regular results 84 00:04:04,970 --> 00:04:07,480 of hosting providers you could use 85 00:04:07,480 --> 00:04:09,970 and of blog articles and comparisons 86 00:04:09,970 --> 00:04:12,920 that walk you through different hosting providers. 87 00:04:12,920 --> 00:04:16,230 And, of course, it's way beyond the scope of this course 88 00:04:16,230 --> 00:04:18,779 to compare all those hosting providers. 89 00:04:18,779 --> 00:04:21,860 There basically is an infinite amount of those providers. 90 00:04:21,860 --> 00:04:23,110 But instead it's up to you, 91 00:04:23,110 --> 00:04:26,060 if you're serious about deploying a website 92 00:04:26,060 --> 00:04:28,230 to go through a couple of different options 93 00:04:28,230 --> 00:04:31,280 and find out which option you prefer. 94 00:04:31,280 --> 00:04:33,410 Of course, all those hosting providers 95 00:04:33,410 --> 00:04:35,730 typically allow you to host a website, 96 00:04:35,730 --> 00:04:38,770 but then some providers have some extra services. 97 00:04:38,770 --> 00:04:40,960 Some providers give you more control, 98 00:04:40,960 --> 00:04:45,180 whereas others gives you less control and so on. 99 00:04:45,180 --> 00:04:47,810 You can, of course, always switch a hosting provider 100 00:04:47,810 --> 00:04:51,380 even after you chose one if you wanna migrate your website 101 00:04:51,380 --> 00:04:53,463 to a different provider in the future. 102 00:04:54,320 --> 00:04:57,010 But for the moment, that's it about hosting providers. 103 00:04:57,010 --> 00:05:00,140 We will later use one together in this course section, 104 00:05:00,140 --> 00:05:01,690 but before we do that, 105 00:05:01,690 --> 00:05:04,230 we'll have to prepare our website a little bit 106 00:05:04,230 --> 00:05:05,970 and we'll have to learn a bit more 107 00:05:05,970 --> 00:05:09,440 about choosing a proper hosting provider 108 00:05:09,440 --> 00:05:12,960 because it turns out that there is one important difference 109 00:05:12,960 --> 00:05:14,213 you should be aware of.
