WEBVTT 00:00.170 --> 00:00.740 Hey, everyone. 00:00.740 --> 00:01.830 And welcome back. 00:01.850 --> 00:07.520 Now, in today's video, we'll be looking into the lab setup for Nginx that we will be using throughout 00:07.520 --> 00:08.180 this course. 00:08.180 --> 00:09.540 So let's get started. 00:09.560 --> 00:15.860 Now, in terms for the preferred choice of Nginx installation method we'll be using or we'll be creating 00:15.860 --> 00:20.240 a new virtual machine and that virtual machine will be based on Linux. 00:20.240 --> 00:25.550 And once you have the VM ready, then we'll go ahead and install the Nginx directly on top of it. 00:25.550 --> 00:31.010 So just to revise the choices of the setup that we'll be using, the most important one is the operating 00:31.010 --> 00:31.370 system. 00:31.370 --> 00:35.810 So we will be using a red hat based OS based on version eight. 00:35.810 --> 00:41.660 So you can either make use of a CentOS eight or you can either make use of a rocky Linux eight as well. 00:41.660 --> 00:45.590 And in terms of cloud provider, we will be using Digitalocean. 00:45.590 --> 00:47.390 But this is something that is optional. 00:47.390 --> 00:51.200 You can use any cloud provider that you need or that you prefer. 00:51.230 --> 00:56.360 Now the exact operating system that we will be using in this course would be Rocky Linux eight. 00:56.390 --> 01:00.480 However, even if you're using CentOS eight, things should work perfectly well. 01:00.480 --> 01:02.490 They are very similar altogether. 01:02.490 --> 01:07.470 Now, for those who are wondering why we are making use of Rocky Linux, because this seems to be a 01:07.470 --> 01:08.340 newer name. 01:08.430 --> 01:15.030 The reason primarily because the primary support for CentOS eight CentOS is one of the most stable operating 01:15.030 --> 01:16.470 system in terms of Linux. 01:16.470 --> 01:21.690 However, the support for CentOS eight got reduced to December 2021. 01:21.690 --> 01:25.110 So this was an unexpected move by Red Hat altogether. 01:25.110 --> 01:29.490 So the stable alternative for the Red Hat is now rocky Linux. 01:29.490 --> 01:34.410 In fact, Rocky Linux is led by the founder of the CentOS project himself. 01:34.410 --> 01:40.440 So this is considered to be a very stable release, which is an alternative to that of CentOS eight 01:40.440 --> 01:43.770 specifically for that of the production environments. 01:43.770 --> 01:49.260 And this is one of the reasons why we will be using the Rocky Linux eight for our course. 01:49.260 --> 01:56.400 And if you go a bit down, this is backed by most of the popular providers like AWS, Azure, GCP, 01:56.430 --> 01:57.060 et cetera. 01:57.060 --> 02:02.490 And you will see Rocky Linux image available for all of the major providers as well. 02:02.790 --> 02:09.540 Now the second important criteria here is the cloud provider and the preferred cloud provider that we 02:09.540 --> 02:11.760 will be making use of is Digitalocean. 02:11.760 --> 02:17.430 Now, again, one of the question that comes is why Digitalocean instead of AWS or even other popular 02:17.430 --> 02:18.180 cloud providers? 02:18.180 --> 02:20.190 So let's quickly look into it now. 02:20.190 --> 02:26.160 One of the great benefits of Digital Ocean is that it is very straightforward for new users to go ahead 02:26.160 --> 02:32.910 and quickly create new servers in the cloud without much complexity and at an affordable cost. 02:32.940 --> 02:39.480 However, the primary reason why we are going to make use of digital ocean is because of the free credits 02:39.480 --> 02:41.460 that the service provider offers. 02:41.460 --> 02:47.160 So Digital Ocean offers a credit ranging from 50 to 100 USD for new users. 02:47.160 --> 02:52.860 So essentially, if you are making use of it, you can complete this entire course and even a few more 02:52.860 --> 02:56.400 other courses within the credits that you receive from it. 02:56.400 --> 02:58.080 So let's quickly look into it. 02:58.080 --> 03:03.870 Now, if you would look into the digital Ocean website, the virtual machine starts with just 5 USD 03:03.900 --> 03:04.800 per month. 03:04.890 --> 03:06.630 So let's quickly explore that. 03:06.630 --> 03:14.520 So if you just use a regular Intel SSD, one GB Ram, one Vcpu with one TB of data transfer and 25 GB 03:14.520 --> 03:21.570 of SSD disk just cost you $5 per month If you go ahead and terminate the instance before a month, you 03:21.570 --> 03:25.140 will be charged even less because this follows an hourly pricing. 03:25.140 --> 03:32.670 So even if you do not avail the credits that digital ocean offers, the overall cost is much more reduced. 03:32.670 --> 03:34.080 So this is one advantage. 03:34.080 --> 03:36.660 And the second advantage here is the credit. 03:36.660 --> 03:44.280 So if you would see currently Digital Ocean is providing 100 USD of credits altogether and in fact we 03:44.280 --> 03:50.310 are using Digital Ocean even for our other courses, specifically the Kubernetes and Splunk course where 03:50.310 --> 03:56.490 the users are deploying a highly available Kubernetes clusters completely free based on the credits 03:56.490 --> 03:58.140 that they have received. 03:58.140 --> 04:04.020 And this is the reason why we'll be using Nginx at a later part of this course when you will be using 04:04.020 --> 04:10.230 various Nginx features like load balancing reverse proxy where you need multiple servers for following 04:10.260 --> 04:10.800 the setup. 04:10.800 --> 04:13.200 The credit will prove to be very useful. 04:13.200 --> 04:19.080 Now again, one important part to remember here, this is not an advertising video for Digital Ocean. 04:19.080 --> 04:23.520 I personally use it extensively and this is one of the reasons why I recommend it. 04:23.550 --> 04:31.350 However, in case if you would want to use any other cloud provider like GCP, Azure, etcetera, you 04:31.350 --> 04:32.280 are free to use. 04:32.280 --> 04:38.310 Only primary thing that you need to note is make sure that you use a matching operating system choices. 04:38.310 --> 04:44.310 If you make use of Ubuntu altogether, then there is a certain difference in terms of the installation 04:44.320 --> 04:46.920 command in terms of the directory structure of Nginx. 04:46.920 --> 04:52.380 So the recommended operating system is CentOS eight or rocky Linux eight to begin with. 04:52.380 --> 04:55.920 So this is the high level overview about our lab setup. 04:55.920 --> 04:59.820 I'll also be posting the link of referral which you can use. 04:59.860 --> 05:05.320 To claim the credit and also get started in case if you would like to use Digitalocean. 05:05.320 --> 05:08.320 So with this, we'll conclude today's video.
