- [Instructor] In this video, I will show you how to get a free, yes, that's completely free forever, Ubuntu machine. It is from a major cloud provider
worth about $200 billion, so is not likely to
disappear any anytime soon. On screen you can see
the finished product, which is completely separate
from my local PC and network, so can not slow down on either and because it is not on my local network, you can access it from
anywhere in the world. And if I open Stacer, a
graphical performance monitor, you can see it comes
with a massive four CPUs, 24 gigabytes of memory, and almost 200 gigabytes of disc storage. If I open a text editor
on the Ubuntu instance and notepad file on my local windows PC, I can copy the contents
of the local PC file up to the Ubuntu instance even though it is running
hundreds of miles away in a data centre somewhere. So after this short introduction, I will show you how it was all done. ("Lights - Alternative
Version" The Places) ("Lights - Alternative
Version" The Places ends) ("Trip to Roma" Swirling Ship) If you key into Google Search the words Oracle Cloud Free Tier and then select the first link, it will take you to this page. If I just scroll down, I can show you what is included
in this always free offer. ("Trip to Roma" Swirling Ship continues) Yes, there are extra services that are available for 30 days, but the resources I am showing
you here are always free. So that's a massive 24
gigabytes of memory, four arm-based CPUs, and 200 gigabytes of storage. So to get that, if I scroll back up, you can see a button
labelled Start for Free, which, when pressed, starts
the registration process. There may be some basic
verification processes to complete as part of this signup process as it is just trying to
ensure you're a real human and not an internet bot
trying to abuse the offer by getting many individual
accounts with lots of resources. So after signing up, you will be taken to this webpage, and as you can see at
the top of the screen, there is a purple banner explaining that you are currently on the free plan. And unless you specifically
upgrade to a paid account, which we are not going to do, you will never be charged. As this topic has generated many questions and comments on other YouTubers' channels, like, why do some companies offer these free forever resources, et cetera? I have put a link to one of their question and answer videos in
the YouTube description that hopefully answers
any questions you have. ("Trip to Roma" Swirling Ship continues) I select the option to
create a VM instance. I give the instance a name. I move down to the image and
shape box and select edit. I change the image to Canonical Ubuntu, ("Trip to Roma" Swirling Ship continues) then operating system version 20.04, and press the select image button. ("Trip to Roma" Swirling Ship continues) I change the shape from
the default AMD to Ampere. I select the default size and increase it to use all four CPUs. A yellow warning box
appears just letting us know we are at the limit of this
free account for CPUs now. So we ignore it and press create. ("Trip to Roma" Swirling Ship continues) For SSH key, we select paste key. At this point, I stop and download and install the Windows PuTTY SSH client importantly from the official website. It includes an application
called PuTTY General, which is an SSH key generator. So I open that and generate an SSH key. I then copy the onscreen public key part and paste it into the
website's SSH key box. Before pressing the create button, I increase the boot volume size, so it uses all 200 gigabytes. When I do so, I see the yellow warning box again, simply indicating that I am using all 200 gigabytes of space. So I just ignore it and press create. At this point, I get an error saying that the data centre, also known
as an availability domain, does not have the resources
available at the moment to satisfy the request. Normally, it only to takes
a few days to restock. But rather than wait, I simply scroll to the top and change where this
server is to be placed in another data centre or availability zone in this region. ("Whistling All the
Way Down" Assaf Ayalon) I then press create, and because this availability zone does have the requested resources, it starts to provision the server. This provisioning can take up to a minute, so in the meantime, I return to PuTTY Gen and save the private half of
the key that we will need later to connect to the
provision server via SSH. ("Whistling All the Way
Down" Assaf Ayalon continues) Now, the server has finished provisioning, we need to let our RDP
remote control traffic, which is on port 3,389 through the Oracle's
console-based firewall through to the instance as we will be using it in a
minute to display its desktop. So to do that, I select the instance's subnet, then its default security list ("Whistling All the Way
Down" Assaf Ayalon continues) to which I add a new ingress rule with the information you can
see me enter the onscreen form. ("Whistling All the Way
Down" Assaf Ayalon continues) And when finished, I go back ("Whistling All the Way
Down" Assaf Ayalon continues) to connect to the instance
I have just created because as yet, I haven't put
XRDP in the desktop on it. I open PuTTY, the Windows SSH client. ("Whistling All the Way
Down" Assaf Ayalon continues) For host name, I enter Ubuntu, an @ sign, followed by the instances IP address. ("Whistling All the Way
Down" Assaf Ayalon continues) I then select the SSH auth tab and browse to the private
part of the SSH key that I created and saved
earlier in PuTTY Gen. ("Whistling All the Way
Down" Assaf Ayalon ends) This part is optional. I browse to the appearance tab and change to a bigger font
that is both easier to read and displays better on this video. ("Come Back Home" Assaf Ayalon) Now, before I open the connection, I return to the main tab. ("Come Back Home" Assaf Ayalon continues) Name and then save the settings. ("Come Back Home" Assaf Ayalon continues) Only now do I start the connection. ("Come Back Home" Assaf Ayalon continues) As this is the first time
this machine's SSH client has connected to this instance, it just gives a warning. I accept it and proceed
with the connection. On screen you can see my
open SSH connection window from a moment ago and below it, the five
configuration commands that I copied out of
the YouTube description. If I zoom into the SSH window, while I cut and paste each, you can more easily see
the typical response when each are run. This first command
updates the repositories so they point at the latest
version of each module and then upgrades any out of date module so as to include all known bug fixes and security patches. ("Come Back Home" Assaf Ayalon continues) The second command instals
the Ubuntu Desktop, the XRDP remote control software, and the Stacer performance
graphical monitor, which you saw in the introduction. And I have found very useful as it summarises any instance's CPU, memory, and disc usage. This installation command normally runs for five or 10 minutes, but through the magic of video editing, it will only take a few seconds. ("Come Back Home" Assaf Ayalon continues) All Oracle instances come with a set of iptables firewall rules that block most ports on the instance, but we are already using the console-based firewall for that. And maintaining two
firewalls can be complex and I would only normally suggest it when the instance has
to be very, very secure. As a result, to remove this instance's
unnecessary extra firewall that is just adding complexity, this command firstly copies all existing instance
iptables firewall rules to a backup file and then truncates the file to zero size, thereby removing them from
when the instance is rebooted. This command removes the
policy that causes the annoying and frequent window that
appears on the desktop requesting password authorization
to create a colour device every five minutes. This final command sets the
password for the Ubuntu user that we will be using to connect via RDP. It is very important that this
password is complex, long, so over 10 characters in length and not found in a dictionary to prevent this instance being susceptible to brute force attacks. An example of the password
I'm using is on screen. And that's all five
configuration commands completed. All we do now is reboot it to ensure they're all fully in effect. The server is now ready for use. All we have to do now is connect to it. I open the Remote Desktop
Connection Windows application, copy and paste the instance's IP address from the Oracle website
into the application. ("Japanika" Swirling Ship) Enter the username as Ubuntu, tick the box that allows
me to save credentials as unlike the typical XRDP log on screen, the resultant screen will allow me to paste in the complex password. I go to the resources tab and ensure only clipboard is ticked. If this video proves popular, I will look at how it can be improved, so local drive mapping also works, but for now, it doesn't. I return to the main tab. Here I do have an option to save all these settings in a file. However, for now, I just connect. ("Born Twice" Eyal Raz) I get the complex password, which I have recorded and proceed to copy and paste it into the credentials window. ("Born Twice" Eyal Raz continues) When connected, I proceed through the welcome
screens onto the main desktop ("Born Twice" Eyal Raz continues) where the only change I
make is under settings, privacy, lock screen where I disable everything. That is because if this
instance were to lock, it can be problematic connecting to it. Finally, I find and start the
Stacer performance monitor ("Born Twice" Eyal Raz continues) to prove the instance
can see all the CPUs, memory, and disc. ("Born Twice" Eyal Raz continues) And that's it, the
machine is ready for use. On screen, you will find a video showing how to deploy a Windows
server 2019 disc image and below it, a video I made showing how I create it in Kali Linux VPS from the official Kali ISOs. And if you want to see
