All right guys.
Now you understand the main idea behind using your dollar machines and it is that every doll machine
has its own guest operating system.
That of course may differ from under a lion operating system that is used on Main Computer where your
doll machines are running and also usually every beautiful machine has its own dedicated resources like
the Dickey the amount of memory the decayed the sippy use and dedicated disk space.
And no let me do for you quick demo and show you how I personally use your doll machines for development
and for recording of those courses.
All right I use wheelbarrow fuels.
It is hyper of user for Mac OS and basically at the end of a previous lecture I have shown you that
I currently run three different machines Mac OS or wound to end windows.
Of course usually I don't run those of you little machines in parallel and sometimes I stop to help
them and run on the single.
For example Mac OS or when I need for example Windows little machine I start to eat and stop macros
but it is of course possible to run all of them simultaneously but I'll show you just in the moment
of what will happen if I'll start all of them simultaneously.
My Mac.
Also we'll be actually almost out of memory.
All right.
Let me go to this page where I have actually least of your dole machines that I'm currently running.
It is Mac also gain windows and or born to and look me.
We could demonstrate your settings for example of this Mac or your dole machine.
Go to settings and The here goal for example two processors and memory and you'll see that this particular
of your dole machine has a dual process of course assigned and also it has eight gigabytes of RAM.
There are also advanced options like enable hyper user applications in this machine enable called profiling
applications and so on with this option for example I am able to create virtual machines inside of this
make most of your adult machine all right let's go back for example to configuration of disk and here
you see that I have assigned to 46 gigabytes of disk storage to this particular digital machine and
all files for this particular review machine are stored in this DMD gay file.
Let me actually quickly go to this BMD gay file and so its structure and basically accept this IBM to
file.
There are a bunch of other files.
Let me show and find finder files for this.
Michael's audio machine show package contents.
And here you may see at least of files for this particular audio machine.
And basically there are a bunch of different configuration files cache files log files and so on.
But the main files are here.
This VM decay file and this one actually I am running here.
Catalina Mac also operating system and it actually uses two different disk drives one for operating
system and second for remaining files.
And this way here I see two different vindictive files.
Also it is possible to create the so-called snapshots of your machine and you'll see that the delta
is single snapshot that actually also takes some amount of this size.
It is almost 9 gigabytes in size.
It is possible to create multiple snapshots and go back to a particular moment in time using snapshots.
All right.
That's how disk looks like for this particular digital machine.
And total size of Mac OS your dollar machine is 65 gigabytes.
It is of course larger than specified here in settings.
Let me go to settings back and actually again limited that will set for these several dollar machine
is 46 gigabytes.
All right.
Let me also show you other settings like network adapter you are able to add multiple adapters if you
want but here you see option share with my Mac.
And in such case the adult machine will share IP address of my main computer.
Next you are also able to set the same configuration parameters for display and so on.
All right that's settings for this particular bill machine.
I could also quick to show your settings for these the windows of your machine and I have configured
for it for gigabytes of RAM and also to process our calls.
All right.
But now let me demonstrate to you how many resources are actually used at the moment at my main computer.
And for that let me open up activity monitor and go to memory here and filter by we own barrow and actually
you'll see main view of our fusion process.
Here it is.
It takes almost 300 megabytes of frame but also you'll see three different on where the mix process
is.
This one this one and this one.
And basically at the moment every of those processors is responsible for running off separate to your
toll machine.
And I have just shown you that I have allocated 80 Goodbye It's a friend to Mac.
Also you told machine and that's way here you see it.
This process that actually takes this amount of RAM Ed gigabytes of RAM.
And here next you'll see windows we told machine and it takes four gigabytes of RAM and last one is
a.
And I feel obligated to adjust to gigabytes of RAM is brute DNA also let me go to CB you tap and also
on this step you'll see three different processes that are currently using some part some percentage
of my main CB You for example this one is using the moment 16 percent of my main CPO.
That's how it looks in terms of resources consumption.
And basically if I have a look again at the memory you should see that my physical amount of memory
on this computer is 16 gigabytes and almost 13 gigabytes of RAM are currently utilized by those three
different your dollar machines.
That's why it means that I am not able to start three additional such kind of your dollar machines because
my computer will be simply out of memory.
All right.
Also let me demonstrate quickly that I have also access to yes.
I sativa that is actually hyper use them that is installed directly onto the server and it is actually
a remote Sarah.
And here on this cetera you might also see some of your dollar machines that are present day.
For example I am able to access one of your dollar machine and I am able to open it up and log into
it remotely same.
I can do wheels any hours or doodle machines on this computer.
All right.
Let me also show you that you are also able to perform different management tasks.
So with every of your dollar machine for example I could suspend your dollar machine I could stop it
I could do reloaded I could create a full clone and of course you are able to move your dollar machine
from one computer to another.
And on the production services like Bill Murray Yes excite Sarah as you are able to automate all those
tasks so you are able to create the let's say 10 clones from particular of your time machine you could
move all machines from one set of auto NAS or you can scale machines and so on.
It is really really nice production solution.
All right.
That's all for this demo.
I hope you liked it.
And the main idea that they wanted to transfer to you is that every viewer doll machine trust has its
own guest operating system.
And second has its own resources.
And I have shown you that if I allocate particular amount of RAM to particular of your time machine
then this amount will be forever a reserve at my main computer forever.
I mean while your machine is running as soon as I stop it.
Of course those are sources will be freed up.
It is also possible to create little machines that actually share resources share your resources and
share a ram and such approaches are very often used by hosting providers like Amazon and Google Cloud
or digital ocean and you are able to buy IIs or digital machine with dedicated resources dedicated the
Utah super you dedicated memory or you are able to buy so-called beautiful machines with shared resources
and share Ram and the CBO with hours are brutal machines socially or machines are usually much cheaper
than machines with dedicated resources.
Let me basically quickly show you that and let me go for example to digital ocean and here gold two
products and droplets every asset over here is gold actually droplet and if your scroll down a bit you
could see that there are so-called standout droplets and they share CPO with our droplets and are dedicated
CPO droplets that tell 100 percent dedicated viewer told CBS along equals the balance of the memory.
All right.
That's how it looks at hosting services and to gain most the company's most the hosting services are
using nowadays view adult salaries instead of dedicated salaries and almost no one uses so-called bare
metal or dedicated salaries.
I mean Sarah was physical mammary physical CPR resources and so on because of all advantages of using
multiple machines they could be easily scaled migrate that the corporate glommed and so on.
All right guys I hope that you enjoyed this quick overview of my setup and now you completely understand
what is your thought machine and what are advantages of using the auto machine.
Let's not proceed and next let me talk about architecture of Docker and advantages of using Docker.
And of course about these advantages of using Docker.
I'll see you next.
Bye bye.
