In this video which happens to be the last one in the introduction
of Lennox section. We're going to explore where you will find
Lennox and what it is used for.
Here. I have Cherry Picked six common use
cases where you will find Linux as the dominant player.
The first use case is cloud computing.
Linux is the main OS in Cloud providers like AWS and
Google Cloud since Lennox is secure easy
to manage and reliable is the perfect choice for cloud
providers to build their infrastructure on
we'll explore cloud computing in more detail in the next section.
Another area where Linux is dominant is the internet.
Just about every website you visit is being served up by a Lennox
hosts. In fact, according to ZDNet 500 of
the top websites in the world run Lennox.
This includes sites like Google Amazon Instagram and
Twitter.
So if you need to host a website, you should run
it on Linux.
The next market area where Linux is dominant is mobile.
Approximately 85% of all the smartphones across the
world running version of Linux. Most of these
devices are Android. There are other mobile platforms like
Libre and pine phone as well, but they do not
have the same market share as Android.
However, there is an interesting fact about Libre and
pine not only do they run open source software, but
they also run Open Source Hardware as well. The internet
of things or iot has invaded
our homes and personal life. You may have
a video doorbell smart thermostat or voice activated
assistant.
If you do you're controlling your home with Linux because of
lennox's Versatility in small size is a
natural fit for all these devices.
The next use case is super computing.
Linux is the Undisputed king of supercomputers.
Twice per year the top 500 list of supercomputers is released.
As of November 2022 Linux accounted
for 448 out of 500 of
these super machines. The fastest supercomputer in
the world is called Frontier.
It runs a Lennox based OS called hpe cray and
clocks in a whopping 1,685.65 petaflops.
Last but not least is virtualization.
There are a few virtualization Technologies like Colonel based virtual
machine, which is also known as KVM Zen
and containers the two most popular right now
are KVM and containers.
KVM is a Linux module that makes virtualization possible for
many Cloud providers while the container movement
started in and is dominated by Lennox.
Chances are if you created a virtualized instance in
the cloud today that instances running on a Linux host.
Okay, let's do a recap about the few main areas where
Lennox is used. The first is Lennox runs
the internet the most visited sites of the world are served
on Lennox.
The second is the cloud runs on Linux.
Every major cloud provider relies on Linux
to be the foundation of their infrastructure and business.
And finally Linux dominates the
container movement containers are the preferred
way to deliver software today in Linux is the best native way
to do that.
Okay, we have come to the end of introduction Linux in
the next section. We will begin our overview of
devops in Cloud fundamentals and apply some of this Linux
knowledge.
See you soon.
