🎤 Bass in Morning Recordings and Freshers in DevOps
The speaker humorously notes how recording videos in the morning deepens their voice, comparing it to Samuel Jackson. They then pose a question to viewers about the common belief that freshers cannot secure jobs in DevOps. While acknowledging this as a widespread claim, they point out that people still manage to land DevOps roles and promise to return to this topic later in the video.
🚀 Introduction to the DevOps Engineer Roadmap
The speaker begins the roadmap to becoming a DevOps engineer, stressing that this guide will be precise and practical. While DevOps is often described as a 'mindset' or 'cultural shift,' the speaker simplifies the role: moving code from a developer’s local environment to production, ensuring uptime and functionality for clients. This involves continuous integration and maintenance but centers around deploying and managing code across different environments.
💻 Programming Skills and Application Management in DevOps
The speaker explains that DevOps engineers do not need to focus heavily on programming, though some knowledge is helpful. They emphasize that understanding how to read and deploy code is more important than writing business logic. Regardless of application complexity, DevOps engineers approach tasks like deploying code, managing servers, and setting up databases similarly. While programming skills are an advantage, the speaker encourages learners to focus on tools and infrastructure rather than coding itself.
🐧 Mastering Linux for DevOps
The first major step in becoming a DevOps engineer is to become proficient in Linux, with a recommended two months of dedicated learning. The speaker highlights the importance of Linux knowledge across different cloud platforms (AWS, GCP, Azure) and encourages installing Linux as the main operating system for faster learning. The Linux foundation is essential, covering topics like disk management, networking, and namespaces, which are crucial for understanding containers like Docker.
🔧 GIT, YAML, and Their Role in DevOps
Once Linux proficiency is achieved, the next step is mastering Git, an essential version control tool used frequently by DevOps engineers. The speaker advises spending time on Git concepts, followed by learning YAML for infrastructure configuration. YAML is important for defining cloud infrastructure without programming and is a key language in DevOps. Understanding these tools will simplify the process of deploying and managing infrastructure.
☁️ Cloud Skills and AWS Focus
After mastering Git and YAML, the speaker recommends focusing on cloud platforms, specifically AWS. They explain that AWS offers the most widely-used services, making it a valuable skill in the job market. The speaker advises real-world practice by spinning up servers in AWS, overcoming the fear of running up high bills, and learning cloud scaling (both horizontal and vertical). AWS certifications can also add credibility and boost a DevOps candidate’s resume.
📦 Docker, Kubernetes, and Cloud Independence
Next, the speaker introduces Docker and Kubernetes, explaining how Docker containers applications for deployment and Kubernetes manages containers across servers. Kubernetes is especially valued for making deployments cloud-independent, allowing the same configurations to be used across AWS, GCP, and other cloud providers. Mastering these tools positions a learner well into the DevOps journey, preparing them to manage scalable, reliable infrastructures.
🛠 Advanced Tools: Terraform, Ansible, CI/CD Pipelines
With a strong foundation, the speaker suggests learning advanced tools such as Terraform, Ansible, GitHub Actions, and Argo CD for automating infrastructure. These tools allow DevOps engineers to define infrastructure as code and automate deployments and scaling. While these tools are essential, the speaker cautions against falling into 'tool hell,' focusing instead on understanding daily DevOps workflows, such as containerizing apps and ensuring they are scalable.
🔍 Avoiding Tool Hell and Simulating Real DevOps Workflows
The speaker warns about the trap of learning too many tools without understanding their practical applications. They stress that a good DevOps engineer focuses on understanding real workflows, like making applications scalable and monitoring them, rather than mastering every possible tool. Success in DevOps means being efficient and unnoticed, as seamless operations suggest nothing is going wrong. The speaker emphasizes practical experience over tool collection.
🛠 Gaining Experience and Proving Skills in DevOps
Addressing the challenge of landing a job as a fresher in DevOps, the speaker advises taking proactive steps to gain experience through self-directed projects. By sharing code on platforms like GitHub and showcasing work with YAML and cloud infrastructure, candidates can demonstrate skills to potential employers. The speaker promises to provide use cases and examples in future videos, encouraging learners to build a portfolio of hands-on experience.
📈 Final Thoughts and Encouragement for DevOps Learners
The speaker concludes by reaffirming the goal of the video: providing a clear and precise roadmap to becoming a DevOps engineer. They invite viewers to engage through comments or reach out on social media with questions. By following this roadmap and gaining practical experience, aspiring DevOps engineers can confidently approach job opportunities. The speaker also invites feedback and encourages subscriptions for more in-depth guides in the future.

Transcripts
the moment I record a video early in the
morning it adds too much of bass I sound
like Samuel Jackson okay here's a quick
question for you let me know in the
comments section have you ever heard
that nobody is giving jobs to fresher in
the devops industry if that is true how
come anybody is ever cracking a job in
the devops industry and here's a fact on
top of this nobody likes to give a job
to fresher even for web development
mobile development or anything else as a
matter of fact I'll come back on to this
one and we'll talk in depth of this
later on in this video first let's go
ahead and get started with the road map
to become a devops engineer hey there
everyone atheish here back again with
another video and in this video I'll
give you a precise road map to become a
devops engineer so that if you're
learning on your own or maybe following
some other resources as well you can
actually find out that what I need to
learn and what order I need to learn
it's not a vague guide which includes
everything that is possibly there in the
devops but a precise roadmap that can
give you on some path I am very much
sure that you have heard about the term
devops and you are pretty much
interested in that and you have heard
things like devops is a mindset devops
is more like a cultural thing in your
company I agree to some extent but it's
not about the cultural activities that
somebody is hiring you for the devops
yes it's great to sound but the whole
idea and a shortcut hacky definition of
devops is people write code on the
localhost it's the devops engineers
responsibility to move that code into
the production and make sure it is
always available to the client that is
the gist of it and that's what the
devops engineer do in the day-to-day
life yes it includes a lot of things
about maintenance updates continuous
integration a lot of things but that's
the whole idea the journey is from The
Local Host to the production environment
now the first obvious question is what
should I know already in advance to
become a devops engineer do I need to
learn ton of programming the good thing
a lot of people love that is that devops
doesn't require you to have too much
understanding of programming you should
definitely be able to read the code and
get an overview what does this code look
like and what it's going to do what I
need to install but you don't need to
write business Logics that's the job of
developers not the devops for a devops
engineer any application that is a basic
to do which is adding a to-do's and
adding them into the database maybe
postgres MySQL or mongodb is exactly
same as some complex application which
is processing too much of data and then
putting it into the database yeah surely
there could be difference in how the
servers are what the configuration is
but for us it's devops engineer it's
exactly the same application we need to
move it on to the server spin up few
machines and put up a database behind it
surely if you have programming
experience you are going to thrive a lot
in the world of devops because you
understand the code a lot but it's not
really compulsory and you can totally
totally not focus on the programming
ball surely you cannot totally ignore it
but you can move your focus a lot more
on the tools and the skill sets that are
required to become devops engineers all
right now that the prerequisites are
complete let's go ahead and move on and
understand the journey to become a
devops engineer the step one to become a
devops engineer is to spend a lot of
time on Linux and at least I recommend
at two months a dedicated two months to
be on Linux no matter what cloud
infrastructure you are choosing to move
your production code maybe that's the
basic Linux servers or maybe that's AWS
gcp Azure one thing which is common in
all the devops engineer skill set is
Linux and the more you know about Linux
the better it is and understand the
basic commands of it how the graph works
and understand the basic networking of
it the Disk Management how it works how
the namespaces work in the Linux spoiler
alert namespaces are a great Concept in
Linux and somewhat inspired how the
containerization and Docker works so the
whole idea is the more you know your
Linux the more you're going to be
performing better as a devops engineer
and I would not hesitate to recommend
that if you are really serious becoming
a devops engineer don't hesitate to
install Linux onto your even Main
machine make sure to do take the backup
you will be crying a lot a little bit
probably a lot and it is not going to be
an easy Journey probably your videos are
not going to play probably your drivers
are not going to make sense but the
fast-paced way of learning in Linux is
simply to install it on their main
machine and cry out every day the
foundation of Linux is just Linux it
doesn't really matter too much so if you
are a fanboy of Ubuntu or maybe Centos
maybe pop OS whatever suits you just go
ahead and get friendly with the Linux
environment once you feel absolutely
comfortable with Linux then go ahead and
move on with the git now it doesn't
really matter if it is a git lab or
GitHub the git concepts are really
important you'll be dealing with them
quite a lot so having a comfortable life
with a git is going to make your life a
lot easier so spend some time on git
after that once you're done with that I
recommend you to spend some time or
probably two days with the yaml yes two
days are more than enough to learn and
understand yaml yaml is more of a like
an instructional set language it doesn't
include any program programming it's
just an instruction that eventually you
will be using as a devops engineer these
instructions are given to the computers
that hey I need an infrastructure maybe
which has this much of RAM and this much
of machines and I want to set up a
database all this you can write in the
instruction we'll talk about that later
on but yaml is one of the language which
I highly recommend that you master early
on in your devops journey alright you
have done this much great start as a
devops engineer now the life of a devops
engineer revolves around a lot of code
yes there are dedicated Cloud engineers
and the devops and yes people do
consider them as separate one but the
chances are high that you need to have
this knowledge as well now pick up your
favorite Cloud for me it's going to be
AWS but it's equally same for Azure and
gcp as well AWS offer a lot more
services and is a lot more in demand and
a lot of startups use them but the
demand for AWS and Azure are kind of
growing at the same time and the most
important part is the machines the
servers that you're spinning up are
gonna cost almost equally same on AWS
and Azure yes I know there's a
difference but the point of saying that
is you'll be spinning some servers it
doesn't really matter you are borrowing
these machines from Jeff Bezos or maybe
Sundar pichai you need to borrow them
with someone the more you are
comfortable with the cloud environment
the more you are making your life easier
now I personally prefer AWS on that
because you can actually easily complete
a few certification on AWS as well
during this journey and that will surely
add an added Advantage into your resume
as well as in your interview as well it
gives a confidence to the person who is
hiring that this guy knows his stuff he
has also proven that why some
certification in case you want to do
that otherwise having the knowledge
in-depth knowledge of the cloud and ins
and out how that works is really
essential and one thing I would like to
add here is that it's not about working
in a controlled environment the true
knowledge of cloud comes up when you
actually jump into the main Cloud yes
I'm pretty sure a lot of you might be
afraid of spinning up the servers may be
ramping up the bill that's okay AWS is
really friendly and even if you shoot up
an email that hey I was just learning
probably I accidentally shot up the
email and the bill you can actually go
ahead and reduce them down but the idea
is play in the real Waters and learn
there so don't be hesitant too much with
the AWS if you're following a proper
guide if you are having a good Mentor
who is teaching you well I'm sure that
you will be comfortable in not spinning
up the bill too much listen closely and
you won't be a hesitant there but again
here's my personal advice learn AWS in
the Real Environment will help you a lot
let's just say you have picked up AWS
and now you're quite comfortable with
spinning up machines and even horizontal
scaling vertical scaling you know about
what kind of storage is given to you
you're pretty much comfortable with AWS
what next then comes up two most
important Technologies which are used
these days quite a lot the docker and
the kubernetes docker is a way how you
containerize your application and put
that onto the servers and in order to
make sure that these servers and these
containers basically are always up and
running if some container goes bad and
goes down there is something which is
monitoring them and making sure that
these containers are available all the
time the load on one machine is not too
much you can kind of distribute your
load with different containers on
different machine that is where your
kubernetes comes into the picture yes I
agree the name kubernetes sounds
daunting but it makes you Cloud
independent you can spin up the same
servers and same configurations same
containers in AWS and gcp and you can
move on freely and that is why people
love kubernetes so much alright you have
done so much that means you are already
60 to 70 percent into the devops your
name and probably you are also ready to
apply for a lot of companies and yes it
doesn't make you a full grade Pro devops
engineer but I think you have gone a
great start so only this much of the
topic will make you a really good devops
engineer but obviously you are into the
roadmap you want to take one step
further now comes the Journey of
learning about the tools and the
terraform the tools like ansible
something like GitHub actions Argo CD or
maybe Circle CI these tools are not
going to take too much of the time
because you have spent good amount of
time in working up of your foundation
all of these uh probably each one is
going to take a week or probably 15 days
to get started not to master it but to
have enough knowledge that you can
present yourself that I know some stuff
about it after doing this much I would
personally recommend you to spend a lot
of time with infrastructure as a code
and there are a lot of tools for it
something like terraform maybe pulumi
yes there are more coming out every
single day but once you understand the
concept of how to write configuration in
a yaml file and then make it up and
running and you can spin up an entire
infrastructure for a company with just
some line of code not just basically
code instructional code yes yaml files
then you will understand the true power
of what infrastructure of infrastructure
as a code is one personal advice I would
like to give you at this point if you
have gone through with all those tools
that I have mentioned right now the tool
list never ends there could be
Prometheus there could be grafana and
there could be more monitoring tool that
will help a devops engineer to walk
through in the daily life but don't fall
into the tool hell yes just like we have
a tutorial hell we also have a tool hell
in the devops world learning unlimited
tools is not going to make you a better
devops engineer the better devops
engineer you're going to become when
you're going to actually understand that
what is the daily working of the devops
engineer and can I simulate that can I
go ahead and just make or take a dummy
application and can make it scalable
onto the cloud how can I monitor that
can I containerize that that is going to
make you a better devops engineer than
instead of just falling into the tools
hell remember the best devops engineer
is somebody who is not being noticed in
the company if you are getting noticed
every week in the company that means
something is going down devops is kind
of a role where nobody asks you where
you are even if everything is running
fine in the company so make sure you can
and that kind of devops engineer after
this comes up to the very first point
who is going to hire fresher in the
devops industry I agree that the jobs
for the freshers and devops Industry are
little bit scarce and it's not like too
much there are still enough of plethora
of jobs for junior devops engineer the
idea behind making yourself skilled and
making yourself in a friendly with the
project is to work and just again as I
say a lot of people comes from a very
containerized environment they haven't
learned or even logged in into AWS
environment these kinds of people are
considered as fresher just like in the
web development somebody comes up that
hey I have created my e-commerce
application and I have pushed this app
and my apps are there in the Android
store he's not fresher obviously he has
not worked in the company but he's not
fresher he knows what he's doing
similarly in the devops world you can
put some of the code on your GitHub and
can say that hey this is the code that I
have been using and this is the code
that I've been creating in the yaml file
to do this to do XYZ I'll definitely if
you request enough if in the comment
section I'll come up with some of the
use cases and I can give you some of the
examples that hey these are the things
that you can do in your devops journey
and can present them to your interviewer
that hey these are the work that I have
done this is known as taking experience
on your own and yes there are many ways
how you can do it if enough people
request in the comment section I'll give
you a list of four to five such of
self-experience that you can take as a
devops engineer this guide was designed
so that you don't get bogged down and
you don't get confused as a devops
engineer you get a clear precise path of
how to become a devops engineer and what
all the tool set and skill sets that you
need to learn I hope you have enjoyed
that in case you have enjoyed that check
out links in the comments section first
pin comment of course and make sure you
comment down that how do you like the
video if you like more such video which
are not just the superficial videos the
in-depth guide of how we use it every
single day how we teach stuff and how do
we write code and devop stuff make sure
you hit that subscribe button I would be
really really happy with that in case
not that's also it's fine then you can
hang it on on the channel anyways if you
have any doubt at all go ahead and reach
me out on my Instagram I'm super active
there or put a question on my LinkedIn
inbox I would be happy to answer any of
the question that you have that's it for
