Job titles and duties.
My students ask me this question after taking this
course, what kind of job am I going to
be getting or what are my duties is going
to be, what I'm going to be working at?
Now those are legit questions.
So here's the time that you should know what
are the jobs that you should be applying for
or looking for and what you should be expecting
to do when you get that job.
So the basic job that you're going to
be getting is the IT technician, which is
more of a help desk technician job.
I'm not telling you to pursue specifically for this job,
but perhaps for those people who actually have never done
any kind of work in IT or don't even have
educational background in IT, and coming from completely different background,
I would say and I would recommend that they should
start with IT help desk field.
That's one of the field that is very informative.
You will get a lot of information about IT.
If you already have some of the experience in IT,
then I would say go for system administrator job.
A system administrator is an
administrator who manages the system.
And system is comprised of what?
It's comprised of hardware, software, operating systems,
networking devices, cables and all those stuff.
All that combined together make up a system.
Then the next one, another higher
level job is a system engineer.
At this level you will
be designing your entire infrastructure.
Meaning you will be putting all the computers
together, how many computers you need, how many
CPU you need, and so on and so forth.
Then of course it becomes a senior
job, senior system administrator, senior system engineers,
manager, supervisor, and so on.
So these are the titles that you look for.
Now let's talk about the duties, what
exactly you're going to be doing.
I have this Word document.
I'm going to cover all the duties one
by one and of course really quick.
Okay, so here's the document and this document
is also part of your handout.
You could download it, you could
review it after this lesson.
So the primary administration responsibility is that
you will be dealing with installing operating
system, managing the hardware, firmware, service installation
and configuration, upgrade Linux servers,
we covered that, migrate operating system
from older hardware to newer hardware.
You could do that by moving, by installing
a newer version of operating systems and newer
hardware and moving all the application, patch management,
we learned that from the yum command, third
party software installation configuration that you're going to
be dealing with many different applications that are
going to run on your computer.
Remember, we have a hardware,
then we have operating system.
Without the application, both of them are useless.
So you do need applications to run on top of them.
And once you run it, who manages that?
You are going to be managing them.
You're not going to be like really dealing
with configuration off it or using them.
The users are different as compared to you guys
who are going to be installing it.
Then different type of issues or troubleshooting that you're
going to be dealing with almost every day.
Like service is running slow, disk is down, NTP is not
working, mount issues, cannot restart the service, can't get to
the DNS, review all of them one by one.
And I assure you, we covered almost 95%
of all these issues in our training class.
So cannot log in as root using SSH
protocol, incorrect hostname, memory is high or full.
What do you need to do?
Backup is not working, of course,
most of the time backup is a third party software.
You're going to be learning that once you're going
to be joining, setup cronjob or scheduled
job, you're going to be setting those up.
Then we have documentation.
Now every job in IT specially I would
say, requires you to do the documentation.
What that documentation is, that if an issue
comes in, you document it, how you resolve it.
And if there's a new system to
do the installation, you follow the documentation
or you create your own documentation.
Then you're going to be sitting down in the meeting.
Your manager wants you to sit down, give them
the progress report, what you did the whole week.
Or you're probably going to be meeting with
vendors who are going to be coming in
with new technologies to introduce new technologies.
So meeting is going to be happening almost
at least two or three times a week,
so expect that. Additional tools that you're
going to be working with, like monitoring
tools, there's going to be a monitoring
tool that monitors your entire infrastructure, right?
So who manages that tool?
You manage that tool,
documentation tool, ticketing system.
Every issue that comes in most likely is
going to be generated inside of a ticket.
You get a ticket, you look at the ticket
and then you resolve the issue, put in your
resolution inside the ticket and close it.
And that's also one of the ways the management
actually kind of measures your performance, how many tickets
you close, how fast you close the ticket.
So this is a way for them
to kind of quantify your performance.
Then you have configuration tool, other tools like
Redhat Satellite, Puppet, kickstart, Active Directory, all
different types of tools you're going to be
working with. Vendor relations, Redhat.
If you're going to be working with Linux, most likely
you're going to be dealing a lot with Redhat.
So I would highly recommend you that
you go over to every website listed
here, register yourself there, sign up there.
You will be getting started getting the
new release, new updates and everything.
Just stay ahead of all the technologies that they have.
Redhat, HP, Dell, Cisco, VMWare, third party
vendors, Microsoft, all these companies you're going to
be dealing with almost every day.
Because once the issue is not being resolved.
Most likely you're going to be escalating to vendors.
Then third party application support you are going to be providing.
You're going to be dealing with licensing every
product that you buy or every product that
you have in your environment that you have
installed, you have to pay for it.
And it comes through the license, of course
there is someone who has to manage it.
Well sometimes managers manage those licenses.
Sometimes they give their responsibility to
system administrators who manage that.
So keep that in mind.
Other job related tasks are like
you're going to be on call.
What that means is, if a team has six people,
you're going to be getting on call every 6th week.
They're going to be giving you a phone, a laptop.
When you are home or when you are home
after hours or on the weekend an issue comes
in, you have to be present, not at the
office location but present to respond to that issue.
So that is being on call.
Be prepared for that. Recommendation,
you're going to be recommending for new technology.
How are you going to be recommending?
Well you have to attend seminars.
You have to attend and keep up
to date with all the technology.
As I said, sign up with all those vendors.
Attend training.
You're going to be going with a lot of training.
The companies are going to be providing you
trainings. Project management, evaluate third party tools, which
is more of a POC related tasks.
So these are some of the jobs
duties that you're going to be working.
There are more, there are
less depending on the environment.
Sometimes it's a smaller environment,
sometimes it's a bigger.
If it's a smaller, you might have to
wear many different hats, meaning you're going to
be doing a lot of stuff.
But it's good for you
because you're starting your career.
But if you've been there you probably want to
work for a bigger company that has a quite laid
out infrastructure in their team and probably your duty
is going to be separated from each other.
So that's what about it.
So I hope you got the gist of it and good luck.
