Exposure to other technologies. Okay, so
now you already know Linux, you know a
lot about actually Linux. So why do you
need to know about other technologies as
well? Well, if you are going for System
Administration, trust me, they will ask
you some questions about other
technologies as well. And they expect a
person who is fulfilling for a system
administrator or engineer job to know a
few things about some other technology
as well. So this lesson is about that. I
will recommend you to go online, look
for those other things, specifically for
system administrator. The first one is
about operating system. You know Linux,
that's number one, your expertise are on
Linux. The second one is about Windows.
You do need to know windows, if you are
already a Windows user, you have a
laptop or PC running Windows, perfect.
Look for a few other things, how to
change IPs, how to send traffic from one
Windows machine to another, a few
Windows administration on YouTube, if
you want to, virtualization technology,
the biggest one is VMware. There are a
lot of articles on VMware, what virtual
technology is, how it works, and I will
recommend you to go online and check out
for it. Then we have a hardware. In the
hardware side, you should know what
hardware are used to install your
operating system on. The biggest market
of hardware is Dell and HP. So go
online, go to the Dell website or HP
website and find out what are the latest
models that they have? What other
specs will help? What are the rack units
or how to access them? Read a few, a
little about hardware. So this way, if
you are at the interview, you could tell
them that you know about Dell server,
let's say R720, R620, you have worked
on it, or have you have knowledge about
it. Then monitoring tools. When you have
environment that you are supporting, you
do need to monitor them as well.
Right. Some of the monitoring tools are
like Nagios, Splunk, and Zenoss. These
are the type of technologies I will
recommend you to go online search for
them, look for them in YouTube. Cloud is
another platform where a lot of
virtualization technology has been
moving to from VMware, from Redhat
virtualization to Amazon Cloud. What is
an Amazon? Well, this is for you to find
out. Amazon has many different products
that they offer. The product that you
should look into, on the Amazon cloud is
called Amazon EC2. It stands for Amazon
Elastic Cloud 2, which allows you to
create your virtual machines or build up
your applications on the virtual
machines based on your requirement. So
if you need an application to run from
only nine to five, and then the machine
you don't want the resource in the
machine, you could schedule that, then
after nine to five it will shut it down. So
this EC2 is a very, very efficient
and valuable product. Look into it and
read about it. This is where the
technology is going to. We will be on on
Cloud sooner or later. Then we have
operating system tools like Redhat
Satellite, which allows you to download
and update packages, if you do not have
access to the Redhat portal. Kickstart,
kickstart, is an integrated product
within the Redhat Satellite, which
allows you to automate your installation
of Linux Redhat. Active Directory tool
is also one of the important tools that
you should know, which is a product of
Microsoft. It lets you manage your users
in groups. It integrates with Linux as
well. DNS, which is being built by many
different vendors as well, and the
Pioneer one I would say again as
Microsoft, they are done an amazing job
in DNS as well. Look for DNS build and
configuration on the Microsoft platform.
Then we have Puppet, Chef, or Ansible.
These are also the automation tools to
automate your installation. And
nowadays, a lot of vendors or a lot of
companies actually are asking for these
tools if you know them. I would say
spend some time on one of those
technology either Puppet, Chef or
Ansible, which will automate the
installation. Then the last one is the
database. Database is anything that
manages your data. If you have a big
environment, you definitely need a
database, you need to know what a
database is, how it interacts with the
application or the operating system, how
the SQL, Microsoft SQL database works,
how it gets installed, or what are the
databases that gets installed on Linux
platform. So anyway, these are the few
technologies please please please focus on them.
Spend some time on them, along with
Linux, of course you have spent so much
time on Linux right, spend some time
little bit more time on these
technologies, this will definitely help
you go through your interview process.
