1
00:00:00,000 --> 00:00:02,759
Exposure to other technologies. Okay, so

2
00:00:02,759 --> 00:00:04,649
now you already know Linux, you know a

3
00:00:04,649 --> 00:00:07,229
lot about actually Linux. So why do you

4
00:00:07,229 --> 00:00:09,449
need to know about other technologies as

5
00:00:09,449 --> 00:00:11,699
well? Well, if you are going for System

6
00:00:11,699 --> 00:00:13,709
Administration, trust me, they will ask

7
00:00:13,709 --> 00:00:15,029
you some questions about other

8
00:00:15,029 --> 00:00:17,369
technologies as well. And they expect a

9
00:00:17,369 --> 00:00:20,369
person who is fulfilling for a system

10
00:00:20,429 --> 00:00:23,429
administrator or engineer job to know a

11
00:00:23,429 --> 00:00:25,739
few things about some other technology

12
00:00:25,739 --> 00:00:28,769
as well. So this lesson is about that. I

13
00:00:28,769 --> 00:00:30,959
will recommend you to go online, look

14
00:00:30,959 --> 00:00:32,848
for those other things, specifically for

15
00:00:32,848 --> 00:00:34,949
system administrator. The first one is

16
00:00:34,949 --> 00:00:37,229
about operating system. You know Linux,

17
00:00:37,259 --> 00:00:39,989
that's number one, your expertise are on

18
00:00:39,989 --> 00:00:43,139
Linux. The second one is about Windows.

19
00:00:43,169 --> 00:00:44,609
You do need to know windows, if you are

20
00:00:44,609 --> 00:00:46,379
already a Windows user, you have a

21
00:00:46,379 --> 00:00:49,019
laptop or PC running Windows, perfect.

22
00:00:49,019 --> 00:00:50,489
Look for a few other things, how to

23
00:00:50,489 --> 00:00:54,389
change IPs, how to send traffic from one

24
00:00:54,419 --> 00:00:56,429
Windows machine to another, a few

25
00:00:56,429 --> 00:00:58,829
Windows administration on YouTube, if

26
00:00:58,829 --> 00:01:02,309
you want to, virtualization technology,

27
00:01:02,339 --> 00:01:04,888
the biggest one is VMware. There are a

28
00:01:04,888 --> 00:01:07,499
lot of articles on VMware, what virtual

29
00:01:07,499 --> 00:01:09,569
technology is, how it works, and I will

30
00:01:09,569 --> 00:01:11,759
recommend you to go online and check out

31
00:01:11,759 --> 00:01:14,099
for it. Then we have a hardware. In the

32
00:01:14,099 --> 00:01:16,709
hardware side, you should know what

33
00:01:16,709 --> 00:01:20,309
hardware are used to install your

34
00:01:20,309 --> 00:01:22,679
operating system on. The biggest market

35
00:01:22,679 --> 00:01:25,409
of hardware is Dell and HP. So go

36
00:01:25,409 --> 00:01:27,689
online, go to the Dell website or HP

37
00:01:27,689 --> 00:01:29,669
website and find out what are the latest

38
00:01:29,669 --> 00:01:31,469
models that they have? What other

39
00:01:31,469 --> 00:01:34,169
specs will help? What are the rack units

40
00:01:34,439 --> 00:01:37,199
or how to access them? Read a few, a

41
00:01:37,199 --> 00:01:39,239
little about hardware. So this way, if

42
00:01:39,239 --> 00:01:41,099
you are at the interview, you could tell

43
00:01:41,099 --> 00:01:44,879
them that you know about Dell server,

44
00:01:44,879 --> 00:01:48,539
let's say R720, R620, you have worked

45
00:01:48,539 --> 00:01:50,909
on it, or have you have knowledge about

46
00:01:50,909 --> 00:01:53,879
it. Then monitoring tools. When you have

47
00:01:53,879 --> 00:01:55,619
environment that you are supporting, you

48
00:01:55,649 --> 00:01:58,139
do need to monitor them as well.

49
00:01:58,139 --> 00:01:59,849
Right. Some of the monitoring tools are

50
00:01:59,849 --> 00:02:02,849
like Nagios, Splunk, and Zenoss. These

51
00:02:02,849 --> 00:02:04,589
are the type of technologies I will

52
00:02:04,589 --> 00:02:06,809
recommend you to go online search for

53
00:02:06,809 --> 00:02:11,249
them, look for them in YouTube. Cloud is

54
00:02:11,249 --> 00:02:13,079
another platform where a lot of

55
00:02:13,258 --> 00:02:14,909
virtualization technology has been

56
00:02:14,939 --> 00:02:17,399
moving to from VMware, from Redhat

57
00:02:17,399 --> 00:02:20,159
virtualization to Amazon Cloud. What is

58
00:02:20,159 --> 00:02:22,739
an Amazon? Well, this is for you to find

59
00:02:22,739 --> 00:02:26,039
out. Amazon has many different products

60
00:02:26,069 --> 00:02:28,289
that they offer. The product that you

61
00:02:28,289 --> 00:02:31,679
should look into, on the Amazon cloud is

62
00:02:31,679 --> 00:02:35,399
called Amazon EC2. It stands for Amazon

63
00:02:35,429 --> 00:02:39,269
Elastic Cloud 2, which allows you to

64
00:02:39,269 --> 00:02:43,319
create your virtual machines or build up

65
00:02:43,319 --> 00:02:45,149
your applications on the virtual

66
00:02:45,149 --> 00:02:47,729
machines based on your requirement. So

67
00:02:47,729 --> 00:02:50,609
if you need an application to run from

68
00:02:50,609 --> 00:02:53,009
only nine to five, and then the machine

69
00:02:53,039 --> 00:02:54,509
you don't want the resource in the

70
00:02:54,509 --> 00:02:56,519
machine, you could schedule that, then

71
00:02:56,519 --> 00:02:58,679
after nine to five it will shut it down. So

72
00:02:58,679 --> 00:03:01,739
this EC2 is a very, very efficient

73
00:03:01,739 --> 00:03:04,949
and valuable product. Look into it and

74
00:03:05,009 --> 00:03:08,459
read about it. This is where the

75
00:03:08,489 --> 00:03:12,299
technology is going to. We will be on on

76
00:03:12,299 --> 00:03:15,359
Cloud sooner or later. Then we have

77
00:03:15,389 --> 00:03:17,699
operating system tools like Redhat

78
00:03:17,699 --> 00:03:20,519
Satellite, which allows you to download

79
00:03:20,519 --> 00:03:22,979
and update packages, if you do not have

80
00:03:22,979 --> 00:03:26,249
access to the Redhat portal. Kickstart,

81
00:03:26,309 --> 00:03:28,469
kickstart, is an integrated product

82
00:03:28,559 --> 00:03:30,149
within the Redhat Satellite, which

83
00:03:30,179 --> 00:03:32,669
allows you to automate your installation

84
00:03:32,669 --> 00:03:36,659
of Linux Redhat. Active Directory tool

85
00:03:36,659 --> 00:03:38,549
is also one of the important tools that

86
00:03:38,549 --> 00:03:40,529
you should know, which is a product of

87
00:03:40,529 --> 00:03:45,749
Microsoft. It lets you manage your users

88
00:03:45,749 --> 00:03:48,749
in groups. It integrates with Linux as

89
00:03:48,749 --> 00:03:52,649
well. DNS, which is being built by many

90
00:03:52,649 --> 00:03:54,479
different vendors as well, and the

91
00:03:54,479 --> 00:03:56,009
Pioneer one I would say again as

92
00:03:56,009 --> 00:03:59,729
Microsoft, they are done an amazing job

93
00:03:59,729 --> 00:04:02,759
in DNS as well. Look for DNS build and

94
00:04:02,759 --> 00:04:04,799
configuration on the Microsoft platform.

95
00:04:05,219 --> 00:04:07,529
Then we have Puppet, Chef, or Ansible.

96
00:04:07,529 --> 00:04:09,749
These are also the automation tools to

97
00:04:09,779 --> 00:04:12,359
automate your installation. And

98
00:04:12,359 --> 00:04:15,179
nowadays, a lot of vendors or a lot of

99
00:04:15,179 --> 00:04:17,339
companies actually are asking for these

100
00:04:17,339 --> 00:04:19,349
tools if you know them. I would say

101
00:04:19,349 --> 00:04:20,759
spend some time on one of those

102
00:04:20,759 --> 00:04:22,469
technology either Puppet, Chef or

103
00:04:22,469 --> 00:04:24,149
Ansible, which will automate the

104
00:04:24,149 --> 00:04:28,319
installation. Then the last one is the

105
00:04:28,319 --> 00:04:31,709
database. Database is anything that

106
00:04:32,039 --> 00:04:34,949
manages your data. If you have a big

107
00:04:34,949 --> 00:04:36,179
environment, you definitely need a

108
00:04:36,179 --> 00:04:37,919
database, you need to know what a

109
00:04:37,919 --> 00:04:40,709
database is, how it interacts with the

110
00:04:40,709 --> 00:04:43,799
application or the operating system, how

111
00:04:43,799 --> 00:04:47,039
the SQL, Microsoft SQL database works,

112
00:04:47,039 --> 00:04:49,529
how it gets installed, or what are the

113
00:04:49,559 --> 00:04:51,719
databases that gets installed on Linux

114
00:04:51,719 --> 00:04:54,299
platform. So anyway, these are the few

115
00:04:54,299 --> 00:04:56,939
technologies please please please focus on them.

116
00:04:57,239 --> 00:04:59,639
Spend some time on them, along with

117
00:04:59,639 --> 00:05:01,289
Linux, of course you have spent so much

118
00:05:01,289 --> 00:05:03,359
time on Linux right, spend some time

119
00:05:03,359 --> 00:05:04,619
little bit more time on these

120
00:05:04,619 --> 00:05:06,389
technologies, this will definitely help

121
00:05:06,389 --> 00:05:08,249
you go through your interview process.
