[No audio]

2
00:00:01,890 --> 00:00:04,019
After looking at examples of operating

3
00:00:04,019 --> 00:00:07,800
systems, now let's go over the actual

4
00:00:07,860 --> 00:00:11,940
operating system jobs. If you like

5
00:00:11,970 --> 00:00:14,610
operating system and you want to deal

6
00:00:14,700 --> 00:00:17,610
with operating system layer, where you

7
00:00:17,610 --> 00:00:19,500
don't want to touch the hardware, you

8
00:00:19,500 --> 00:00:21,720
don't want to have a screwdriver in your

9
00:00:21,720 --> 00:00:24,030
hand, and you just want to deal with

10
00:00:24,240 --> 00:00:26,220
typing and working with the operating

11
00:00:26,220 --> 00:00:28,500
system level, then the these are the

12
00:00:28,500 --> 00:00:31,500
list of jobs you should look into. The

13
00:00:31,500 --> 00:00:33,870
first one that I have is the System

14
00:00:33,870 --> 00:00:37,050
Administrators jobs. Now, this is the

15
00:00:37,050 --> 00:00:40,020
primary and basic job of System

16
00:00:40,020 --> 00:00:42,420
Administrator, is to actually deal with

17
00:00:42,420 --> 00:00:45,930
the operating system. Any issue that you

18
00:00:45,930 --> 00:00:48,960
have with the operating system, any type

19
00:00:48,960 --> 00:00:52,590
of implementation. You are responsible

20
00:00:52,590 --> 00:00:55,500
for installing the operating system, you

21
00:00:55,500 --> 00:00:57,450
are responsible for configuring the

22
00:00:57,450 --> 00:00:59,130
hardware at the first time when it

23
00:00:59,160 --> 00:01:01,830
arrives at your data center, you are

24
00:01:01,830 --> 00:01:05,160
responsible to upgrade its firmware, if

25
00:01:05,160 --> 00:01:06,810
there is a need, you are responsible to

26
00:01:06,810 --> 00:01:09,330
configure it through its console. You

27
00:01:09,330 --> 00:01:12,270
install the operating system, and you

28
00:01:12,270 --> 00:01:14,820
configure the operating system. So these

29
00:01:14,820 --> 00:01:16,080
are the type of jobs System

30
00:01:16,080 --> 00:01:18,900
Administrators do. Also you deal

31
00:01:18,930 --> 00:01:21,360
extensively with operating system

32
00:01:21,360 --> 00:01:24,330
troubleshooting. If you have an issue,

33
00:01:24,330 --> 00:01:27,300
and you most likely, those issues are

34
00:01:27,300 --> 00:01:30,210
going to get escalated from the PC

35
00:01:30,210 --> 00:01:32,880
technicians or IT help desk they cannot

36
00:01:32,880 --> 00:01:35,460
resolve it. So it will be escalated to

37
00:01:35,460 --> 00:01:39,240
you. Then we have Systems Engineers.

38
00:01:39,390 --> 00:01:42,090
Systems Engineers are those people who

39
00:01:42,120 --> 00:01:44,070
are actually been through the System

40
00:01:44,070 --> 00:01:46,620
Administration jobs in their life. And

41
00:01:46,620 --> 00:01:48,720
now they are at the Engineering level,

42
00:01:48,720 --> 00:01:52,740
which is a one step up. In this

43
00:01:52,740 --> 00:01:56,550
Engineering level, you actually design

44
00:01:56,730 --> 00:01:59,460
the entire infrastructure, you actually

45
00:01:59,460 --> 00:02:01,440
build the infrastructure together, not

46
00:02:01,440 --> 00:02:03,690
just one server, but many, many

47
00:02:03,690 --> 00:02:06,630
different servers. Then you have Web

48
00:02:06,630 --> 00:02:08,490
Application Administrators. They are

49
00:02:08,490 --> 00:02:10,860
also the ones who deals with building

50
00:02:11,070 --> 00:02:13,979
the web sites, particularly any, any

51
00:02:14,009 --> 00:02:15,660
websites, they're running on operating

52
00:02:15,660 --> 00:02:18,300
systems, it's there's primary

53
00:02:18,300 --> 00:02:20,220
responsibilities, make sure that website

54
00:02:20,220 --> 00:02:22,170
is up and running. And of course, there

55
00:02:22,170 --> 00:02:25,530
are many different web servers that you

56
00:02:25,530 --> 00:02:27,960
could utilize. One of them is Apache,

57
00:02:27,960 --> 00:02:30,990
the other one is a Tomcat. Then you have

58
00:02:30,990 --> 00:02:33,780
Infrastructure Engineers. Infrastructure

59
00:02:33,780 --> 00:02:35,910
Engineers are all in all, they are the

60
00:02:35,910 --> 00:02:37,740
one who actually deal with many

61
00:02:37,740 --> 00:02:40,800
different components of it, not just

62
00:02:40,800 --> 00:02:42,630
this operating system, but they also

63
00:02:42,630 --> 00:02:44,940
deal with somewhat of hardware. They

64
00:02:44,940 --> 00:02:47,190
deal with the operating system, they

65
00:02:47,190 --> 00:02:49,410
deal with somewhat of applications,

66
00:02:49,590 --> 00:02:52,770
somewhat database, and many, that they

67
00:02:52,770 --> 00:02:54,090
actually touch many different

68
00:02:54,090 --> 00:02:57,210
technologies. Then you have Solution

69
00:02:57,240 --> 00:02:59,970
Engineers. Solution Engineers, and the

70
00:03:00,000 --> 00:03:02,400
Architects are the one who actually

71
00:03:02,670 --> 00:03:06,060
designed put on a blue blueprint and put

72
00:03:06,060 --> 00:03:08,040
it together, how many servers do we need

73
00:03:08,040 --> 00:03:10,470
to build this entire data centers, how

74
00:03:10,470 --> 00:03:12,480
many servers, or how many storage, how

75
00:03:12,480 --> 00:03:14,850
many networking devices, we need to

76
00:03:14,850 --> 00:03:16,860
complete this entire data center, those

77
00:03:16,860 --> 00:03:19,650
are the people who actually deals with

78
00:03:19,680 --> 00:03:22,020
blueprint off your infrastructure.

79
00:03:22,020 --> 00:03:25,920
[No audio]

80
00:03:25,920 --> 00:03:28,620
DevOps Engineers, now DevOps Engineers

81
00:03:28,620 --> 00:03:30,960
are actually the title or the role that

82
00:03:30,960 --> 00:03:34,590
has been recently created. I should, I

83
00:03:34,590 --> 00:03:36,420
should say, not more than two to

84
00:03:36,420 --> 00:03:39,390
five years ago. This is actually the

85
00:03:39,390 --> 00:03:42,660
combination of people who work with

86
00:03:42,660 --> 00:03:45,120
operating system, as well as who

87
00:03:45,120 --> 00:03:48,810
actually very fluent in programming

88
00:03:48,810 --> 00:03:51,840
languages. So not only they actually

89
00:03:51,840 --> 00:03:53,850
manage the infrastructure, manage the

90
00:03:53,850 --> 00:03:56,100
system, they also want someone who

91
00:03:56,100 --> 00:03:59,130
could write the codes, who could actually

92
00:03:59,130 --> 00:04:01,890
know some languages in many languages or

93
00:04:01,890 --> 00:04:06,060
like perhaps Java, C, C++, and many

94
00:04:06,060 --> 00:04:08,610
other languages, which I will cover in

95
00:04:08,610 --> 00:04:10,560
the later lecture. So these are the

96
00:04:10,560 --> 00:04:12,360
people who are actually DevOps

97
00:04:12,360 --> 00:04:14,580
Engineers, they definitely make a lot of

98
00:04:14,580 --> 00:04:16,769
money. And if this is something that you

99
00:04:16,769 --> 00:04:19,410
want to get in, you always have to start

100
00:04:19,410 --> 00:04:22,200
your path from help desk to operating

101
00:04:22,200 --> 00:04:24,300
System Engineer, Infrastructure Engineer

102
00:04:24,300 --> 00:04:25,920
get into more knowledge of the

103
00:04:25,920 --> 00:04:28,410
programming languages, and to the DevOps

104
00:04:28,410 --> 00:04:30,990
Engineer. Then we have field Engineers,

105
00:04:31,020 --> 00:04:32,790
these are the people who actually work

106
00:04:32,790 --> 00:04:36,450
for the companies like Redhat, HP, and

107
00:04:36,450 --> 00:04:38,610
all those big companies. And what they

108
00:04:38,610 --> 00:04:41,280
do is they actually go out on a field

109
00:04:41,280 --> 00:04:44,190
trip to a customer site or client site

110
00:04:44,400 --> 00:04:48,660
to fix their computers. They are

111
00:04:48,660 --> 00:04:51,120
also fixing the operating system as well

112
00:04:51,120 --> 00:04:53,790
as the hardware. These field Engineers

113
00:04:54,180 --> 00:04:56,550
are the one let's say if they are from

114
00:04:56,550 --> 00:04:57,900
Redhat they is going to they're going

115
00:04:57,900 --> 00:05:00,360
to come on site and if there are issue, they can

116
00:05:00,360 --> 00:05:02,700
spend some, they're going to spend some

117
00:05:02,700 --> 00:05:04,560
time to troubleshoot the issues with

118
00:05:04,560 --> 00:05:09,150
you. So if you are into traveling, if

119
00:05:09,150 --> 00:05:12,360
you are into working outside, you are

120
00:05:12,360 --> 00:05:15,060
not the person who wants to sit on your

121
00:05:15,060 --> 00:05:18,120
desk, then this is the right job for

122
00:05:18,120 --> 00:05:21,180
you. But again, for this type of job,

123
00:05:21,180 --> 00:05:23,310
you do need to know the operating

124
00:05:23,310 --> 00:05:25,830
system, and which operating system that

125
00:05:25,830 --> 00:05:28,170
I have already covered that in my

126
00:05:28,170 --> 00:05:30,570
previous slide, those are the list of

127
00:05:30,600 --> 00:05:32,370
operating system that you guys should

128
00:05:32,400 --> 00:05:35,730
pick and go over it. Then product

129
00:05:35,730 --> 00:05:37,890
Engineers, product Engineers, of course,

130
00:05:37,920 --> 00:05:40,110
are very much similar to field

131
00:05:40,110 --> 00:05:42,630
Engineers. However, product Engineers

132
00:05:42,720 --> 00:05:45,990
only deal specifically to one product.

133
00:05:46,230 --> 00:05:50,580
So if let's say Redhat has a product, a

134
00:05:50,580 --> 00:05:54,060
new product called virtualization, their

135
00:05:54,060 --> 00:05:56,220
new virtualization technology, or their

136
00:05:56,220 --> 00:05:59,430
satellite technology, or any product,

137
00:05:59,460 --> 00:06:01,800
they actually have people who actually

138
00:06:01,800 --> 00:06:04,770
deal specifcally in that technology. So

139
00:06:04,800 --> 00:06:08,040
when they sell those technologies out to

140
00:06:08,040 --> 00:06:09,690
the people, to the consumers to the

141
00:06:09,690 --> 00:06:12,000
clients, then these product Engineers

142
00:06:12,000 --> 00:06:14,640
are the one who actually traveled with

143
00:06:14,640 --> 00:06:17,700
the sales guys to actually help them

144
00:06:17,700 --> 00:06:21,060
sell that product and tell them about the technology.

145
00:06:22,320 --> 00:06:24,510
Then you have the principal Engineer,

146
00:06:24,510 --> 00:06:26,820
pretty much principal Engineers job is

147
00:06:26,820 --> 00:06:30,690
the same as Systems Engineer with a lot

148
00:06:30,690 --> 00:06:33,420
more responsibility. Sometimes principal

149
00:06:33,420 --> 00:06:35,460
Engineers are also the ones who have

150
00:06:35,460 --> 00:06:37,650
some type of lead. They also manage some

151
00:06:37,650 --> 00:06:40,020
System Administrators. Then you have

152
00:06:40,020 --> 00:06:43,080
platform Engineers, platform Engineers

153
00:06:43,080 --> 00:06:46,110
are specific to one platform, they, if

154
00:06:46,110 --> 00:06:48,840
if a company has multiple operating

155
00:06:48,840 --> 00:06:51,030
system environment, most likely they're

156
00:06:51,030 --> 00:06:53,760
going to deal with one platform, or some

157
00:06:53,760 --> 00:06:57,330
one of the most two operating systems.

158
00:06:57,660 --> 00:07:00,060
Then we have backend and datacenter

159
00:07:00,060 --> 00:07:02,340
Engineers who are actually sitting at

160
00:07:02,340 --> 00:07:05,820
the data center or who often travel to

161
00:07:05,820 --> 00:07:07,710
the data center, every time there is an

162
00:07:07,710 --> 00:07:10,110
issue. Of course, if there's an issue,

163
00:07:10,110 --> 00:07:14,100
they in you, you will call your, your

164
00:07:14,100 --> 00:07:16,230
vendor, they will charge a lot of money

165
00:07:16,230 --> 00:07:17,820
or you might have to have a contract

166
00:07:17,820 --> 00:07:20,917
with them. But with the backend datacenter Engineer,

167
00:07:20,917 --> 00:07:21,960
they are most likely

168
00:07:21,960 --> 00:07:23,580
close to the data center, will travel

169
00:07:23,580 --> 00:07:25,890
there all the time, who are

170
00:07:25,890 --> 00:07:27,780
responsible for racking and stacking the

171
00:07:27,780 --> 00:07:29,280
servers, building the servers,

172
00:07:29,280 --> 00:07:32,610
troubleshooting the systems. Then I have

173
00:07:32,610 --> 00:07:35,640
the implementation consultants. I will

174
00:07:35,640 --> 00:07:38,250
focus on the consultant part here

175
00:07:38,250 --> 00:07:40,890
because many of the jobs that most

176
00:07:40,890 --> 00:07:42,750
likely that you will be getting into

177
00:07:42,750 --> 00:07:45,540
will be the consulting jobs. What it

178
00:07:45,540 --> 00:07:48,720
means, that you might not get into the

179
00:07:48,720 --> 00:07:51,420
full time job right right out the door,

180
00:07:51,420 --> 00:07:53,820
you will have to spend some time

181
00:07:53,820 --> 00:07:56,850
consulting. And I tell you and I kid you

182
00:07:56,850 --> 00:08:00,360
not, if you get into the consulting job,

183
00:08:00,360 --> 00:08:03,150
you will learn a lot. Because in

184
00:08:03,150 --> 00:08:06,000
consulting jobs, you have to actually

185
00:08:06,180 --> 00:08:09,780
fulfill a task at a specific time, at a

186
00:08:09,780 --> 00:08:12,210
specific rate. So when you have that kind

187
00:08:12,210 --> 00:08:14,370
of pressure, you will learn a lot. And

188
00:08:14,400 --> 00:08:18,210
also if you are not a person who want to

189
00:08:18,210 --> 00:08:20,310
work for a boss, you want to work for

190
00:08:20,310 --> 00:08:22,380
yourself, that consulting job is for

191
00:08:22,380 --> 00:08:24,570
you. There are advantages and

192
00:08:24,570 --> 00:08:27,150
disadvantages of consulting. One is you

193
00:08:27,150 --> 00:08:29,250
don't get the benefits for example,

194
00:08:29,250 --> 00:08:31,500
medicals and health insurance. Whereas

195
00:08:31,500 --> 00:08:34,119
on the regular full time job on the W2

196
00:08:34,119 --> 00:08:35,820
jobs, you get all those benefits,

197
00:08:36,000 --> 00:08:37,830
but at the same time you have a boss, you

198
00:08:37,830 --> 00:08:41,549
have to report him. So anyway, guys,

199
00:08:41,549 --> 00:08:45,090
this is the list of job titles that I

200
00:08:45,090 --> 00:08:48,630
have covered under operating systems.

201
00:08:48,659 --> 00:08:51,419
Again, operating system is the layer, is

202
00:08:51,419 --> 00:08:53,700
an operating system is a software that

203
00:08:53,700 --> 00:08:57,450
runs on top of the computer. If you like

204
00:08:57,480 --> 00:09:00,510
that piece, that layer, and that's where

205
00:09:00,510 --> 00:09:03,660
you want to get your hands on, this is

206
00:09:03,660 --> 00:09:05,430
where you should spend your time and,

207
00:09:05,760 --> 00:09:07,470
and how you're going to get to spend

208
00:09:07,470 --> 00:09:10,230
time and let's say even if you are on

209
00:09:10,230 --> 00:09:13,860
Udemy or any other websites that are

210
00:09:13,860 --> 00:09:16,680
educational, and they are teaching you

211
00:09:16,680 --> 00:09:20,040
courses, all you have to do is go in and

212
00:09:20,040 --> 00:09:21,660
put it in let's say Redhat

213
00:09:21,660 --> 00:09:23,550
Administration or Windows operating

214
00:09:23,550 --> 00:09:27,360
System Administration or Mac OS

215
00:09:27,750 --> 00:09:30,450
Administration, or Mac operating system,

216
00:09:30,450 --> 00:09:32,610
you're going to find tons and tons of

217
00:09:32,610 --> 00:09:35,040
courses out there that will help you

218
00:09:35,070 --> 00:09:38,610
understand those operating system and as

219
00:09:38,610 --> 00:09:40,380
you learn those operating system, as you

220
00:09:40,380 --> 00:09:42,540
spend more time in it, I will encourage

221
00:09:42,540 --> 00:09:46,350
you to go do jobs for people, even

222
00:09:46,380 --> 00:09:48,810
internships or learn a lot about it

223
00:09:48,810 --> 00:09:50,460
from other people who already in that

224
00:09:50,460 --> 00:09:53,287
field, who could help you get into that field.

225
00:09:53,287 --> 00:09:54,901
