00:00:00,05 --> 00:00:02,09
- [Instructor] There are trade-offs you're making

2
00:00:02,09 --> 00:00:05,00
by using open source software

3
00:00:05,00 --> 00:00:08,06
over its commercial counterparts.

4
00:00:08,06 --> 00:00:12,05
Let's talk about the advantages first.

5
00:00:12,05 --> 00:00:17,07
Of course, the most obvious one is the fact that it's free,

6
00:00:17,07 --> 00:00:19,02
but is it really free?

7
00:00:19,02 --> 00:00:21,04
Isn't there any hidden costs?

8
00:00:21,04 --> 00:00:24,03
We'll investigate this question more in depth

9
00:00:24,03 --> 00:00:26,08
in the next lesson.

10
00:00:26,08 --> 00:00:30,04
Another strength is its transparency,

11
00:00:30,04 --> 00:00:33,05
which contributes to security.

12
00:00:33,05 --> 00:00:35,09
Users have access to the source code

13
00:00:35,09 --> 00:00:39,04
and know exactly what they are getting into.

14
00:00:39,04 --> 00:00:42,09
Usually, there's a vibrant community of developers

15
00:00:42,09 --> 00:00:46,05
supporting an open source of their product

16
00:00:46,05 --> 00:00:50,05
who also keep an eye on security defects.

17
00:00:50,05 --> 00:00:53,09
If there is a known bug, they know about it.

18
00:00:53,09 --> 00:00:56,06
As a result, security vulnerabilities

19
00:00:56,06 --> 00:00:59,05
don't linger too long.

20
00:00:59,05 --> 00:01:02,05
Commercial software is like a black box.

21
00:01:02,05 --> 00:01:05,00
Nobody knows what's in it

22
00:01:05,00 --> 00:01:08,01
which introduces many uncertainties

23
00:01:08,01 --> 00:01:13,07
and potential for design flaws and coding errors.

24
00:01:13,07 --> 00:01:16,05
When it comes to disadvantages,

25
00:01:16,05 --> 00:01:19,04
one of the biggest is support.

26
00:01:19,04 --> 00:01:23,06
Yes, the driving open source community often exist

27
00:01:23,06 --> 00:01:26,05
which is willing to support your product

28
00:01:26,05 --> 00:01:28,07
but there is no guarantee.

29
00:01:28,07 --> 00:01:33,04
Sometimes an open source project just disappears

30
00:01:33,04 --> 00:01:35,00
due to various reasons

31
00:01:35,00 --> 00:01:39,05
one of which could be the lack of funding or interest.

32
00:01:39,05 --> 00:01:45,05
Therefore, sustainability is another enormous challenge.

33
00:01:45,05 --> 00:01:49,02
If you need professional support for the solution

34
00:01:49,02 --> 00:01:54,02
you're adopting, a better route could well be commercial.

35
00:01:54,02 --> 00:01:59,03
Because of these pros and cons hybrid options are emerging.

36
00:01:59,03 --> 00:02:02,06
Companies make their product open source,

37
00:02:02,06 --> 00:02:05,05
but charge fees for customer support,

38
00:02:05,05 --> 00:02:10,06
extra features and feature upgrades.

39
00:02:10,06 --> 00:02:15,04
A good example is Snort that monetizes

40
00:02:15,04 --> 00:02:17,05
intrusion detection rules.

41
00:02:17,05 --> 00:02:21,06
Here, you can see the various subscription options

42
00:02:21,06 --> 00:02:23,06
the company is providing.

43
00:02:23,06 --> 00:02:26,05
You can even go for no support option

44
00:02:26,05 --> 00:02:30,08
if you have your own IT team with the right expertise.

45
00:02:30,08 --> 00:02:34,06
The nice thing about this trend is that the market

46
00:02:34,06 --> 00:02:39,09
is evolving to benefit the users and consumers.

47
00:02:39,09 --> 00:02:43,00
I have no problem with that.
