1
00:00.000 --> 00:05.000
So now that we have an idea what a cloud exchange is,

2
00:05.000 --> 00:10.000
let's move on and talk about software defined cloud interconnect

3
00:10.000 --> 00:13.000
or SDCI.

4
00:13.000 --> 00:17.000
Now this is very similar in function to a cloud exchange

5
00:17.000 --> 00:20.000
in that it's a method to connect an enterprise

6
00:20.000 --> 00:23.000
to again multiple cloud providers.

7
00:23.000 --> 00:28.000
The difference is this is generally a more sophisticated approach

8
00:28.000 --> 00:32.000
where it's using SDN or software defined networking
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

8
00:28.000 --> 00:32.000
where it's using SDN or software defined networking

9
00:32.000 --> 00:35.000
and we generally have a lot more features

10
00:35.000 --> 00:39.000
and things that we can do through this networking approach.

11
00:39.000 --> 00:41.000
So let's go ahead and jump in.

12
00:41.000 --> 00:47.000
We'll take a look at some of the advantages of SDCI.

13
00:47.000 --> 00:53.000
So SDCI and cloud exchanges are actually very similar

14
00:53.000 --> 00:57.000
in the fact that both of these facilitate connecting

15
00:57.000 --> 01:00.000
the enterprise to multiple cloud providers.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

16
01:00.000 --> 01:05.000
It's just the method that's used for each one is slightly different.

17
01:05.000 --> 01:11.000
SDCI generally offers a much more comprehensive

18
01:11.000 --> 01:15.000
and flexible approach to connecting those enterprises

19
01:15.000 --> 01:19.000
to the cloud services because they use SDN

20
01:19.000 --> 01:22.000
or software defined networking.

21
01:22.000 --> 01:26.000
Where things like cloud exchanges are often offered

22
01:26.000 --> 01:30.000
at things like co-location providers.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

23
01:30.000 --> 01:36.000
SDCI services are often part of a broader offering

24
01:36.000 --> 01:41.000
from cloud service providers or alternately specialized

25
01:41.000 --> 01:45.000
networking companies that target enterprises implementing

26
01:45.000 --> 01:47.000
multi-cloud strategies.

27
01:47.000 --> 01:50.000
So generally your larger enterprises.

28
01:50.000 --> 01:53.000
So that of course begs the question,

29
01:53.000 --> 01:59.000
in what scenarios does SDCI really benefit a company?

30
01:59.000 --> 02:01.000
So let's start with the two biggest.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

30
01:59.000 --> 02:01.000
So let's start with the two biggest.

31
02:01.000 --> 02:06.000
The first one would be a company that is first moving to the cloud.

32
02:06.000 --> 02:09.000
This gives companies a really easy way to do it

33
02:09.000 --> 02:12.000
just by signing up with an SDCI provider

34
02:12.000 --> 02:18.000
and it's going to help if they want to connect to multiple clouds.

35
02:18.000 --> 02:22.000
So this is also very strong in multi-cloud connections.

36
02:22.000 --> 02:26.000
Again, much like a cloud exchange.

37
02:26.000 --> 02:29.000
Also since these are available all around the world,

38
02:29.000 --> 02:33.000
this is going to help tremendously with geographically
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

38
02:29.000 --> 02:33.000
this is going to help tremendously with geographically

39
02:33.000 --> 02:38.000
diverse customers who have locations all around the world.

40
02:38.000 --> 02:43.000
And the interesting thing about that is not only can this then help

41
02:43.000 --> 02:45.000
with those site to cloud connections,

42
02:45.000 --> 02:48.000
which is sort of what we're focusing on here,

43
02:48.000 --> 02:54.000
but SDCI can actually be used for sites to site connections as well,

44
02:54.000 --> 02:58.000
basically acting as your WAN connections.

45
02:58.000 --> 03:03.000
And in most scenarios, SDCI is going to be using better circuits,
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

45
02:58.000 --> 03:03.000
And in most scenarios, SDCI is going to be using better circuits,

46
03:03.000 --> 03:07.000
better throughput than what's available to an average customer.

47
03:07.000 --> 03:13.000
So oftentimes this is going to be very beneficial for low latency applications.

48
03:13.000 --> 03:17.000
So these are some different scenarios where a company might benefit

49
03:17.000 --> 03:19.000
from using SDCI.

50
03:19.000 --> 03:25.000
Let's talk about some of the benefits of the SDCI solution itself.

51
03:25.000 --> 03:29.000
First, we have enhanced connectivity.

52
03:29.000 --> 03:34.000
Like I said, these are generally going to be direct and private connections.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

52
03:29.000 --> 03:34.000
Like I said, these are generally going to be direct and private connections.

53
03:34.000 --> 03:38.000
They're going to have connections to various cloud providers,

54
03:38.000 --> 03:41.000
just like cloud exchanges do.

55
03:41.000 --> 03:45.000
And again, because of the nature of these being private connections,

56
03:45.000 --> 03:50.000
these are going to be definitely faster and lower latency compared to something

57
03:50.000 --> 03:53.000
like the traditional internet.

58
03:53.000 --> 03:59.000
SDCI also offers increased flexibility and scalability.

59
03:59.000 --> 04:03.000
This is generally going to be some form of on-demand connectivity.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

59
03:59.000 --> 04:03.000
This is generally going to be some form of on-demand connectivity.

60
04:03.000 --> 04:08.000
We can scale up and scale down the bandwidth as needed.

61
04:08.000 --> 04:13.000
The connections can be again managed across multiple cloud providers.

62
04:13.000 --> 04:16.000
We can add and remove those providers as needed.

63
04:16.000 --> 04:22.060
And all of that management is handled through a centralized software control

64
04:22.060 --> 04:23.000
plane.

65
04:23.000 --> 04:26.000
Just like we discussed with cloud exchanges,

66
04:26.000 --> 04:32.000
this is also going to be improved security simply because we are in fact using
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

66
04:26.000 --> 04:32.000
this is also going to be improved security simply because we are in fact using

67
04:32.000 --> 04:34.000
private connections.

68
04:34.000 --> 04:39.000
So that just by its nature is going to be more secure compared to again,

69
04:39.000 --> 04:41.000
using something like the internet.

70
04:41.000 --> 04:46.000
In a lot of situations, this is also going to provide cost efficiency.

71
04:46.000 --> 04:49.000
This is generally a pay as you go system.

72
04:49.000 --> 04:53.000
So you're only going to be paying for what you use.

73
04:53.000 --> 04:59.000
And we can optimize our network based on our usage and costs.

74
04:59.000 --> 05:02.000
And they usually have very good tracking systems.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

74
04:59.000 --> 05:02.000
And they usually have very good tracking systems.

75
05:02.000 --> 05:05.000
So we know what our usage and costs are going to be.

76
05:05.000 --> 05:11.000
Once we know that, we can take advantage of the more precise control over these

77
05:11.000 --> 05:19.000
network resources to again help control our costs in this pay as you go system.

78
05:19.000 --> 05:25.000
And finally, we have a big advantage with our simplified management.

79
05:25.000 --> 05:32.000
We can combine SDCI with SD WAN and really simplify our management.
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

79
05:25.000 --> 05:32.000
We can combine SDCI with SD WAN and really simplify our management.

80
05:32.000 --> 05:37.000
It's going to support automated circuit setup, circuit segmentation.

81
05:37.000 --> 05:41.000
We can use it to deploy our policies and so on.

82
05:41.000 --> 05:47.000
So very, very simplified management by combining this with our SD WAN

83
05:47.000 --> 05:48.000
environment.

84
05:48.000 --> 05:54.000
So in this video, we got a good introduction to software defined cloud

85
05:54.000 --> 05:57.000
interconnect or SDCI.

86
05:57.000 --> 06:03.000
Again, this is another method to connect our enterprise out to multiple cloud
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

86
05:57.000 --> 06:03.000
Again, this is another method to connect our enterprise out to multiple cloud

87
06:03.000 --> 06:09.000
providers through a single connection, but in a much more sophisticated and

88
06:09.000 --> 06:14.000
manageable system than we have with most cloud exchanges.

89
06:14.000 --> 06:19.000
So that concludes everything that we need to discuss in this skill.

90
06:19.000 --> 06:22.000
That leaves us with just our challenge.

91
06:22.000 --> 06:28.360
So go ahead and attack that challenge and I'll see you in the solution video on

92
06:28.360 --> 06:30.000
the other side.
