1
00:00:02,200 --> 00:00:07,900
Now I talked a lot about replica sets, sharding and that we'll see something about that when we deploy

2
00:00:08,080 --> 00:00:09,520
our mongodb server,

3
00:00:09,520 --> 00:00:11,300
now it's finally time to do this.

4
00:00:11,380 --> 00:00:15,370
We want to get our localhost mongod instance into the web,

5
00:00:15,370 --> 00:00:22,060
so we want to get it on a server that we can reach from anywhere and not only from well our inside our

6
00:00:22,090 --> 00:00:28,530
computer. Now deploying a mongodb server is a complex task,

7
00:00:28,540 --> 00:00:34,420
it's definitely more complex than just deploying a website because you need to do a lot of things,

8
00:00:34,420 --> 00:00:39,550
a lot of configuration. You need to manage shards if you want to have sharding,

9
00:00:39,550 --> 00:00:46,390
you need to manage your replica sets, you have to set up user authentication and with that, I mean authentication

10
00:00:46,390 --> 00:00:48,250
to the database, not users

11
00:00:48,250 --> 00:00:53,860
your application, your website might be using. You need to protect the web server and the network which

12
00:00:53,860 --> 00:01:00,910
is now totally unrelated to mongodb but a general web hosting task. You need to ensure that software

13
00:01:00,910 --> 00:01:01,840
stays up to date,

14
00:01:01,900 --> 00:01:06,760
general server software but also of course mongodb related software, that security

15
00:01:06,760 --> 00:01:12,220
patches are applied. You want to set up regular backups for your data,

16
00:01:12,220 --> 00:01:18,130
you might have replica sets and still backing up data to a disk might be an additional good idea in

17
00:01:18,130 --> 00:01:24,340
case that everything goes down. And you also want to worry about encryption, both during transportation

18
00:01:24,430 --> 00:01:25,930
and at rest.

19
00:01:25,960 --> 00:01:31,540
So there are a lot of complex tasks that you have to manage when deploying this and I'll be very honest

20
00:01:31,540 --> 00:01:38,250
with you, this is beyond the scope of most developers and beyond my scope too, I'm not a system administrator.

21
00:01:38,370 --> 00:01:45,580
Therefore in this module, I'll show you a managed solution, mongodb atlas is a service provided by mongodb,

22
00:01:45,580 --> 00:01:48,090
by the company behind mongodb

23
00:01:48,310 --> 00:01:55,900
that gives you a scalable and best practice mongodb server running in the cloud which you can

24
00:01:55,900 --> 00:02:01,760
configure through a convenient interface and which you can scale up, scale down.

25
00:02:01,780 --> 00:02:08,560
There is a free tier available, so you can start for free even and it gives you all these things I mentioned

26
00:02:08,560 --> 00:02:10,770
on the last slide automatically,

27
00:02:10,780 --> 00:02:14,770
so it does all of that for you so that you don't have to worry about that.

28
00:02:15,010 --> 00:02:20,090
So let's now take a look at mongodb atlas and let's see how we can deploy a

29
00:02:20,090 --> 00:02:22,960
mongodb server there and how we then can connect to it.
