Video Transcription

00:00
hello and welcome back to the course.
00:03
In our last video, we successfully logged into our private server from our public server
00:09
using SS H agent forwarding.
00:13
We quickly discovered, however,
00:15
that we were unable to perform a U. M update on the server
00:18
because it has no gateway to the Internet.
00:21
In this video,
00:23
we will add in that gateway and then attempt to update our private server again.
00:29
So, just as a quick review, what is it that giggling
00:34
the network address? Translation. Gateway is a highly available AWS managed service
00:41
that makes it easy for us to connect to the Internet. For Marty, see two instances
00:46
that are located within our private sub net.
00:49
Prior to the introduction of the Net Gateway in 2015
00:53
we would have to configure a monitor at least two E. C. Two instances in the cluster for high availability toe actors are in that gateway.
01:03
It just added additional complexity and monitoring to R V P. C.
01:07
With the Nat Gateway,
01:10
it WS handles all of the netting for us.
01:12
The gateway has built in redundancy for high availability.
01:17
Each gateway that we create can handle up to 10 gigabytes per second of bursting
01:23
T C P u T P
01:25
and I see MP traffic.
01:26
All that we need to do
01:29
is a sign an elastic I p address when we create our gateway
01:33
which I will show you how to do shortly.
01:37
So
01:38
let's connect today W s consul
01:42
then pullup are easy to dashboard.
01:51
We should have two running instances
01:57
our public and private servers.
02:01
So now let's go back to the console
02:05
and pull a power. Vpc dashboard
02:21
didn't select Nat Gateways from the menu on the left
02:27
Quick create Nat Gateway
02:36
Let's assign it to our public sub net.
02:44
We've never created an elastic I p to this point. So select create new E i p
02:52
and then click created that gateway
03:02
while are not ***, was spinning up.
03:05
Let's quick close
03:07
the net Gatewaycan take a few minutes toe become available so I will speed up the video a little
03:21
So now it's available in AWS has assigned us in the last guy p
03:27
One thing that I will mention is that the I p addresses and that gateways do encourage charges.
03:32
So make sure that you delete the gateway when you complete this lap
03:39
next we will need to edit our route table in our private sudden it
03:51
so select the private, sudden it
04:01
and then click edit routes.
04:03
We were at a default route that will send all traffic to the Net Gateway
04:16
and then save the route
04:19
So we're now ready to test.
04:24
Let's go back to the AWS Council and pull up the EEC to dashboard
04:36
and get the address of our public. Easy to instance.
04:42
Then let's go back to my limits. Instance.
04:46
Let's add the private key again to memory,
04:59
then verified that it's there.
05:05
Cool. It's a memory.
05:08
I'll clear my screen
05:10
and let's log into our public instance using sssh!
05:14
Agent forwarding.
05:30
Awesome! So we have successfully logged into our public instance.
05:34
Now
05:36
let's log into our private instance.
05:40
Let's go back to the easy to dashboard to get the private I P address,
05:50
copy it to the clipboard
05:58
and try to log in.
06:09
Great. So we have authenticated successfully.
06:13
Now let's make ourselves route
06:18
and attempt the Yum update again
06:30
and awesome are not. Gateway is working like a charm.
06:35
Our private instance can reach out to the Internet for its updates.
06:40
Great job. Everyone
06:44
in our final video. In this section,
06:46
we will create an A C L for a private summit
06:49
and then launch our first D B server.
06:53
So see you in the next video.
