>> Hello everybody and welcome back.
00:00
In this lecture we're going to talk about
00:00
Site-to-Site VPNs and Gateways.
00:00
Learning objectives, there's just go
00:00
over the two different services, AWS Site-to-Site VPN.
00:00
We want to make sure that you understand
00:00
what is going on here,
00:00
because you may see a question
00:00
or two on this in your exam.
00:00
What is AWS Site-to-Site VPN?
00:00
Well, AWS Site-to-Site VPN
00:00
is exactly what it sounds like.
00:00
It's a VPN service,
00:00
VPN concentrator on the AWS side
00:00
that you can automatically attach
00:00
to your VPC to allow for
00:00
direct communication to your network.
00:00
Whatever it is the network
00:00
is that you're trying to communicate to.
00:00
A good example of this is,
00:00
let's say you're trying to get your VPC to
00:00
directly connect to the network
00:00
that you have in your office environment.
00:00
You can use Site-to-Site VPNs in order to do that,
00:00
to perform that very thing,
00:00
and it sets up
00:00
a direct IPsec VPN connection
00:00
between your VPC and your on-premise network.
00:00
Typically, this needs to be done
00:00
because you cannot communicate
00:00
with an EC2 instance from
00:00
your AWS environment to your private network,
00:00
your remote network, without doing some type
00:00
of communication process like Site-to-Site VPN,
00:00
you're going to need that in order to do that.
00:00
Or you can go over the public Internet,
00:00
of course, and you can SSH that way.
00:00
Listen, let's not just talk about EC2,
00:00
let's just talk about VPC,
00:00
the entire thing subnet.
00:00
If you're trying to get the entire subnet to
00:00
communicate with your on-premise network,
00:00
this is the best way to do that efficiently.
00:00
All the resources in your private network
00:00
can be seen by your VPC and vice versa.
00:00
You'll be able to set up all of that and it'll seem
00:00
a holistic and secure network connection.
00:00
That about wraps up this lecture.
00:00
In this lecture we talked about Site-to-Site VPN.
00:00
Really this is just to help you understand what this is.
00:00
You're going to want to know this
00:00
for your exam because you may see
00:00
a question on Site-to-Site VPNs going in.
00:00
If you see an architectural question that's like,
00:00
how do you get your VPC to
00:00
connect to your on-premise network?
00:00
Chances are Site-to-Site VPN may be a viable solution.
00:00
Be on the lookout for that answer there.
00:00
That about wraps up this lecture.
00:00
I'll see you guys on the next one.
