Here and welcome back into this, we will be discussing about the high availability aspect of Direct
Connect.
Now, one important part to remember is that if you have a single direct connect connection, it can
be subjected to the scenario of failure.
And this is something which you might face if you have a single direct connection.
Now, in the case of a direct connection, failure.
It can be a hardware failure.
It can be a network failure, etc. Your link will break completely.
So let's say that if one part of your application is need it, and second part is in your data center
and you have a direct connection between both of them.
And if data can take breaks, then your application will break.
So this is the reason why it is recommended to have a backup connection of VPN or the Internet.
And this is something which a lot of the organization, they do it.
So you're using you have on premise, you have Idalis.
And this is a single direct connect connection.
And if this breaks, essentially your link between your on premise and your database is broken.
So as a backup, you need to have something to which your compromised servers can connect to your alias.
So this is what we were referring to as this secondary backup connection of VPN.
So what happens here is that you have a single direct connect connection here and you have a backup
connection of VPN or the Internet.
So in this case, if this direct connect connection breaks, then the traffic can be routed over the
Internet to your eatables.
However, you will not have the same level of latency, the same level of speed or the VPN when it comes
to direct connect.
But you will definitely have your applications up and running.
So when it comes to the high availability of Direct Connect connection, there are two types of architectures
that you need to remember.
Now, we already discussed about the secondary backup connection or the Internet.
So this is something that you need to remember for the exams.
However, this type of secondary backup architected is not a direct connect architecture.
So that basically means that if you switch from data connectivity in the latencies the world, calls
that you might have and the speed the bandwidth will be reduced.
So you need to understand the architecture of high availability of direct connection itself without
VPN and with the VPN.
So that VPN is the architecture that we just discussed.
Let's discuss that without VPN architecture as well.
So in this type of architecture, so this is a dual connection, single location architecture.
So what happens here is that you have two routers on the side of the directory and you have two in your
customer site and both of them are connected.
So you have a single location.
So this entire location is in Mumbai region.
However, there are two connections which are available away.
So in case if one of the router fails to respond to certain reset, then you still have the second connection,
which is up and running through which you will be able to go, the traffic.
And this is important because this type of scenario is something that you might see within your organization
if you're using Direk.
So this is the reason why it is called dual connecting because there are dual connections for you,
but the location is a single location.
So although this is good, but this is not the best because everything is within this single location.
So the second type of architecture is dual connection and dual location.
So this is one of the best type of architecture that you can implement where you have two locations
for you.
So this is one location and this is the second location.
And in both of these location, you have the Direct Connect setup.
Now, same here.
You have two locations within your own premise which are connected, and both of them are connected
to the partner.
So this can be a customer or a partner and in turn, they are connected to the IWC.
Right.
So this is something that your organization can hope for if you have enough money and you really want
a good resiliency within your direct connect architecture.
So if you have something like this, then you do not really have to worry about a single direct connect
link going down and you have to switch to BP and you don't have to worry about that.
You can use this type of architecture.
And on top of this architecture, you can make use of VPN as the final option.
So you have a dual connection, dual location, plus the VPN as the last backup.
So this type of architecture is something which is preferred.
So this is about the high availability aspect of direc and I hope.
Studio has been informative for you, and I look forward to see you in the next video.
