Hi, everyone, and welcome back.
Now into this video at a high level overview, we are going to discuss about the IP attachments to Nhlbi.
Now, there are certain important pointers that you need to keep a note of.
First one is that the network load balancer automatically provides a static IP per availability zone
that can be used by the application as a front end IP for your load balancer.
Along with that, in case if you require network load balancer also gives you the option to assign an
elastic IP per availability zone if required.
And yet also one point to note is that after a network load balancer is created, you can no longer
modify its existing subnet or NLB node's elastic IP addresses.
So let's do one thing.
Let's go ahead and quickly explore this from demo perspective.
So currently from the load balancer console, whenever you go ahead and you create a load balancer,
let's go a bit down.
Let's assume that we select a specific subnet.
So in the IPV four address, you can use the assigned by A or you can also use a elastic address.
For example, let's do one thing.
Let's quickly create an elastic address.
So this is one elastic IP.
Let's go back to the load balances.
When we create a load balancer.
This time you can use the elastic address.
This is the elastic IP that is available.
Now, one more important architecture pattern that you have to understand is associated with the network
load balancer and the application load balancer.
So at the overview, you have to note that you cannot assign a static IP address to the application
load balancer.
So in case if there is a requirement in your organization where static IP address is a must, then what
you can do, you can register the application load balancer behind the network load balancer.
This is also something that is possible.
For example, if you look into this specific architecture, you have a network load balancer.
Behind it is the application load balancer and behind it is the appropriate target group.
So sometimes in exams, if you see a scenario where a static IP address is required for application
load balancer, you can make use of the NLB grid.
So that's the high level overview.
And with this will conclude today's video.
