Hi Shamil, If we create three NAT gateways in one AZ each, you will have to create separate route tables for that layer. You can’t have multiple NAT gateways in a single route table.

[@ajitinamdartech]

Hi Kathiravan, Can you please elaborate on this.

First of all, thank you so much for this excellent video. I wonder why do we need a jump server? just for our own access or what else? From what I understand, ALB is accessible from the internet and people access our server through ALB. However I couldn't understand why we created a jump server.

[@ajitinamdartech]

Hi, Jump server is required to access private resources like EC2 and RDS instances, ALB won't give you access to the servers.

When configuring ALB, initially Public Subnets is selected along with their respective AZs, but in the target groups App/Private Server is selected... So I am having a doubt that we need to route the traffic to the APP Servers of the Private Subnets then why Public Subents are selected initially??

Hi Jay, We need the ALB to be deployed across the public subnet as it needs to be accessible over the internet. However your app servers can be in a private subnet.
