Hello Everyone

Welcome to CloudAffaire and this is Debjeet

In the last blog post, we have created a private subnet inside our VPC and hosted one EC2 instance in it.

In this blog post, we are going to create a new private subnet and a custom route table. We will also explicitly associate this new subnet with our custom route table. Below is the configuration diagram for this demo.

We are going to create our new private subnet using 10.0.2.0/24 IPv4 CIDR.

Note: We will use this same VPC and existing configuration in upcoming blogs, hence if you wish to continue then don’t delete your VPC.

In the next blog post, we are going to prepare our VPC for internet connection.
