Section note: This section introduce the notion of private subnet and NAT

Create a new subnet
Explain the routing only internal to the subnet itself
Spin up a new machine EC2
Explain Bastion and/or SSM to SSH into the instance
Present the upgrade problem (my machine needs to be able to download updates) (probably touch upon SG but can explain on the next part)
Introduce NAT and advanced routing

CIDR in depth

Subnet is a slice dedicated to AZ of your VPC
Each subnet has a type that defines the behavior of network for machine within the subnet
there is 5 types, we will focus on 2 (public/private)
Public subnet allows individual resources within it to access the internet and be accessed from the outside thanks to IG
- Real scenario example with technicalities here
Private subnet does not allow individual resources to be accessed from the outside and resources needs to pass through a component to access the internet (NAT)
- Example of an ubuntu machine that can not be reached outside the subnet but requires update of packages
