AWS : EC2 Instance Public IP : Could not connect to Internet : Windows EC2 Instance
https://intellipaat.com/community/42232/aws-ec2-instances-are-not-getting-to-internet-access
For Internet Access -
A VM should be having Public IP address if its in Public Subnet and that Subnet should have Internet Gateway and Internet Gateway should have a route in Routetable
If a VM is in Private Subnet, It should have private IP and should have access to NAT Gateway in RouteTable of that Subnet
AWS : IGW vs NATGW
Internet Gateway (IGW) allows instances with public IPs to access the internet.
NAT Gateway (NGW) allows instances with no public IPs to access the internet.
IGW allows Outside traffic to go in
NAT-GW does not allow Outside traffic to come in, It only allows from inside to Outside
