如何获取网络访问AWS VPC？

Question

I have a non-private AWS VPC built on a Centos 7 image, however I am unable to to a yum update. Can you help me troubleshoot how I can get connection to the outside.network to do updates and downloads?

here what I have to see so far:

command:  echo $https_proxy

command: $ sudo yum -y update

Private VPC does not have inte.net access.

To enable inte.net access need to setup inte.net gateway and make one of your su.nets public. Instances in that su.net will be able to access inte.net and be accessible from the inte.net.

If your instances are in a private su.net, and you want your instances to have inte.net access, but not be accessible form inte.net, then have to setup NAT gateway or NAT instance .
