Here are some of the things that ChatGPT has taught me.

Use a Lambda to check network connectivity

I asked ChatGPT (GPT-4) for a simple way to test VPC network connectivity without creating an EC2 instance in AWS.
It proposed creating the following lambda function that I could then configure in any of my VPCs and subnets. It works great!

import socket
import json
