How to create an HTTPS certificate for localhost domains

If these helped you, I'd love to hear about it!! I'm on twitter @vcarl_ or send me an email

  2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
  3. VPC with NAT, The best of both worlds, AWS services and web.
