You know the feeling when you get a new idea and would like to start building right away, and then run into road block of getting IP addresses allocated for a new VPC. But unless you get CIDR from the network team, it is likely you have to tear down everything and start from scratch later when you want to connect with other services or internal networks. Or simply answering the question “how many IPs do you need?” isn’t possible because you are still evaluating different architecture options. Would it be possible to get best of the both worlds? Start independently, without risking future connectivity.

In Where is my bastion host? and EC2 Instance Connect vs. SSM Session Manager I wrote about how to connect to EC2 instances inside a VPC without having to run a bastion host exposed to Internet but using the AWS API as the contact point. While this arrangement has many advantages over running your own server/service there is still one important use-case it can not do.
