Convert AWS IAM credentials to AWS SMTP credentials

If you do, or want to, use AWS to deploy your apps, you will end up using AWS SES via SMTP when you're launching an app that sends out emails of any kind (user registrations, email notifications, etc). For example, I have used this configuration on various Ruby on Rails apps, however, it is just basic SMTP configurations and crosses over to any framework that supports SMTP sendmail.

There are two ways to go about this:

EASY WAY: Create an SMTP user via AWS SES [http://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.html#smtp-credentials-console]
NOT SO EASY WAY: Create an SMTP password for an existing IAM user [^^ Same link scroll down]

Luckily, you found this MD file and the NOT SO EASY WAY is suddenly copy-pasta... sudo yum....

Envoy TCP Proxy

This is an example of Envoy TCP Proxy from localhost:10000 to www.google.com:80. See also https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/listeners/tcp_proxy.

To run a proxy:

% docker run --rm getenvoy/envoy:stable --version

	using System.Threading.RateLimiting;

	var builder = WebApplication.CreateBuilder(args);

	builder.Services.AddRateLimiter(options =>
	{
