Thanks for the kind words!

To answer your questions:

1: Currently, you would indeed need to have one master in one region, but you could have RDS read replicas in other regions. With Amazon RDS, you can create a MySQL, PostgreSQL, or MariaDB Read Replica in a different AWS Region than the source DB instance.

You can also do multi-master with Aurora (in preview only) within one region and we have announced multi-master multi-region for Aurora for 2018 — which should solve the last piece of the puzzle.

You can read more about that in my previous blog post in this series:

2: Deploying a lot of services is always the one thing that is tricky… but I personally like splitting things into micro-services — and if I would add 30 lambdas to handle my 30 APIs — my template would just be longer :) I would also use AWS X-ray to help me debug. As for Express, check out this project: this might help you get started.

Hope it help — let me know if you have more questions.
