Create a Private Microservice Using an Application Load Balancer

Image
Previously if you wanted to create an REST API powered by a lambda you only had one choice: API Gateway. This has a few limitations notably they’re always public so you need to use IAM or similar to lock it down and you can only use a custom domain name once globally, meaning no duplicating the implementations across multiple accounts with the same host endpoint. AWS recently announced another way to create a RESTful endpoint for Lambda’s: Application Load Balancers.
