At the moment, AWS ALBs can't be associated with elastic IPs. This module provides a way to resolve this problem by implementing the solution based on the following article: https://aws.amazon.com/blogs/networking-and-content-delivery/using-static-ip-addresses-for-application-load-balancers/
- Public facing NLB with a set of elastic IPs, one for each public subnet
- Internal ALB
- S3 access log bucket for both LBs
- Lambda function that is responsible for the attachment of ALB IPs to the NLB target group
- S3 bucket and cloudwatch resources that accompany the lambda function above
